We propose PVD coatings that meet your needs and challenges. Achieving thick and high-hardness film formation. Various applications for parts, materials, and molds.
Our company specializes in "PVD coating," which is useful for corrosion and wear prevention of parts and molds, as well as improving release properties. We offer custom-made thick film deposition up to 50μm. By adopting a new type of evaporation source, we have achieved hard thick film molding. This expands the range of applications and further enhances wear resistance and durability. 【Effects and Examples of Applications】 ◎ Improved erosion resistance Example applications: Impellers, outboard motors, pumps, screws ◎ Improved cavitation resistance Example applications: Blades, pumps, water jets ◎ Improved sand wear resistance Example applications: Molds, conveyors, gears, jigs *For more details, please refer to the materials.

basic information
<About Custom-Made Coatings> In recent years, PVD processing has made remarkable advancements due to the development of contained elements and improvements in film deposition technology. In particular, the hardness of the coatings has significantly progressed as a result of advancements in the materials being processed and cutting machines, achieving substantial improvements as needed. For coatings used in molds and tools, hardness levels of over Hv3500 are now common, and for DLC used in components, levels exceeding Hv7000 have also been observed. However, as film hardness increases, there is a tendency for film thickness to decrease in inverse proportion. This is due to film delamination caused by stress, which can be seen as a trade-off for increased film hardness. Nevertheless, film thickness is a very important factor for wear resistance and durability. Therefore, our company offers custom-made solutions with our unique technology that allows for thicker coatings with high hardness, overcoming the trade-off that previously made it impossible to achieve thick and high-hardness PVD coatings. *For more details, please refer to the materials.
