How to adjust mold temperature during injection molding

Whether the mold temperature is appropriate during the injection molding process will directly affect the dimensional accuracy, appearance, internal quality and product production efficiency of the injection molding products. This shows the importance of mold temperature. Then, how to adjust the mold temperature during injection molding?
1. Injection molding requires a temperature regulating system to meet the product temperature requirements. The temperature regulating system can be divided into cooling system and heating system according to different conditions. Generally, the temperature of the plastic injected into the mold is about 200 degrees, while the temperature of the injection molded part when taken out of the mold cavity after molding is below 60 degrees.
2. After the injection molding of thermoplastic, the mold must be effectively cooled, so that the plastic heat can be quickly transferred to the mold, so that the injection molded parts can be demoulded as soon as possible after cooling.
3. For those plastics with low viscosity and good fluidity of molten plastics, such as polyethylene, nylon and polystyrene, if the side wall of the injection molded part is thin, the mold can be naturally cooled. If the side wall of the injection molding tool is relatively thick, it needs to be cooled manually to make the injection molding parts shaped as soon as possible and improve the production efficiency.
4. The temperature of the injection mold at each stage needs to be monitored by the injection molding personnel, who should be familiar with the methods of the heating and cooling system to adjust the temperature of the mold. Only by strict control can the injection molding process be carried out smoothly and qualified products be produced.
From the above, we should have a general understanding of how to adjust the mold temperature during injection molding. Of course, the mold temperature during injection molding is not only a decisive factor in product design, mold design and manufacturing, but also has a great relationship with the setting of injection molding process conditions.
