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).
