Description
Cemented Carbide Mirror-Finished Polished Punch
Product Overview

In precision manufacturing, the surface quality of a punch directly determines forming accuracy and mold service life. Our Carbide Mirror-Finished Polished Punch is specifically designed for high-precision stamping, drawing, and powder metallurgy industries. Using an ultra-fine grain carbide substrate with our exclusive mirror lapping process, it retains carbide's excellent hardness while achieving an ultimate mirror effect of Ra ≤ 0.02μm (nanolevel in some cases). This effectively solves common stamping issues such as material sticking, galling, and abrasive wear.

Key Advantages
  • Nano-level Mirror Effect, Eliminates Galling: Ra 0.01μm - 0.02μm with extremely low friction coefficient prevents built-up edge
  • Superior Wear Resistance, 3-5 Times Longer Life: Hardness HRA 89-93.5 provides significantly longer service life compared to traditional SKD11 or high-speed steel punches
  • Excellent Dimensional Stability: Thermal expansion coefficient approximately 1/2 that of steel maintains micro-hole precision under high-frequency stamping
  • Edge Breakage Resistance & Toughness Balance: Bending strength ≥ 1800 N/mm² reduces the risk of chipping
Applications
  • Electronics Industry: LED lead frames, connector terminals, IC packaging molds
  • Automotive Industry: Airbag components, high-precision fuel injection nozzles, sensor housings
  • Powder Metallurgy: Press-forming of carbide components
  • Specialty Machining: High-speed stamping of motor silicon steel sheets, high-silicon aluminum alloy blanking
