The temperature of the mold in the process of injection molding directly affects the dimension precision, appearance, internal quality and production efficiency of the injection molding products. Therefore, the importance of mold temperature can be seen. So, how to adjust the mold temperature during injection molding?

1. temperature regulation system is required for injection molding to meet the requirements of product temperature. Temperature regulation system can be divided into two types: cooling system and heating system according to different situations. Generally, the temperature of plastic from injection molding to mold is about 200 degrees, while the temperature of the injection molding parts taken out of the mold cavity is below 60 degrees.

2. after injection molding, thermoplastic must cool the mold effectively, so that the heat of plastic can be transferred to the mold quickly, so that the injection molding parts can be demoulded as soon as possible after cooling.

3. for those plastics with low viscosity and good fluidity, such as polyethylene, nylon and polystyrene, if the side walls of injection molding parts are relatively thin, the mold can be cooled naturally. If the edge wall of injection molding mold is relatively thick, it needs to be cooled manually, so that the injection molding parts can be set as soon as possible and the production efficiency can be improved.

4. the temperature of each stage of injection mold needs to be monitored by injection molding personnel. It is necessary to master the method of temperature adjustment of heating and cooling system to mold. Only by strict control can the injection molding process be smoothly carried out and qualified products can be produced.

Through the above contents, we should also know how to adjust the mold temperature during injection molding. Of course, the mold temperature in injection molding is not only a decisive factor with product design, mold design and manufacturing, but also has a great relationship with the setting of injection molding process conditions.
