If the surface temperature of the mold does not reach the appropriate temperature, the surface of the product will be dim and very rough, and the surface quality cannot meet the requirements. High mold temperature can make the product better copy the mold surface.
If the mold temperature is relatively low, the injection material is not easy to form or is not easy to fill. If the mold temperature is too high, the injection of molten material will not be easy to cool and set, products are also prone to sag deformation and burr.
In addition, due to the crystallization effect, the shrinkage of some plastic products will occur after days or weeks, which is not only related to the surface temperature of the mold but also related to the storage conditions of the products.Tags: mold temperature
