Product advantages
1. Extended Tool Life Wear Resistance Utilizes premium tungsten carbide substrates with TiAlN coatings, extending service life by 200-300% vs conventional dies. Maintains ≤0.005mm dimensional drift over 1M+ cycles for sustained precision. 2. High-Speed Production Capability Enables 300-500 parts/minute output with integrated cooling channels minimizing thermal deformation. Quick-change die systems reduce setup downtime by 70% for flexible batch production. 3. Material Efficiency Cost Savings Achieves 99% material utilization via optimized grain flow design, reducing scrap costs by 40%. Compatible with low-to-high carbon steels, stainless alloys, and non-ferrous metals (Cu, Al).
