Temperature control plays a very important role in plastic mold processing and injection molding. It can decide whether the product is good or bad. In a big way, even if you make it to the customer, you will lose the customer’s trust in you and cause losses to the company. In a small way, it doesn’t matter. It’s a big deal to redo. Don’t do this, but you should remember that these are actually a waste of the company’s resources.
1. Barrel temperature: the temperature to be controlled in the injection molding process includes barrel temperature, nozzle temperature and mold temperature. The first two temperatures mainly affect the plasticization and flow of plastics, while the latter temperature mainly affects the flow and cooling of plastics. Each kind of plastic has different flow temperature. For the same kind of plastic, due to different sources or brands, its flow temperature and decomposition temperature are different, which is due to different average molecular weight and molecular weight distribution. The plasticization process of plastic in different types of injection machines is also different, so the temperature of material barrel is also different.
2. Nozzle temperature: the nozzle temperature is usually slightly lower than the top temperature of the barrel, which is to prevent the “salivation” of molten material in the straight through nozzle. The temperature of the nozzle should not be too low, otherwise the nozzle will be blocked due to the early setting of the melt, or the performance of the product will be affected due to the injection of the early setting material into the mold cavity
3. Mold temperature: mold temperature has a great impact on the internal performance and apparent quality of products. The mold temperature depends on the crystallinity of the plastic, the size and structure of the product, performance requirements, and other process conditions (melt temperature, injection speed, injection pressure, molding cycle, etc.).
