In plastic mold manufacturing, temperature control of the mold is very important. If the cooling system design is not reasonable, internal stress will be generated for small plastic parts, and deformation and even stress cracking will be caused for thin-walled large plastic parts. Moreover, insufficient cooling can lead to prolonged injection molding cycles, thereby reducing production efficiency. Therefore, the importance of plastic mold water transportation design is self-evident.

In order to provide plastic molds with the mold temperature required for plastic molding, improve the fluidity of plastic materials, facilitate the filling of mold cavities, and ensure the quality of plastic products, it is necessary to effectively remove heat in order to quickly cool and solidify the molten resin filled in the mold cavity after filling. The design of plastic mold water transportation in this way aims to form a very short molding cycle time.

The purpose of cooling plastic molds:

1) Balanced cooling to improve the quality of plastic products;

2) Effective cooling to shorten the injection molding cycle;

3) Institutional cooling ensures the normal operation of plastic molds.
