Injection Molding and Temperature Nov 08, 2018
Based on the grade you are using, checking the coefficient of linear thermal expansion. It will depend on which stage your weld lines are formed. If you have a high molecular weight material and the weld area is during the initial stages of filling, the weld strength may be good in both climates. If your weld area is towards the end of filling, a grade with higher elongation property m...

The solution of bubble issue during injection molding process Nov 23, 2018
According to the causes of bubbles, the countermeasures are as follows: (1) When the wall thickness of the product is large, the cooling speed of its external surface is faster than that of the central plastic part. Therefore, as the cooling goes on, the resin at the central part shrinks and expands towards the surface, resulting in insufficient filling at the central part. This condition is calle...
