We have been operating vacuum heat treatment as our main business since 1973, quenching, annealing and applying specialized treatment on various types of parts for wide range of steels.
We can satisfy the needs of our customers with years of experience and our original heat treating techniques, not to mention product management.
We own the largest-class vacuum heat treatment furnaces in Japan to handle products up to 1,300 mm in height, 1,300 mm in width, 1,650 mm in depth and 1,500 kg/gross in capacity.
These large vacuum heat treatment furnaces can handle mass-produced parts and lead to lower costs. We own 18 heat treatment furnaces to handle various types of heat treatments with shorter delivery time.

|SUS-304||Solution treatment of a large product||500ｔ×500ｗ×1,300L|
|SUS-420J2||Quenching/tempering a large round product||⏀1,130×400ｔ|
From cleaning to heat treatment, all steps are processed in a vacuum environment of our company.
The advantages of treating in a vacuum environment include the superior capacity to remove dirt and oil on products by repeated vapor degreasing inside a furnace during the cleaning process.
We use non-polluting cleaning solutions to protect the environment.
In the heat treatment process, this prevents the formation of harmful coloring, oxide scale and decarburization.
Also, superior brilliance, stable hardness and small dimensional changes are its characteristics.
