The Flowability Of Metal In The Cold Press Needle Extrusion Connection

crimp contact male Through its precise pressure distribution, it induces a localized high-temperature effect in the contact area of ​​the metal material, thereby triggering the dissolution and flow of the metal. This phenomenon occurs during the frictional contact between the metal surface and crimp socket contact. Due to the high pressure and minute deformation, the interatomic bonding force on the metal surface is weakened, resulting in localized metal dissolution.

female crimp contact The metal dissolution and flow caused by extrusion bonding is actually a controllable "fluidization" effect formed by the significant reorganization of the internal microstructure of the metal under extreme plastic deformation field male crimp contact and the restriction of the macroscopic deformation path.
