Increasing Demand for Reusing Waste Plastics in Consumer Electronics

The demand for reusing waste plastics in consumer electronics and other products is increasing. Traditionally, the general recycling process involved manually dismantling plastics of single materials. However, as the movement to conserve the global environment and effectively utilize limited resources gains momentum, the reuse of crushed scraps containing multiple types of plastics has begun.

To meet the rising demand for recycling, the method of sorting crushed scrap materials has become a crucial point. Ishikawa Wire Mesh offers a new electrostatic separation system.

This system addresses the challenge of electrode collision leading to mixing, which is a drawback of the electrostatic separation method, by adopting circular electrodes. As a result, it enables the high-purity separation of plastics with similar physical properties, such as polypropylene and polyethylene, which are commonly collected through eco-cap movements with PET bottles.

Compared to infrared separation systems, this system can be introduced at about half the cost. The product uses a system invented by Professor Nobuhito Saeki of the Department of Mechanical Engineering, College of Engineering, Shibaura Institute of Technology (joint patent application pending).

Sintered Metal Mesh

Reliable filter material and filter media using sintered metal mesh. Various combinations are possible depending on your application When :

• Uniform filtration accuracy is required
• Strong pressure resistance is needed
• Repeated regeneration is necessary
• Pressure loss needs to be reduced
• Removing or granulating gels in polymers

We will conduct differential pressure (pressure loss) tests using an extruder upon request. We will consider the optimal combination by examining conditions such as the input method, kneading method, and additives. You can select from the filter media specification table.

Four types of sintered metal mesh

Ishikawa Wire Mesh offers four types of sintered metal mesh and screens.

Type A: Sinter Metal Wire Cloth (SMWC)

Sintered woven wire mesh. By maintaining the woven wire mesh at temperatures around the metal’s melting point for a certain period, crystals form across the contact points within the metal structure, resulting in complete integration. This process maintains high strength without opening the mesh and prevents expansion due to pressure, while also preventing wire unraveling. Uniform accuracy is maintained until the wire breaks under pressure. However, due to heat treatment, it becomes more flexible compared to before heat treatment. It is similar to a welded state, so it has less flexibility in mesh size and is prone to tearing or breaking under high pressure when used alone.

Type B: Sinter Metal Fiber Cloth (SMFC)

Sintered metal fiber. Metal fibers are opened into a web and sintered under controlled high-temperature conditions. This ensures that contact points between fibers are integrally bonded. This maintains high strength without opening the mesh and prevents expansion due to pressure. However, as it is a very thin material like paper, it is flexible and prone to folding, tearing, or breaking under high pressure when used alone.

Type C: Laminated Sinter Mesh (LSM)

Sintered woven wire mesh of Type A. When used alone, it is prone to folding, tearing, or breaking under high pressure. However, by using a thicker, stronger woven wire mesh as a reinforcement mesh and incorporating a guarantee mesh in a multi-layer structure, high pressure resistance and durability are ensured, making it resistant to backwashing and allowing for repeated cleaning.

Type D: Laminated Sinter Mesh & Fiber Cloth (LSM&F)

Sintered laminated woven wire mesh and nonwoven fabric of Type A and Type B. When used alone, Type A and Type B are prone to folding, tearing, or breaking under high pressure. However, by using a thicker, stronger woven wire mesh as a reinforcement mesh and incorporating a guarantee mesh and metal nonwoven fabric in a multi-layer structure, high pressure resistance and durability are ensured, making it resistant to backwashing and allowing for repeated cleaning.

Reliable Filtration Media and Filter Media Using Rolled Wire Mesh. Various combinations are possible according to your usage.

• Uniform filtration accuracy is required
• Strong pressure resistance is needed
• Repeated regeneration is necessary
• When wanting to reduce pressure loss
• When removing gel from polymers or refining the gel into fine particles

We conduct differential pressure (pressure loss) tests using extruders according to your requirements. We carefully examine conditions such as injection methods, kneading methods, and additives to consider the optimal combination. You can select from the filter media specifications table.

Three Types of Rolled Wire Mesh

Ishikawa Wire Mesh offers three types of rolled wire mesh and provides screens.

Type A: Rolled Wire Mesh (Calendar Screen / CS)

This woven wire mesh has undergone rolling processing. By applying rolling processing, we firmly combine the intersections of the wires, maintaining high strength with no open gaps. Additionally, you can control the thickness according to the rolling conditions. Furthermore, as the surface becomes flatter, the open gap size decreases even with the same mesh. When used as filter media, the open gap size is verified through bubble point tests. The term “calendar” in calendar screens originally means a polishing process. The rolling conditions give the wire mesh a sheen, making it usable for decorative purposes as well.

Type B: Laminated Rolled Wire Mesh (Laminated Calendar Mesh / LCM)

We use strong woven wire mesh with a thick wire diameter that has undergone rolling processing as a reinforcing mesh. To ensure high pressure resistance and durability, we employ a multi-layer structure with a guarantee mesh in between. It withstands backwashing and can be repeatedly cleaned. The difference from sintering processing is that we laminate the woven wire mesh through resistance welding (spot welding).

• Type B-1
  • Pressing and crushing the outer edge of Type B improves seam performance, preventing leakage from the outer edge.
• Type B-2
  • Attaching a frame to the outer edge of Type B improves seam performance, preventing leakage from the outer edge.

Type C: Laminated Rolled Wire Mesh & Fiber Cloth (LCM&F) Using strong woven wire mesh with thick wire diameter that has undergone rolling processing as a reinforcing mesh, a multi-layer structure with a guarantee mesh and metal non-woven fabric in between ensures high pressure resistance and durability. It withstands backwashing and can be repeatedly cleaned. The difference from sintering processing is that the woven wire mesh is laminated through resistance welding (spot welding).

• Type C-1
  • Pressing and crushing the outer edge of Type C improves seam performance, preventing leakage from the outer edge.
• Type C-2
  • Attaching a frame to the outer edge of Type C improves seam performance, preventing leakage from the outer edge.

Demisters made from layered knit mesh

Various shapes can be manufactured according to requirements.

Demisters made from knit mesh have an extremely high void ratio of 94% to 99%, allowing them to minimize the pressure loss of passing mist. Additionally, they can achieve a large surface area, making them lightweight and ensuring that most of the wire surface comes into contact with the gas.

When mist passes through the demister, the gas components in the mist pass through the gaps in the knit mesh. While the liquid components in the mist contact the surface of the knit mesh, coalesce (aggregate), and eventually drain as liquid.

You can use them in various separators to drain oil mist. Commercial air conditioners, smoke removal equipment, intake snappers, and other devices employ them.

We can freely consider and manufacture according to the usage conditions, environment, and installation location. Please also consult us about replacing knit mesh and other support.

Wedge Wire Screen Smooth, High Strength, High Precision Pursuing the Potential of Wedge Wire

At Ishikawa Wire Mesh, we manufacture and process products related to wedge wire, along with woven wire mesh. Wedge wire excels in surface smoothness, making it ideal for high-efficiency screening operations with granular materials. Recently, we have improved forming precision, and fine wedge wire with a slit width of less than 200 microns allows for finer operations. We flexibly respond to customer requests, from simple part processing contracts to detailed consideration of machine-specific details and proposing optimal wedge wire for target particles and usage environments. We are also actively developing new applications, such as applying wedge wire as an intermediate function between breaker plates and screens in resin extrusion molding machines.

High-function Screens with High Design Freedom

What is Wedge Wire? It mainly involves arranging wedge-shaped irregular wires at equal intervals to form fine slits (slots). Various open rates and strengths are achieved by combining the linear shapes and rods that form the screen. Regardless of industry or location, it can be used for filtration, solid-liquid separation, classification, dehydration, and concentration.

Features of Wedge Wire

• High Strength
  • Welding all intersection points ensures high mechanical strength. Depending on the usage environment and material, it may not need to be replaced semi-permanently, reducing running costs.
• High Precision
  • The high mechanical strength allows for precise control of passing particle size.
• Excellent Wear Resistance
  • Composed of thick wire materials, it excels in wear resistance.
• Fast Processing Speed
  • The smooth surface allows processed materials or catalysts to flow smoothly.
• Less Clogging
  • The “reverse triangular shape” means that solid materials have fewer contact points and the flared slit is less prone to clogging. Even if it does clog, the high backwash effect makes maintenance easy.
• High Dehydration
  • The small contact area when passing through the screen ensures excellent dehydration.
• Easy Maintenance
  • Due to its high rigidity and dehydration properties, it has excellent resilience and is easy to maintain.
• Wide Range of Design Flexibility
  • With rich processing variations, we can shape it into various forms such as flat, cylindrical, or conical.

Applications

• Dehydration machine elements
• Filters
• Centrifuge parts
• Vibrating sieve machines
• Solid-liquid separation devices
• Strainer elements
• River and seawater intake treatment equipment
• Catalyst and filter media holders such as activated carbon and ion exchange

High Design Freedom

• With rich processability, we can shape it into various forms such as flat, cylindrical (inner or outer wrapped), and conical.
• You can freely select and easily adjust slot sizes, allowing for flexible specification changes.
• In addition to stainless steel, we can also make it from special materials such as titanium, Hastelloy, and Monel.

We propose combinations of wire mesh and equipment tailored to your company’s situation

Ishikawa Wire Mesh provides advanced technology related to wire mesh, such as the “ultrasonic vibrating sieve.” From the perspective of a specialized wire mesh manufacturer, we propose the best matching of ultrasonic transducers and screens.

We adopt a sweep vibration method, which significantly reduces the setup effort that was difficult with the traditional single-wavelength resonance method of rings. This revolutionary product meets many on-site needs, such as reducing machine downtime and easy skill inheritance.

The composite frequency vibration uniformly amplifies the entire screen, improving sieving efficiency. By preventing stress concentration at specific parts of the wire mesh and using a system that does not require tapping balls, the screen’s lifespan can be extended, and productivity can be improved.

Effects

• Stable feed
  • Prevents powder bridging, reduces friction resistance on hopper sidewalls
• Increased sieving efficiency
  • Speeds up, increases processing capacity by 1.5 times with the vibrator attached
• Downsized sieving
  • Miniaturizes and lightens equipment, lowers screen costs used
• Upsized effect
  • Exhibits performance equivalent to large-area screens due to high processing capacity
• Extended wire mesh lifespan
  • Prevents screen damage, mesh opening, and mesh collapse due to long-term vibration
• Extended wire mesh lifespan
  • No mixing of different materials due to the absence of tapping balls

Target particle size and effects

• Effective for particles between 20 microns and 500 microns
• Significant increase in sieving efficiency for particles between 150 microns and 500 microns
• High effectiveness in preventing clogging for particles at 20 microns and 150 microns

Applications

• Fine powders: Titanium oxide, talc, calcium carbonate, abrasives, powder coatings, foundation, toner, ceramic powder, precious metal powders, lactose, powdered sugar, cornstarch, flour, food additives, pharmaceuticals, etc.

Since it can be installed later on existing machines, smooth introduction is possible. Detachment is very easy. We also have a handheld ultrasonic cleaning system for screen maintenance. If you have a test sample for sieving, please feel free to contact us.

Flexible metal mesh is ideal for resin manufacturing machine maintenance and is popular among machine users for cleaning extruder screws. Ishikawa Kanaami’s clean mesh is woven with flat wire, which has edges, so you can expect a high cleaning effect. Pure copper mesh is very soft, so unlike steel or stainless steel mesh, there is no risk of scratching the screw surface. Please wrap it around the extruder screw while the surface of the extruder is hot. It will scrape off any
resin remaining in the screw.

ISHIKAWA IK Screen Filter Exclusively For Resin Extruders Wire Mesh

Polyethylene and polystyrene, synthetic resins, have become as important as metals in modern industry. Their usage fields are also expanding. Accordingly, manufacturers worldwide are developing extruders suited to various synthetic resin processed products.

However, in order to produce high-precision, high-quality resin with any extruder, it is necessary to remove impurities such as foreign matter, carbonized matter, gel-like matter, unmelted resin, etc. from the molten resin that cause contamination. For this purpose, a screen pack supported by a breaker plate is indispensable.

Ishikawa Wire Mesh has been manufacturing and selling IK Screen®, a filter exclusively for resin extruders, since the 1960s, using the technology it has cultivated in wire mesh manufacturing. It can accommodate a variety of extruders and extruder melt screen changers. We have accumulated experience and technology in manufacturing screens for extruders since the 1960s, and have a system in place that allows us to flexibly respond to new types of screen packs.

At Ishikawa Wire Netting, we have achieved cost reductions while maintaining quality through streamlining our manufacturing processes, in-house mold maintenance, and global material procurement, and we are strengthening our prompt delivery system.

Ishikawa Wire Netting provides a recycling service to collect used IK Screens® and reuse them as new resources. This not only reduces the burden on the environment, but also helps reduce waste disposal.

Compatible with a variety of resin extruders

Resin extruders are becoming more popular along with processed resin products. Ishikawa Wire Netting has a track record of manufacturing screen packs using the following resin extruder models. We are also actively challenging ourselves to manufacture screen packs compatible with new types of resin extruders, such as single-layer mesh (mono type), multi-layer mesh type (spot type), and frame reinforcement type (frame type). Please feel free to contact us.

Main specifications of IK Screen® (filter for resin extruders)

The opening size of the wire mesh used for IK Screen® can be made to order, from 0.04mm to 16mm. Please refer to the woven wire mesh product list for the mesh types. The product list explains the features of the representative products.

Types of woven wire mesh

Plain weave:
A weaving method in which the vertical and horizontal lines intersect one another at regular intervals. This is commonly used as a standard wire mesh.

■ Twill weave:
This weaving method has vertical and horizontal lines spaced at regular intervals and crossing over each other two by two. Since two lines cross over each other, the angle of bending is large and it is possible to use relatively thick lines.

■ Herringbone twill:
We balance the twill weave by changing the weave at regular intervals to maintain the evenness of the folds.

■ Flat tatami:
Weave: A weaving method spaces the vertical lines apart while closely spacing the horizontal lines, resembling the surface of a tatami mat. Generally, we use thick vertical lines, resulting in high strength. (In the diagram on the left, the vertical and horizontal lines have the same diameter, so no gaps are visible in the horizontal lines, but in actual flat tatami weave there are gaps.)

■
Twill This is a twill weave of plain tatami weave. The horizontal wires are in close contact with both sides of the wire mesh, ensuring twice the strength of plain tatami weave. (In the left image, the vertical and horizontal wire diameters are the same, so no gaps are visible in the horizontal lines, but in actual twill tatami weave there are gaps.)

Product Form

IK Screen® shapes include round, square, donut, oval, etc., and can be manufactured in diameters from 10mm to 1000mm in 0.5mm increments. We

With Art Expanded Metal, you can create unique exterior designs at low cost.

Expanded metal has the highest productivity among all metal screens, so it can be produced at a relatively low cost. However, until now it has been produced as a crude industrial product, and has been used for gratings, steps, laths, etc., and has been difficult to use in front of design.

Ishikawa Wire Net’s Art Expanded Metal is a stylishly designed expanded metal imported directly from Mariani, Italy. It is worthy of the name “Art Expanded Metal” and is an easy-to-use building material that can be introduced at a lower cost than other design screens. We have a large inventory, so we can deliver quickly.

Art Expanded Metal domestic installation examples

Expanding a metal sheet and making staggered cuts with a blade creates expanded metal, a type of wire mesh.

Unlike wire mesh, which is made by weaving wire, expanded metal is made of diamond-shaped mesh fixed with a bond, which gives it strong tensile strength at each angle and unique shape and properties. You can use it for fences, passageways such as catwalks in factories, ventilation windows, cable racks, and construction and civil engineering materials .

Expanded metal is available in grating and standard types (iron and zinc-plated) based on JIS standards, as well as stainless steel and aluminum materials that meet JIS-compatible standards. In recent years, expanded metal has become widely used as an interior and exterior construction material. Ishikawa Wire Netting has a long delivery record and will make suggestions to suit your needs.

■Mesh The
diamond-shaped mesh that characterizes expanded metal is the mesh. The center-to-center distance in the short direction is SW, and the center-to-center distance in the long direction is LW.
■Strand
The lines that make up expanded metal are the strands. The cross section of the strands is rectangular, which helps prevent slipping when used in passageways. The strand thickness is T, and the strand width is W.
■Bond
The bond is the joint between the strands.
■Product dimensions
In the standard product dimensions of expanded metal, the dimension direction S = an integer multiple of the mesh dimension SW. Also, the dimension direction L = an integer multiple of the mesh dimension LW/2.

As shown in the diagram on the right, the mesh direction of expanded metal changes depending on the difference in the lengths of the dimensions L and S. We describe it as dimension L x dimension S, so when dimension S is shorter than dimension L it is an abacus pattern , and when dimension S is longer than dimension L it is a tatami pattern .

Expanded Metal Specification Table

We usually indicate the thickness of expanded metal as the strand thickness (T). However, during manufacturing, stretching the sheet while making cuts changes the overall thickness. We indicate the overall thickness as the total pressure. For more information, please see the Expanded List.

Perforated metal standard-length products are products with preset hole diameters, pitches, and dimensions. They are supplied as aluminum blanks, and the standards are unified, so we can respond to short delivery times. Please see the list of standard-length products.

For details on “Design Punching Panels,” which allow you to express designs using punched holes, please see Design Punching Panels Perforart®.

Second Processing

Ishikawa Wire Netting can perform secondary processing on custom-made punched metal products. Since secondary processing is carried out in our own factory, we can consistently manage quality and shorten delivery times for quick delivery.

Main processing examples

• Mounting hole processing (simple hole, loose hole, burring)
• Processing irregular cutouts, processing holes for doorknobs, etc.
• Diagonal panel processing for staircase slopes, and irregular panel processing for circles, etc.
• Bending
  Box bending, R bending, caulking support (hat bend), corner bending (outer corners, inner corners, etc.), crushing (hemming)
  Z-bending, L-bending, U-bending (U-shaped bending), and other compound bending processes welding
  • Joint welding, box processing welding, other welding
    Stud pin welding
    We will also consider processing if requested.

Surface Finish

• Raw materials (custom-made products, fixed-length materials)
  • The metal material is as is. Iron and aluminum are susceptible to corrosion and require some kind of surface finishing. If you would like to finish them yourself, we can provide them as raw materials.
    Please note that standard length materials are provided as raw aluminum materials.
• Paint finish (custom product)
  • The surface of the material is finished with paint. The advantages of a paint finish are:
    • You can color it as you like
    • Prevents corrosion
    • It is possible to achieve a finish that blends seamlessly with other materials such as plastic.

    There are various finishes available, such as acrylic paint, fluorine paint, urethane paint, photocatalyst paint, etc. We will consult with you about the finish according to your request.

• Anodized coating (anodized aluminum) (custom-made product)
  • This is a finish exclusively for aluminum. The surface is electrically oxidized to create an oxide film. The oxide film is hard and can give the material durability. Because it is an oxide film, the texture of the metal can be kept as it is. Silver and stainless colors (close to brown) are common, but recently various colored anodizing has also been used for automobile parts.
• Polished (stainless steel) (custom order product)
  • This is a finish exclusively for stainless steel, which is almost never corroded even when left as is. Finishes include 2D, 2B, and HL. We can provide a variety of finishes, from mirror finishes to hairline and almost no gloss finishes, making effective use of the metallic texture.

Please contact us to discuss the best finish for you. We will work with you to find the right one.

Materials

We process custom-made products using cold-rolled and hot-rolled steel sheets, galvanized steel sheets, surface-treated steel sheets, PVC steel sheets, high-tensile steel sheets, stainless steel sheets, aluminum, and colored aluminum.
If you have any other desired materials, please let us know. We will consider processing them.
The standard length material is aluminum A1050P-H24 plain.

Material shape

The maximum size of a sheet of material that can be processed into custom-made products is 1,585 mm wide and 4,000 mm long. For larger sizes, there are methods such as dividing the panel into multiple pieces, so please feel free to contact our experienced sales staff.

Design Punching Metal/PerfoArt for both Aesthetic and Functional Use in Architectural Interiors and Exteriors

PerfoArt is created using Ishikawa Metal Mesh’s developed software for punching metal design, “Punch Editor”. Design punching metal that combines aesthetic appeal and functionality, that’s Design Punching Metal/PerfoArt. Punching metal that doesn’t produce a whistling sound, that’s Design Punching Metal/PerfoArt.

High-definition designs are expressed through Punch Editor. Random designs and gradient designs have resolved the whistling phenomenon.

The standard material used is aluminum. Other materials can be produced based on hole diameter, so please contact us for more information.

We respond to requests for both mass production and small-lot, multi-variety orders.

Perforated Design Variations

1) Art Design
At Ishikawa Wire Mesh, we use our own techniques to create the perforated metal design you want, as long as you provide us with an original drawing, such as a rough sketch or photograph, whether in color or monochrome. Even if you do not have one, we can suggest a design that matches your image from our design collection.

2) Random design
: 8φ and 4.5φ holes are drilled randomly according to the opening ratio.
The opening ratio can be adjusted up to 40% according to customer’s request.
The holes are paired to reduce whistling noise.

3) Gradient Design The
gradient design is effective when you want to control the line of sight or the amount of light in a certain direction.
The opening rate is gradually changed from the edge of the panel to randomly perforated holes.
The opening rate can be set in the range of 0% to 40% according to the desired pattern.

4) Checkered design
Checkered design is a highly decorative design with continuous panels. Various patterns beautifully decorate the wall.
By combining 8φ and 4.5φ hole diameters, a lattice pattern is formed, and the variations are endless.

Perforated Fall Variations

In addition to the conventional A0C-Type, we can accommodate a variety of hole diameters and sizes.
We can also accommodate holes other than round holes.

1) A-Type 10φ＋4.5φ
2) B-Type 4.5φ　
3) C-Type 8φ＋4.5φ
4) Original pattern We will manufacture using a variety of multiple molds.

PITR-ART

Silicone rubber, new techniques using plastics, punching metal for interior and exterior use, Pitoart

Pito Art is an original technique developed by Ishikawa Wire Netting that combines punched metal with silicone rubber or plastic.
Pito Art embeds colored silicone rubber or plastic into punched metal, faithfully reproducing the colors of the original painting. You can experience the magnificent beauty of a mosaic mural. Furthermore, when installed near a window, it can create the glow of stained glass, and when backlit, it can create the effect of a neon sign. Pito Art is an evolution of punched metal.

Silicone rubber and plastic can be made in any color.
Silicone rubber and plastic can be processed into various shapes.
We can also provide silicone rubber and plastic only.
Currently, we only have 8mm diameter silicone rubber in stock.

Ishikawa Wire Netting began replacing screen doors (attaching wire mesh to screen doors) in the 1960s as a subcontract factory for Nippon Steel Corporation’s subsidiary, “Nippon Steel Curtain Wall.” It has been commissioned by sash manufacturers to replace screen doors and has been installing insect screens (wire mesh for screen doors) on a variety of sashes. We sell insect screens, rubber restrainers, and screen doors, and perform screen installation processing according to customer requests.
Insect screens (wire mesh for screen doors) come in a variety of types, from general resin (plastic) to durable wire mesh made of stainless steel.
Screen doors are made of a variety of materials, including aluminum, steel, and wood.
Screen installation processing (attaching wire mesh to screen doors) can be done for a variety of sizes, from small sashes to large sashes.

Insect screen (wire mesh for screen doors)

They are mainly used for screen doors and ventilation ducts, but there are various types of insect screens (wire screens) depending on the environment in which they are used, such as rural areas, mountainous areas, cities, cold regions, coastal areas, hot spring areas, etc.
Generally, they are made of plastic, but there are also metal ones such as stainless steel and aluminum.
We have a variety of insect screens available depending on the environment in which they are used.

Q. How effective is the insect repellent net?
Until now, the net was usually effective for three years, but with the development of new technology, the net is now effective for about six years.

Q.Is there a bug screen that blocks the view from outside?
There are black (inside) and silver (outside) bug screens that are difficult to see from outside but allow the view to be seen clearly from inside. They work
by using the diffuse reflection of sunlight to create a privacy effect. They are not effective at night or on windows that are not exposed to sunlight.

Q. Are there any screen doors that won’t tear even if pets (dogs and cats) scratch them with their claws?
There are pet defenses made
of polyester with a vinyl coating. Stainless steel wire mesh is even stronger.

Q. Can insects smaller than mosquitoes be prevented from entering?
The role of insect screens is to prevent insects from entering, but how many insects are prevented from entering depends on the environment in which they are used. The
size of the mesh of the insect screen also changes depending on the size of the insects.
Insect screens and screen doors sold in stores have 16 or 18 mesh. They
can accommodate insects the size of mosquitoes, but they cannot prevent smaller insects.
Also, in areas where dust is blown around, sand can get in through the mesh when the wind blows.
We have insect screens with finer mesh.

Q. My insect screen rusts quickly. Is there anything I can do about it?
In coastal areas, salty winds blow, so insect screens made of standard SUS304/stainless steel rust quickly.
We recommend SUS316/stainless steel wire mesh, which is relatively rust-resistant.
However, in areas where the screens are exposed directly to seawater, corrosion will progress quickly.
In that case, we recommend titanium, although it is more expensive.

Q. What are the standards for insect screens (wire mesh for screen doors)?
Insect screens are generally woven using a plain weave method. Vertical and horizontal lines are spaced apart and cross each other one by one.
The size of the mesh is measured in units of mesh. Mesh refers to the number of mesh holes per inch (25.4 mm). The
larger the mesh, the finer the mesh, preventing the intrusion of smaller insects.

Insect screens used in screen doors have a large void ratio so that the outside scenery can be seen easily.
The length between the lines is called the “opening”. It represents the size of the space in the mesh. The ratio of the space to the mesh is called the void ratio. It is expressed as void ratio (%) = 100 x (opening ÷ pitch)2. Even wire mesh with the same void ratio will have completely different openings, so when choosing wire mesh, you basically choose based on two values, mesh and wire diameter, rather than void ratio. A larger void ratio makes it easier to see the outside scenery, but to increase the void ratio, the wire diameter needs to be thinner for the same mesh. However, a thinner wire diameter reduces strength. The standards differ depending on whether you prioritize strength or transmittance.
Please refer to the standard table to select.

Specification

*This specification table lists general stainless steel insect screens (wire mesh). Please contact us for products not listed in this specification table.
*The standard length is 30m, but we can cut it to your desired length and width. An additional cutting fee will be charged.

Criteria for selecting stainless steel insect screen (wire mesh)

Type A is a standard product developed for residential screen doors.
Type B has a thicker wire diameter, making it stronger than the standard product. The
increased strength results in a lower void ratio, resulting in slightly lower breathability and permeability.
Type C is a standard for preventing the intrusion of smaller insects.
Type D is a standard set by fire prevention regulations for preventing ignition.
Ventilation ducts for hazardous material storage facilities. Used at the end of ventilation pipes in hazardous material facilities.
Type E is an insect-proof screen (wire mesh) used in metal fittings for ventilation openings.

Aluminum Insect Screen (Wire Mesh) Specifications Table

It is widely used for making screens for pet houses and for crafts.

Copper insect screen (wire mesh) specifications table

It is used for electromagnetic wave shielding.

Plastic Insect Screening Standards Table

1. PVC + fiberglass insect net: Rexnet (Nittobo)

RexNet is an insect-proof net made of a cloth woven from glass threads coated with polyvinyl chloride, which has been heat-set to prevent misalignment.
Wire mesh (stainless steel, aluminum, etc.) and synthetic fiber nets (polyvinyl chloride, polyethylene, etc.) are also used for screen doors, but RexNetR (glass fiber net) has the characteristics of glass fiber, such as high strength, dimensional stability, heat resistance, and non-flammability, and is coated with polyvinyl chloride, so it is corrosion-resistant and weather-resistant, and is very easy to set up as it does not sag, fray, or curl.
In addition, its calm coloring and beautiful appearance make it an attractive product, and it has established a unique position as a high-end synthetic fiber net and a substitute for wire mesh. It is particularly popular as the most common insect-proof net in foreign countries.

2. Polypropylene (PP) insect screen: Daionet (Daio Kasei)

3. Polyester (PET) insect screen: Silver Black Magic Net (Daio Kasei)

Silver Black Magic Net is a specially processed net that is black on the inside and silver on the outside. Its
unique feature is that it allows a clear view from inside the room, but makes it difficult to see inside from outside.

4. PVC + fiberglass insect screen: Daio Exceed (Daio Kasei)

DioExceed is a PVC-coated glass fiber net that is widely used overseas. It is
weather-resistant and durable, does not slip, is heat-resistant, and is less likely to get holes from cigarette fires.

5. Polyester/vinyl coated insect screen: Pet Defense (Daio Kasei)

“Pet Defense” is stronger than the “PP” netting that was previously used for screen doors, and is not easily torn by cats or dogs scratching.

6-1. Polypropylene (PP) + “Etofenprox” insect screen: Insect-repellent screen (Daio Kasei)

Insect-proof netting with chemicals for replacing screen doors. Insect-proof netting that keeps insects away. “Mushi-iya” effect that repels insects for about 3 years. Amid Mushi-iya high-quality domestic insect-proof netting.

Product Introduction of Insect-Replacement Net

An insect repellent net with completely new functions! It
has a double effect of both medicine and mesh.
When an insect touches the net, it takes effect and
the insect does not remain.
The medicine lasts for about 3 years, and
is stable and effective for a long time.
It does not evaporate or transpire, and has no odor.

Due to the effect of the chemicals, even if insects come, they cannot stay on the net and eventually fly away. The formula “keeps insects away without killing them”, so the amount of chemicals used is very small. Since it does not kill insects, the area around the windows will not get dirty.

*Effects vary depending on the target insect.

The insecticide seeps out little by little and remains stable for a long period of time, so trace amounts of drug are always present on the surface.

6-2. Polypropylene (PP) + “Vermethrin” insect-proof screen: Long-lasting insect repellent from screen doors (NBC Mesh Tech)

Insect-repellent netting with chemicals for replacing screen doors. Insect-repellent netting that keeps insects from staying on. Effectiveness has been extended. About 6 years!! The
double effect of the core-sheath structure and microcapsules allows the active ingredients that insects dislike to seep out from inside the thread to the surface of the thread.
The double structure ensures long-lasting effectiveness and safety!!

7. Polyester (PET) + Nafitec insect screen: Amidology (NBC Meshtec)
1) Amidology is super easy to clean

The super-hydrophilic finish makes it possible to remove dirt simply by pouring water on it, making the previously time-consuming task of washing screen doors simple and easy.
In addition, since detergents and other cleaning agents are no longer required, this is a very economical and environmentally friendly screen door net.

・”Photocatalytic” to break down dirt. ・”Super hydrophilic” to remove
dirt simply by pouring water.
・”Visibility” to suppress light scattering and provide excellent visibility.

2) Amidology Clean “Shining” Net

Nanoparticle fixation technology makes this screen net less susceptible to dust and dirt. This reduces the maintenance required for screen nets on skylights and windows with bars, which have been difficult to reach and clean up until now, and allows them to be kept clean and hygienic.

– Dustproof to prevent dirt and dust from sticking
– Ventilation to prevent clogging and allow for good ventilation
– Visibility to reduce light scattering for excellent visibility

3) Amidology – No insects allowed

Quality control is important in manufacturing sites. If even small insects get in, it can cause problems in terms of quality and management. “No Insects Allowed” has been developed by investigating flying insects and achieving a mesh size that insects cannot get in.
In addition, nanoparticle fixation technology makes it difficult for dust to accumulate and allows for sufficient ventilation.

– Insect-proof to prevent small flying insects from invading –
Dust-proof to prevent dirt and dust from sticking
– High opening rate for good ventilation
– High visibility by reducing light scattering

Criteria for selecting plastic insect screens

● Choose by mesh size
The mesh size is expressed as “mesh”, and the larger the number, the finer the mesh. Choose according to your preference for insect resistance and ventilation.

・18 mesh…1.15mm mesh. This is the net that is initially attached to the screen door.
・20 mesh…1.03mm mesh, the most economical replacement net. If ventilation is important to you, this is it.
・24 mesh…0.84mm mesh, the most popular with a good balance of ventilation and mesh.
・26 mesh…0.78mm mesh. A fine mesh net with enhanced insect repellency. Thin threads are used to ensure ventilation.
・30 mesh…0.67mm mesh. Even finer mesh. For those who are concerned about small insects.

●Choose by color
All relatively recent screen doors have black netting. This is because the black netting is less noticeable and allows you to see the outside scenery more clearly.
On the other hand, if you are concerned about people looking in from outside, choose “Silver Black Magic” or “Super Magic.”

・Gray: The former mainstream.
・White gray: A net that is quite close to white. It’s up to your preference.
・Black: The current mainstream. It gives you a clear view of the outside.
・Blue: While supplies last.
・Silver black: The outside is silver and the inside is black. It looks clear from inside, but blocks the view from outside.

●Choose by function
There are also nets with functions other than color and mesh.

・Silver Black Magic
For when you are worried about people looking at you from the outside.

・Net that insects hate
Double effect of mesh and chemicals. A new chemical-containing net that keeps insects away without killing them.

We want to explore the possibilities of metal screens – The excellent functionality of metal screens –

Installing a screen on the outside of a building to prevent heat from being absorbed by the exterior walls during the day and reduce air conditioning costs is expected to become more widespread in the future as CO2 reduction is required. We optimally procure materials that can be used for metal screens and provide products with an excellent balance of quality and cost for our customers.

Creative Metal Fabrication – Diverse Expressions

The expressive possibilities of wire art are limitless. Depending on the wire diameter and pitch, weaving method, material, etc., various expressions can be created according to the creator’s needs. We will contribute to the creation of one-of-a-kind architecture by producing innovative designs that have never been seen before.

Metal Fabric Durability High durability

The high durability of stainless steel wire is a great asset not only for interiors but also for exteriors. It does not deteriorate from ultraviolet rays like resin products, and maintains its high design quality throughout the life cycle of the building, aiming to reduce total costs by extending the renovation period.

Transparency Control

Wire art has a wide variety of aperture ratios. Metal screens are increasingly being used as sunshades in the West, where environmental awareness is high, and are also effective in Japan, where there are large temperature differences and seasonal changes. They can be used for a variety of purposes, including blocking the western sun, controlling line of sight, and crime prevention.

Metal screens with various wire diameters and pitches are available to suit the designer’s desired design.
The opening rate can be freely controlled to suit a variety of uses, including privacy, sun protection, and wind protection.

Global procurement of metal screens -Advanced sun and wind shield designs at standard prices-

Many designers have already come into contact with the innovative designs of stainless steel mesh and wish to incorporate it into their own projects, but in many cases the high product price is a bottleneck and prevents adoption. By sourcing globally while keeping a close eye on quality and productivity, we will expand the possibilities of metal screens in the architectural field.

An evolved version of twill weave, achieving both high particle capture rate and low-pressure lossThis amazing screen has a high foreign object capture rate while having lower pressure loss and better “escape” than regular twill weave. The complex cross-sectional structure of the screen allows the initial performance of the screen to be maintained for a long time.
The dimensions and shape of the gaps, which are made up of horizontal and vertical lines, are controlled by advanced woven wire mesh manufacturing technology. The cross-section through which the particles pass is not a typical isosceles triangle, but an equilateral triangle that maintains the highest strength, and is resistant to the tearing and opening of the screen caused by particles.

Twill weave with tightly packed wefts.
The most dense and durable woven wire mesh that can withstand high pressure.

The plain weave with tightly packed horizontal lines
enhances durability, while the three-dimensional structure provides high capture performance at high speeds.

This is a weaving method that balances the vertical and horizontal lines of the Hi-Flo
plain tatami weave to an extreme degree. The thick vertical lines ensure strength, while the horizontal lines are made very thin, achieving high permeability, as the name suggests. It is suitable for use in environments where you want to increase the capture rate without increasing pressure loss.

Origin of Woven Wire Mesh in Japan

The origin of woven wire mesh in Japan is believed to date back to the Asuka period when it was used in the construction of temples and shrines. Later, it began to be used in agriculture for farming tools. In the Genroku era, craftsmen started hand-weaving wire mesh using special tools, producing small quantities due to the high craftsmanship required.

During the Meiji period, industrial development and the introduction of foreign technology led to the production of wire mesh with hand looms. By the early Taisho period, the first mechanical looms were created, and Ishikawa Wire Mesh began manufacturing and selling wire mesh around this time.

After World War II, the applications of wire mesh expanded with the development of synthetic resins and semiconductors. Wire mesh became crucial for filtering dust from the air, purifying water, and various other filtration and classification tasks for liquids, gases, and solids.

Specifications of Woven Wire Mesh

Mesh (Mesh)

The unit “mesh” indicates the size of the openings in the mesh. It represents the number of openings along one side of a 25.4mm (1 inch) square. The higher the mesh number, the finer the openings. For reference, common household insect screens are 16-18 mesh. Generally, as the mesh number increases, the unit price per square meter of the wire mesh also rises.

Wire Diameter (Wire Diameter)

The diameter of the wire. The value of the aperture and the mesh number change according to the wire diameter. Common household insect screens have a wire diameter of 0.2mm. Generally, as the wire diameter decreases, the unit price per square meter of the wire mesh increases.

Aperture Width (Aperture Width)

The distance between wires is called the “aperture width,” representing the size of the mesh openings. The distance from the center of one wire to the center of the adjacent wire is called the “pitch.” Pitch length = aperture width + wire diameter. The proportion of open space in the mesh is referred to as the open area ratio (void ratio). It is expressed as: Open area ratio (%) = 100 × (aperture width ÷ pitch)^2.

Even if the open area ratio is the same, the aperture width can vary, so when selecting wire mesh, it is generally chosen based on mesh and wire diameter values rather than the open area ratio.

Types of Woven Wire Mesh

Plain Weave Wire Mesh

The vertical and horizontal wires intersect each other alternately at regular intervals. It is used as a standard wire mesh.

Twill Weave Wire Mesh

The vertical and horizontal wires pass over and under each other in pairs at regular intervals, allowing the use of thicker wires due to the larger bend angles.

Herringbone Weave Wire Mesh

This weave alternates the twill pattern at regular intervals to maintain symmetry.

Flat Top Weave Wire Mesh

The vertical wires remain at regular intervals, while the horizontal wires are closely placed, creating a pattern similar to tatami matting. Typically, thicker vertical wires are used, providing high strength.

Twilled Dutch Weave Wire Mesh

Similar to the plain dutch weave but with a twilled pattern, offering double the strength due to the closely packed horizontal wires.
