This is a treatment method that infiltrates carbon/nitrogen. We will make optimal proposals by utilizing our extensive equipment lineup and the experience we have cultivated.

This is a treatment method that infiltrates nitrogen/carbon. Using our own know-how, we have succeeded in reducing the porous layer by up to 30%.

This is a method in which metal filler metal is brought into a molten state and joined by capillary action. Stable quality can be maintained by processing in a vacuum furnace.

This is a press quenching method that takes advantage of the expansion during martensitic transformation after heating steel to austenitization and quenching it in oil. We mainly produce bearings.

Using special equipment, we can produce thin roll shapes that cannot be produced using batch furnaces through solid solution treatment, normalizing, and annealing.

DLC stands for Diamond-Like Carbon, and this coating provides high tribological property. We develop and provide various coating films according to the needs of our customers.

PVD coating (Physical Vapor Deposition) is roughly classified into chromium and titanium. A coating film containing chromium as the main element produces excellent sliding properties in oil,and has high hardness and heat resistance by adding other elements.

PVD coating (Physical Vapor Deposition) is roughly classified into chromium and titanium.Coating films containing titanium as the main element have excellent heat resistance and high hardness, and the addition of other elements extends the characteristics further.

We have newly established the OIC area as a place to create new value using the latest technology and ideas centered on dry coating processing.

The Innovation Division promotes joint development and joint work to develop technologies that meet market needs.
