cracking is a common defect in plastic products, and the main reason is due to stress deformation. There are mainly residual stress, external stress and stress deformation caused by external environment. What should I do after cracking?
1. Cracks caused by residual stress
The residual stress is mainly caused by the following three conditions, i.e. excess filling, ejection from mould and metal inlay. As a crack generated under the condition of excess filling, the prevention and control methods can be mainly started from the following aspects:
(1) Since the pressure loss of the sprue is the smallest, if cracks are mainly generated near the sprue, the multi-point distribution of point gates, side gates and shank gates can be considered instead.
(2) On the premise of ensuring that the resin does not decompose or deteriorate, appropriately increasing the resin temperature can reduce the melt viscosity... less
