cool of plastic mold
The plastic mold can be viewed as an exchanger that carries the heat of the hot melt away from the plastic mold by the circulating refrigerant. The role of the cooling system 1. Improve productivity 2. Ensure the effective of a mold In the whole cycle of thermoplastic injection molding , the mold cooling time accounts for more than two-thirds of the entire cycle . An effective cooling circuit design reduces cooling time, and therefore increase total production; in addition, uniform cooling reduces residual stresses due to uneven heat transfer. Thereby even cooling would control the warpage of the finished product to maintain the accuracy and stability of the size,and improve the quality of the product. The goal of cooling Balanced cooling (improved product quality) Effective cooling (increased productivity) In the design of the mold cooling system , in addition to considering the shape of the molded product, the mold structure and other factors, designer can determine th
