Model: Entrance Packing
What is Entrance Packing?
It is a water-stopping rubber used for shielding and propulsion work. We sell about 20,000 pieces of entrance packing per year.
The first propulsion work in Japan was carried out in 1948, and our entrance packing has walked the same history as the history of propulsion work. Please try the best of this technology.
Entrance Packing Physical Properties Table
It is a rubber made for entrance packing by our company’s unique formulation.
The strength is different from general-purpose rubber plates.
| material | Hardness (HA) | Tensile strength (MPa) | Elongation rate (%) | forte |
|---|---|---|---|---|
| KE-A | 50±5° | 22 or more | 600% or more | Top specification entrance packing. |
| KE-M | 60±5° | 15 or more | 500% or more | Our standard packing. Even at sites with a lot of water. |
| KE-N | 55±5° | 7 or more | 350% or more | Wear-resistant rubber uniquely formulated for normal propulsion. |
Tensile test of KE-A
Tensile test of KE-M
* Compare the tensile strength of the rubber in the arrow part.
A word from the person in charge In recent years, there has been an increase in propulsion work on deep and poor ground, and I think that we are often troubled by groundwater and rubber damage.
In such a case, why don’t you try our KE-A and KE-M packings? I am sure you will be satisfied.
Production flow
Let’s take an example of the production of oval-shaped packing with an outer diameter of 2 m or more.
* The product manufacturing process varies depending on the shape and dimensions of the packing.
(1) CAD drawing
We will check the drawings and CAD data received from the customer.
(2) Creation of a template
Send the data in (1) to the plotter and create a template.
Creating
Finished template(3) Manufacture of fan-shaped packing
Vulcanize the packing in a mold with approximate dimensions.
Before vulcanization
After vulcanization(4) Joints
We will process the fan-shaped packing produced in (3) to join it. After that, the fan-shaped packing is integrated with a vulcanized joint. (Small caliber is integrated)
Machining joints
Before Joint
After Joint(5) Processing (cutting, etc., final finishing)
Match the template in (2) to the packing jointed in (4) and cut it. It will be the same as the packing drawn in (1).
(6) Completion
If you look at it from above, you can see that it is an ellipse.
