Causes of cracking of Robot Micro Screws

1. Excessive local tensile stress During the processing, due to excessive local tensile stress, Robot Micro Screws will be affected by internal stress and external impact, resulting in local bulging deformation and cracking.

2. Inadequate molding process parameters During the part forming process, the concave die, the pressing core and the parts of the two must fit closely together. When the machine tool slide slides down, the plastic deformation of the hardware plate is pressed to achieve forming. The processing technicians failed to adjust the machine tool pressure in time according to the prescribed process requirements at this stage, resulting in unstable work and cracking of Robot Micro Screws.

3. Flanging forming mold design defects This mold is common for an Robot Micro Screws with dual cavities and left/right components.

Since the process has both flanging and forming content, and the parts are special and complex, the bending surface is narrow, and the molding requires the concave mold core to be consistent with the molding surface, the Robot Micro Screws structure molding stroke is large, the pressing area is small, and there is cracking.
