Products Advantages
1. Exceptional Wear Resistance & Extended Lifespan Tungsten Carbide Base + TiAlN Coating: 300% longer service life vs. conventional steel dies. Maintains cutting-edge sharpness for over 500,000 cycles with ≤0.003mm dimensional tolerance drift. 2. Precision Cutting & Material Versatility Achieves burr-free edges (±0.01mm accuracy) for sheet thicknesses from 0.1mm to 8mm. Compatible with stainless steel, copper, aluminum alloys, and high-strength steels (HRC ≤55). 3. High-Speed Production Efficiency Supports continuous operation at 800+ strokes/minute with integrated cooling channels to reduce thermal stress. Modular design enables tool changes in ≤3 minutes, slashing downtime by 60%.
