Made in: Japan
Manufacturer: Nikkin Flux
Model: NK1700

Features

This device measures the gas content in aluminum molten metal by specific gravity, which indicates the metal’s grade. In high-quality aluminum casting, surface defects caused by residual gas holes, known as “pinholes,” represent a significant quality concern. Understanding the volume of gas contamination in the molten metal is crucial for planning the subsequent treatment, which is the degassing process.

・Able to predict the risk to get pinhole defect from Hydrogen gas.
・Measurement time is about 5 minutes.
・The exhaust flow volume and the time required to reach target pressure are adjustable.
・It is introduced at low cost.

Solidified sample by pinhole test NK1600.
The specific gravity differs depending on the exhaust flow gas volume.
By adjusting pressure reduction conditions, you can conduct solidification test under the high correlation with defect rate of your products.

Specifications

1 * Gauge unit shows the negative value in decompression side. International System of Units (SI) shows positive value ( basically in Pa) in decompression side. Mbar is used in Europe.
