Applications of Our Carbide Punches and Dies
Our high-hardness, wear-resistant tungsten carbide components are engineered to withstand extreme pressures and reduce downtime in high-volume production lines:
Semiconductor & IC Packaging: Ultra-fine probe pins, test socket pins, and micro-punching pins.
Stamping & Metal Forming: Heavy-duty punches, cold heading dies, progressive die components, and draw dies.
Electronics & Connectors: Micro-punches for precision terminal connectors and PCB tooling.
Medical Device Manufacturing: High-precision micro-tooling and customized inspection jigs.
Rigorous Quality Control & Inspection Standards
To guarantee that every custom tungsten carbide punch and die meets strict engineering tolerances, 100% of our products undergo non-destructive and dimensional testing prior to delivery:
Dimensional Verification: High-magnification Optical Measurement Systems and Keyence Image Dimension Measurement Systems.
Surface Quality: Profilometers for strict Ra surface finish checking.
Material Integrity: Grade-verified raw tungsten carbide with guaranteed density, hardness (HRA 88–93), and fracture toughness.
Frequently Asked Questions
Q1: What tolerances can you achieve on micro tungsten carbide punches and dies?
A: We consistently achieve outer/inner diameter tolerances within ±0.001mm, with minimum pin diameters down to φ0.1mm and mirror polish surface finishes of Ra 0.05μm .
Q2: Can you manufacture custom tungsten carbide punches based on CAD drawings?
A: Yes. We accept DXF, STEP, IGES, and PDF technical drawings to manufacture fully customized carbide punches, dies, jigs, and probe pins according to your exact dimensional requirements.
Q3: What are the benefits of tungsten carbide over tool steel for punches and dies?
A: Tungsten carbide offers significantly higher wear resistance, hardness (HRA 88–93), and compressive strength compared to traditional tool steels (like D2 or M2). This dramatically extends tool life, minimizes burrs on stamped parts, and reduces production downtime.
