Heat Treatment

Gas Quenching/Tempering Furnace

It is possible to heat-treat parts by using vacuum heat treatment equipment while maintaining brilliance of the surface of the parts.
It is also possible to obtain uniform carburization in the inside of fine holes and blind holes by using a vacuum carburizing furnace.

Surface Treatment

Surface Treatment 6 Color Sample

We can perform various surface treatments, including a hexavalent chromium-free chemical conversion coating, for which we first acquired Nadcap certification in Japan. In addition, we are working on an environmentally friendly approach, reusing more than 80% of the water used in the treatment through an ion exchange wastewater treatment system.
