Product Description
Electronic contacts are common conductive parts in electrical equipment, the custom metal forming parts are widely used in switches, sockets and other products. Furui stamps and micro-machines electronic contacts from 0.05 mm Be-Cu or phosphor-bronze strip, coining, plating Au/Ni 0.3 µm selective, and 100 % CMM-sorting for insertion force ≤ 0.5 N. From RF spring fingers to 200 A EV power pins, we deliver > 2 million defect-free contacts monthly to Tier-1 automotive and 5-G suppliers.
Main material: Mainly H65 brass or phosphor bronze strip, thickness 0.3-0.8mm, contact pieces, springs and other parts are made by stamping.
Surface treatment: Commonly used nickel plating (3-5μm) or tin plating (1-3μm) process, some high-end products are silver-plated.
Stamping: Use high-speed punch presses with continuous mold production, and can complete 2000-5000 stampings per hour.
Forming process: The bending angle tolerance is controlled at ±2°, and complex shapes are processed through multi-station molds.
Welding method: Most of them use resistance spot welding or laser welding to ensure the stability of the contacts.
Core Performance Advantage
Conductive performance: contact resistance ≤ 20mΩ (in accordance with GB/T 5095 standard)
Durability: conventional products can withstand 5000-10000 plug-in and pull-out cycles
Corrosion resistance: nickel-plated products pass 48-hour salt spray test
Low-voltage electrical appliances: air switch contacts, relay shrapnel
Household appliances: power plug contact pieces, thermostat reeds
Automotive electronics: fuse clips, wiring harness terminals
Material utilization rate of more than 85% (through optimized layout design)
Use cyanide-free electroplating process to reduce pollution
Scrap copper recycling system achieves more than 95% metal reuse
