Custom Precision Parts - Terminal Forming Punches

Terminal forming punch is mainly used as forming tooling in the manufacture of precision electronic connectors. It ensures that metal terminals meet specific shape and dimensional requirements through plastic deformation.

Pain Points：
– Insufficient Machining Accuracy: Insufficient precision in the forming areas leads to poor shaping, affecting the overall performance of the terminals.
– Wear of Punch Heads: During use, the forming areas are easily worn due to frequent impacts, reducing the service life of the punches.

Solutions：
* Precision Machining: Use high-precision Seibu CNC Wire EDM (Electrical Discharge Machining) to achieve a machining accuracy of ±0.002mm in the forming areas.
* Material Selection: Use Wear-Resistant PM23 Powder Metallurgy Steel, enhancing durability.
* Heat Treatment: Implement a combination process of vacuum hardening and subzero treatment to stabilize the hardness of parts at HRC 64-66.
* Surface Treatment: Apply a TiCN (Titanium Carbonitride) coating for improved wear resistance.

Benefits：
The terminal qualification rate is increased from 85% to 99.5%.
The wear rate is reduced by 57%, and the overall life of the metal punch is increased to 50%.
