Cold Pressing And Cold Heading Can Improve Fatigue Performance.

For component female crimp contact, which forms the basis of the part, the manufacturing process involves cold heading, where the internal structure of the material maintains continuous grain flow during plastic deformation. Due to the absence of cutting damage, the metal's lattice structure and material density remain intact, and this continuous grain flow results in a more stable mechanical response.

Cold heading equipment uses multi-station, multiple stamping or extrusion processes to progressively shape the billet into the final structure. Each deformation step is performed at room temperature, without introducing thermal stress and reducing metallurgical defects.

The resulting component male crimp contact undergoes deformation strengthening and grain flow reconstruction of its internal metal structure. Compared to traditional cutting or hot forging methods, this process makes the part less prone to crack initiation points under repeated loads, resulting in better fatigue life.
