Why you want to control the temperature of the mold

When the injection molding machine is working, we use the mold temperature control machine to control the mold temperature. What is the purpose of controlling the temperature? In fact, if you think about it, you will know the answer. This problem is not difficult. In the process of injection molding, the mold temperature will rise, and too high temperature will affect the injection molding process, so the temperature must be lowered and kept within a certain range. If the temperature is too high or too low, it is not a good thing. If the mold can be heated to the working temperature and the mold temperature is kept constant at the working temperature, the cycle time can be optimized to ensure the stable and high quality of the injection molded parts.

We also need to understand that the mold temperature affects the surface quality, that is, if temperature control is not performed, the surface quality will be affected, such as fluidity, shrinkage and injection cycle. What happens when the mold temperature is too high, or when the temperature is low? Different materials can have different effects. For thermoplastics, a higher mold temperature usually improves surface quality and fluidity, but it will increase the cooling time and injection cycle. A lower mold temperature will reduce shrinkage in the mold, but will increase the shrinkage of the molded part after demolding.

For thermoset plastics, a higher mold temperature typically reduces cycle time, and the time is determined by the time required to cool the part. In addition, in the processing of plastics, a higher mold temperature will also reduce the plasticizing time and reduce the number of cycles.
