Hokunetsu began with mold heat treatment and has advanced its surface treatment technologies including nitriding and PVD coating to meet modern demands. With 20 years of coating experience, Hokunetsu offers optimal PVD films.
Proprietary Technologies
- diXis® Dual-Beam Arc Ion Plating: Enables ceramic film formation inside deep holes, improving durability and lifespan of molds and components. (e.g., powder compaction molds, semiconductor press-in pots)
- Ultra-Smooth PVD Coating: Reduces surface roughness and improves galling, corrosion, and release issues in cold forming. (e.g., cold forging molds, copper alloy stamping)
- Composite Treatment: Radical nitriding + coating
