Today, the application of plastic products is quite extensive, and the production process of plastic products has not been improved. It is well known that the main production method of plastic products is injection molding. The following small series will provide you with more information on injection molding.
1. Injection process product molding cycle, including injection time and product cooling time. Effective control of these times has a profound impact on the quality of the product. Before plastic injection molding, we should clarify the product forming cycle through sample patterns and other methods.
2, the temperature of the injection mold, different plastic particles, crystallization temperature and speed, different requirements, deformation, size, plastic mold, etc., which make the temperature change of injection molds When using different plastics, product requirements, etc. When the control method is different.
3, molten plastic injection pressure, plastic is facing a large resistance during filling the cavity, which makes the size of the injection pressure directly determines the size, weight, density, appearance, etc.! If any of these factors are affected, then the product will become a waste. This requires injection molding engineers to reasonably define injection pressure control based on the combined factors of the product.
4, injection molding is fast, injection molding speed has an important impact on the product's final appearance quality. The injection speed is usually achieved by adjusting the amount of oil supplied to the injection cylinder per unit time.
5. Temperature of the bucket and the temperature of the melt. The temperature of the melt can be measured at the nozzle or by air injection. The melt temperature plays a major role in the flow properties of the melt. Injection molded plastics do not have a specific melting point. It is a temperature range of the molten state. The control of the two temperatures also plays a crucial role in the quality of the product.
