In the injection molding process of plastic products, whether it can be cooled in time and effectively will directly affect the finish and pass rate. If the plastic container cannot be cooled and shaped in the production process, the produced container will not be full, the wall thickness will be uneven, and the color will not be bright, resulting in low product quality.In the production of packaging film, cold water or cold air cooling molding is required to produce a qualified product. If you use a chiller to cool, it not only greatly improves the quality of the product, but also improves production efficiency.
