Mold Structure 1. Before everything else, it will be significant to completely be aware of the specialized specifications of the plastic mold construction, steel, hardness, accuracy, and so on., which includes the shrinking amount of the resin , Three-dimensional measurement, and producing evaluation. 2. Completely think about the shrinking, flow mark, draw direction, weld line …

Rusting of plastic molds is a normal phenomenon and  caused by special reasons.It is not always due to quality problems of steel products. Melt Decomposition Some plastic raw materials will release volatile gases after being heated, which are corrosive and corrode the mold steel. Therefore, when the injection machine stops , wipe the mold clean …
