Analysis And Solution Of Cracking In Injection Molding
Cracks, including filament cracks, microcrack, whitening, cracking on the surface of parts, as well as cracks and fracture time due to component adhesion, flow path adhesion or traumatic damage. The main reasons are as follows:
Processing:
(1) Excessive processing pressure, too fast, the more filling materials, injection, holding pressure for too long, will cause excessive internal stress and cracking.
(2) Adjust the speed and pressure of mold opening to prevent the quick and strong drawing parts from causing demoulding cracking.
(3) Adjust the […]
