, including filament cracks on the surface of the parts, microcracks, whitening, cracking, and cracking time due to adhesion of parts, adhesion or traumatic failure of flow paths, cracks and cracks, mainly the reason:
Deal with:
1. If the processing pressure is too large, the speed is too fast, the more filling, the injection and holding time is too long, the internal stress is too large, and cracking occurs.
2. Adjust the mould opening speed and pressure to prevent demoulding cracking caused by rapid drawing of the workpiece.
3. Appropriately increase the temperature of daily necessities mould, make the parts easy to demould, properly reduce the temperature of the material, and prevent decomposition.
4. Prevent cracking caused by deterioration of the weld due to plastic degradation caused by plastic degradation.
5. Proper use of the release agent and attention to the elimination of substances such as aerosols adhering to the surface of the daily necessities mould.
6. By eliminating the internal stress by annealing heat treatment immediately after moulding, the residual stress of the component can be reduced, thereby reducing the generation of cracks.
