Glass-like carbon coating is a technology that forms a coating layer of glass-like carbon by heating up graphite material coated with a proprietary resin. This technology can be used to coat parts for semiconductor manufacturing systems to reduce particle generation from the parts. 【Features】 ・Reduces dust generation of graphite materials. ・Permeating not only the surface of the graphite material but also the inside. ・Reduces the generation of gas from graphite materials. ・Reduces gas permeation of graphite materials. ・Capable of handling various shapes of graphite materials. ・Reduces reaction with metal and glass. *For more details, please contact us.*

DLC (diamond-like carbon) coating deposits a low-friction DLC film using plasma ion implantation coating method. 【Features】 ■Capable of handling work with complicated shapes ・By using the work itself as a source of plasma, plasma is formed along the shape of the work and allows gas to flow around and deposit a film on complicated shapes and interiors. ■Excellent lubricity ・Excellent lubricity due to the formation of low coefficient of friction film ■Can deposit on resin and rubber as well as metal and aluminum. ・Low-temperature deposition is possible. ■Can deposit with the flexibility to follow the shape of the base material (even resin is resistant to film peeling). *Please contact us if you have any problems with life reduction due to friction of parts. *We can provide technical explanations and trial production. *We also sell DLC deposition system. * For more details, please contact us or download our catalog for more information.
