Professional Grade Tungsten Carbide Notching Punch with Extreme Wear Resistance and High Precision
The Tungsten Carbide Notching Punch is an industrial-grade consumable designed for high-load, high-precision stamping operations. Manufactured from premium tungsten carbide (hard alloy), it is renowned for its unparalleled hardness, exceptional wear resistance, and extended service life.
This product is widely used for the rapid and precise blanking and shearing of metal materials such as stainless steel plate, alloy steel, silicon steel sheets, copper, and aluminum. It is an indispensable tool in industries including hardware stamping, electronics and electrical appliances, automotive components, and mold manufacturing.
The superior performance of our product stems from the unique properties of the tungsten carbide (hard alloy) used. The table below provides a detailed comparison of key performance indicators:
| Performance Indicator | Tungsten Carbide (Hard Alloy) | High-Speed Steel (SKH51) | Tool Steel (Cr12MoV) | Performance Advantage |
|---|---|---|---|---|
| Hardness | HRA 90-92 | HRC 63-65 | HRC 58-60 | Significantly harder than tool steels, providing fundamental wear protection and minimal abrasion. |
| Density (g/cm³) | 14.0 - 14.5 | ~8.2 | ~7.7 | High density, pore-free structure, uniform material, excellent stability. |
| Transverse Rupture Strength (MPa) | 3500 - 4000 | ~3000 | ~2000 | Combines high strength with toughness, excellent resistance to bending, prevents chipping and breakage. |
| Elastic Modulus (GPa) | 600 - 630 | ~220 | ~210 | Exceptional rigidity, minimal deformation under high pressure, ensures stamping precision. |
| Coefficient of Thermal Expansion (10⁻⁶/℃) | 5.0 - 5.5 | ~11.0 | ~11.5 | Excellent thermal stability, minimal dimensional change under heat from continuous stamping. |
| Thermal Conductivity (W/m*K) | 80 - 110 | ~30 | ~30 | Superior heat dissipation, rapidly carries away stamping heat, protecting the punch and extending life. |
Note: The above parameters are typical values; specific values may vary slightly depending on the alloy grade and process.
- Selected Material: Made from high-quality fine-grain tungsten carbide powder, formed by high-pressure sintering, ensuring a uniform and dense microstructure for consistent performance.
- Precision Edge: The notching profile (special-shaped punch head) is precision ground, ensuring accurate contours and sharp edges for flawless performance in every stroke.
- Strict Tolerances: Tight control over outer diameter, length, and all other dimensional tolerances guarantees perfect fit within the die, reducing play and prolonging die life.
- Surface Treatment: Optional precision polishing or special coatings are available for specific models to further reduce the coefficient of friction and improve anti-adhesion and corrosion resistance.
- Electronic Components: Stamping and forming of lead frames, precision connectors, and carrier tapes for chips.
- Automotive Industry: Piercing and blanking of precision parts for pistons, transmissions, airbags, etc.
- Home Appliance Manufacturing: Blanking of internal metal structural parts for microwaves, air conditioners, washing machines, etc.
- Hardware & Tools: Blanking and forming of saw blades, cutter heads, and various hardware products.
