In processes such as bending, drawing, and punching with presses, recent trends have shown that issues like the occurrence of galling and scratches have become problematic due to improvements in processing levels and an increase in difficult-to-process materials. In such circumstances, we have developed a coating film that maintains formability and enhances mold life.

• Press Dies

PVD-coated films have a hardness that surpasses that of superhard materials and excellent wear resistance. On the other hand, regarding corrosion resistance, while being ceramic in nature, it is inherently superior to metals; however, if there are defects in the film, they can become starting points for corrosion, leading to deep pitting. "SX-CRS" has successfully eliminated almost all of these film defects by adopting a new process, achieving corrosion resistance that significantly exceeds that of conventional coated films.

• Plastic Mould

While retaining the advantages of the PVD method, we have developed a coating called "VSX-V" that combines lubrication and toughness, which has been difficult to achieve until now, by innovating the components and their composition. It has been confirmed to be effective in cold forging spline forming and hole punching. Additionally, by combining it with radical nitriding, we have improved surface pressure resistance and extended its lifespan.
