Exceeding the material deformation limit for Precision Electronics Micro Screws

2025,08,22

1. Poor surface quality of Precision Electronics Micro Screws materials—scratches cause stress concentration, and corrosion increases resistance.

2. Excessive feed resistance on the extrusion surface—large billet shape, small gap between extrusion ribs and grooves, and too small die corner radius.

The outer slide is adjusted too deep, the stretching ribs are too high, and the smoothness of the Precision Electronics Micro Screws extrusion surface and die corners is poor.

3. Excessive local stretching in the Precision Electronics Micro Screws, resulting in stretching deformation exceeding the material deformation limit.

4. During Precision Electronics Micro Screws operation, the billet is placed on one side, resulting in excessive pressure on one side and insufficient pressure on the other side.

An oversized side makes feeding difficult, leading to cracking; an undersized side allows for excessive feed, resulting in wrinkling, which makes feeding difficult and causes cracking.
