Company information
By adopting special sputtering and plasma CVD processes, we provide high-quality coatings with excellent adhesion even at low-temperature treatments below 180 degrees, along with high film thickness precision and outstanding tribological properties such as wear resistance, seizure resistance, and low friction coefficient, all based on abundant achievements and experience, with short delivery times. In particular, coatings from the Seltes brand, such as CrN-based coatings (Seltes X, N) as alternatives to Cr plating and Seltes DLC, which have excellent adhesion even under high surface pressure, are highly regarded in plastic molding molds, press molds, automotive parts, and high-precision sliding components. We also conduct various evaluations of metal surfaces and thin films, as well as defect analysis, using surface cleanliness measurement instruments like Corona Surf.
