[Product Details | Terminals & Contacts - Precision Pressed Copper/Steel Parts]

Product Positioning

Provide terminals and contact pieces with high conductivity, high elasticity and high reliability for connectors, relays, switches, sensors, etc. The materials include brass (C2680/C2600), phosphor bronze (C5191/C5210), stainless steel (SUS301/304), etc., with thickness ranging from 0.05 mm to 1.2 mm.

2. Core Processes

• **High-speed Precision Pressing**: 25 T - 125 T servo presses with a step accuracy of ±0.01 mm, single-piece cycle time 120 - 300 pcs/min.

• **Multi-station Progressive Die Design**: Independently developed multi-station progressive dies, integrating pre-punching, flanging, spring-clip bending, and shearing for simultaneous completion, reducing secondary processes.

• **Online Inspection**: CCD vision + laser thickness measurement + pressure curve monitoring, 100% full inspection, defect rate ≤ 50 ppm.

• **Surface Finishing**:

‑ Copper parts: Nickel plating 1.27 µm + Tin mist coating 2.54 µm, salt spray test for 96 hours without rust;

‑ Steel parts: Nickel base plating + Gold plating 0.05 µm, contact resistance ≤ 1 mΩ.

3. Key Parameters

• **Tolerance**: Shape ±0.02 mm, Hole Position ±0.01 mm;

• **Elastic Life**: Insertion and Ejection ≥ 5000 times, Force Degradation ≤ 10%;

• **Conductivity**: Copper Parts ≥ 85% IACS, Surface Gold Plating of Steel Parts Increases Conductivity by 30%;
