Injection molding is also a separate engineering technology. Its purpose is to transform the raw materials of thermoplastics into products that can be used and maintain the original performance through the important process conditions of injection molding.
Injection molding is also a separate engineering technology. Its purpose is to transform the raw materials of thermoplastics into products that can be used and maintain the original performance through the important process conditions of injection molding. Therefore, the preparation of the process parameters of injection molding is an important link to ensure the injection molding process. In the preparation of injection molding process parameters, we should pay special attention to the following factors: temperature, pressure and time.
Injection temperature control: the temperature to be controlled during injection molding process includes barrel temperature, nozzle temperature and mold temperature. The main purpose of barrel temperature and nozzle temperature control is to fully plasticize and flow the materials in the barrel.
The purpose of mold temperature control is to improve the fluidity of molten materials during mold filling and help molten materials fill all parts of the mold cavity quickly. The other is to make the materials filled with the mold cavity fully cooled and shaped at constant temperature. Thirdly, the control of mold temperature has a great impact on the internal performance and apparent quality of products.
