Surface Strengthening Of Cold Pressing Needles

After processing, crimp socket contact typically faces complex usage environments, placing higher demands on female crimp contact surface condition. The material surface is the first area to be affected by mechanical loads or assembly friction conditions, therefore male crimp contact surface strengthening treatment becomes an important link in the production chain. Through surface modification techniques, such as surface hardening, shot peening, or polishing, the surface microstructure of the material can be altered at the microscopic level, improving its surface morphology and microstructure.
