As a plastic injection molding manufacturer in China, GoodTech has accumulated many years of experience in the field of plastic injection molding. There are many influencing factors in the process of manufacturing plastic injection molding parts. Now let's understand what factors affect the quality of injection molding?
Factors affecting the quality of injection molding
1. Injection pressure: In the injection molding process, the reason for using injection pressure is to offset the resistance of the molten raw material when flowing, or because the resistance when flowing needs to be eliminated by the injection pressure of the injection machine, the effect of these two pressures On the contrary, to ensure a stable filling environment.
2. Injection time: Generally, the injection time of a product is certain. A reasonable injection time is conducive to the molten raw material filling the cavity of the mold, which is of great significance for improving the surface quality of the product and reducing the product size tolerance.
3. Injection temperature: The injection temperature is generally controlled within a certain range. If the temperature is too low, it is not conducive to the plasticization of the raw materials, affects the quality of the finished product, and increases the processing difficulty; if the temperature is too high, the raw materials are easy to decompose.
