Functional Surface Modification PVD coating processes Tribec™
The Tribec™ coatings are functional surface modifications applying hybrid PVD technologies.
- The pursuit of high abrasion resistance, excellent lubricity and heat resistance requirements of various dies and forming tools, we established the original hybrid PVD technologies with laminated functional layers.
- This process realized higher film adhesion by the most suitable pre-treatment and cleaning.
- We developed multi-functional PVD coating processes “Tribec™” by combination of different characteristics designed for various dies and punches.
We propose a method to use materials tailored to your company.
