Yellow TiN Coating Punch Rod High Hardness Stretch Punch for Metal Forming Die Tool Parts
- Premium TiN Yellow Titanium Coating
Uniform bright golden TiN coating, ultra-low friction coefficient, effectively reduces material adhesion during stretching processing, less product scratch and mold sticking. Excellent wear & oxidation resistance, extend service life significantly.
- Super High Hardness Substrate Material
Made of high-speed steel / carbide base, precise CNC grinding, stable mechanical performance, withstand heavy load, repeated high-speed stamping and stretching without deformation.
- Precision Dimensional Tolerance
Mirror smooth surface without burrs, strict concentricity control, consistent size batch to batch, guarantee stable forming quality for thin metal stretching, deep drawing operations.
- Optimized Stretch Punch Structural Design
Step integrated structure specially customized for deep drawing, stretching, flanging molds. Smooth transition surface, avoid workpiece cracking, improve finished product yield.
- Long Service Life & Cost Saving
TiN coating drastically lower mold maintenance frequency, reduce downtime and replacement cost, ideal for mass production stamping factories.
- Wide Industry Compatibility
Widely used in auto parts, hardware fittings, electronic component, kitchenware deep drawing molds; support custom diameter, length and step sizes.
- Quality assured: strict inspection, stable export
- Non-standard custom: made to drawings, flexible
- Fast delivery: in stock, reliable lead time
- Professional service: 20+ years, full support
