No CommentsSome plastic parts after demoulding, have swelling or bubbling on the back of metal insert or in the extra thick parts. This is due to the expansion of the released gas under the action of internal pressure on the plastic which has not been completely cooled and hardened. JasonMould works with you for details. Solutions:

Cracking is a common defect of plastic products, which is mainly caused by stress and deformation. It mainly includes residual stress, external stress and stress deformation caused by external environment. (I) cracking caused by residual stress The residual stress is mainly caused by the following three conditions, i.e. overfilling, demoulding and pushing out and metal
