Non-magnetic 0.002mm Coaxiality Cold Heading Dies Bushing Punch for Precision Stamping in Automotive Electronics

0.002mm Coaxiality Cold Heading Dies Bushing Punch For Automotive Electronics Stamping

Introduction:

The bushing punch adopts 94% tungsten carbide matrix (YG15 grade), with 92HRA body hardness + deep cold strengthened toughness, breaking through the bottleneck of edge breakage and deformation of traditional Cr12MoV mold steel, and achieving the ultimate match of ≤0.003mm gap between the guide bushing and the punch in 0.1mm precision blanking.

Performance-benchmark:

Precision-stamping:

Automotive core components
- Seat belt buckle progressive die (0.8mm thick 65Mn steel, lifespan > 5 million times)
- Engine fuel injector baffle (±0.003mm coaxiality to ensure oil hole accuracy)
- EV battery pole punching (resistant to copper-aluminum adhesion corrosion)

Electronic precision manufacturing
- Type-C interface terminal (0.2mm thick phosphor bronze, burr < 5μm)
- Mobile phone SIM card tray (12-station progressive die main punch)
- Relay silver contact (anti-arc ablation)

Home appliance wear-resistant parts
- Air conditioner fin multi-row hole punching (0.1mm thick aluminum foil, 20 holes/second)
- Washing machine reducer ratchet (hardened steel HRC50 continuous stamping)
