Injection molding process parameters
Injection molding temperature is an important factor affecting injection pressure. The injection molding machine barrel has 5 to 6 heating sections, each of which has its own suitable processing temperature (for detailed processing temperatures, please refer to the data provided by the material supplier). The injection temperature must be controlled within a certain range. The temperature is too low, the melt plasticization is poor, affecting the quality of the molded parts, increasing the difficulty of the process; the temperature is too high, and the raw materials are easily decomposed. In the actual injection molding process, the injection temperature is often higher than the barrel temperature, and the higher value is related to the injection rate and the performance of the material, up to 30 °C. This is caused by the high heat generated by the shearing of the melt as it passes through the injection port. In the mold flow analysis, the difference can be compensated in two ways, one is to try to measure the temperature of the melt-to-air injection molding, and the other is to include the nozzle in the modeling.
