Product Overview
This custom-engineered YG20 tungsten carbide punch pin is precision-designed for high-accuracy stamping and punching operations. Featuring a flat-head nail structure (shank diameter 1.7mm±0.02mm, head diameter 2.7mm±0.03mm, total length 31.5mm±0.1mm), it delivers exceptional durability in micro-hole punching, precision die-cutting, and high-wear applications. Strictly produced to client-provided drawings with full-process QC, ensuring dimensional accuracy and performance consistency.
Key Advantages
Superior Wear Resistance
YG20 alloy (80% tungsten carbide, 20% cobalt) provides Rockwell hardness HRA≥86 and compressive strength ≥3500MPa, offering 5-8x longer service life than high-speed steel tools. Micron-Level Precision
CNC grinding with laser measurement ensures ±0.02mm dimensional tolerance and surface roughness Ra≤0.2μm, ideal for automated precision tooling systems.
Optimized Geometry
1.7mm Slim Shank: Minimizes material deformation in thin-gauge sheet/film processing.
2.7mm Flat Head: Distributes impact forces evenly to prevent edge chipping.
31.5mm Balanced Ratio: Ensures operational stability while resisting deflection. Tailored Customization
Modifiable dimensions (diameter, length), coatings (TiN/TiCN), and edge treatments. Prototypes available in 5-15 days with MOQ 10pcs.
Customization Services
Drawing-Based Production: Submit 2D/3D designs for DFM analysis and optimization. Premium Finishes: Mirror polish (Ra≤0.1μm) or PVD coatings for extended lifespan. Certification: Material test reports (ISO 4499-2) and inspection certificates included.
