Developed newly ZERO-I ( Zero One) coating from the existing PVD Coating for higher hardness, heat resistance and lubricity . Superior wear resistance contributes to longer life.

Abrasion resistance, heat resistance improvement, cold press, cold forging, warm forging, punching die high-tensile press molding, FB molding, etc.


High hardness

Automobile industry, the use of molds under severe conditions such as high-tensile steel and thickening has progressed, and it has become a challenge to suppress local elastic deformation that induces film peeling. ZERO-Ⅰcleared those problems and also surpass Hv 3,500 over TiCN/TiALN has achieved high hardness.

High heat resistance

Achieves 1,000 ℃ exceeding TiAlN .
Corresponding to frictional heat oxidation and warm forging in cold forging, which causes of seizure.

High adhesion thick film

Mostly, PVD film thickness is 2~3µm, but ZERO-I has allowed both high adhesion and thick film by the stress relaxation techniques. This improves wear resistance and increases the effect of suppressing elastic deformation.

  • Film hardness: Hv3,500
  • Heat-resistant temperature: 1,000℃
  • Coefficient of friction: 0.60
  • Operating temperature: 500℃
  • Recommended film thickness: 4µm more
