Production standards:
High coating adhesion, no spalling of coating, no micro chipping of cutting edge, Five inspections to ensure production standards.
Five inspections:
→1. Mixed material inspection. → 2. Blank inspection after pressing. →3. Blank inspection after sintering.
→4. Blank inspection before coating. →5. Full inspection of finished product after coating
