What parameters should be paid attention to in injection molding?
Nowadays, the application of plastic products is quite extensive, and the production process of plastic products has not been improved. As we all know, the main production method of plastic products is injection molding. The following editor will provide you with detailed information on injection molding.
1. Injection molding process product molding cycle, including injection time and product cooling time. The effective control of these times has a profound impact on the quality of the product. Before plastic injection molding, we should clarify the product molding cycle through sample patterns and other methods.
2. The temperature of the injection mold, different plastic particles, different crystallization temperatures and speeds, the appearance, deformation, size, plastic molds, etc. of the product have different requirements, which makes the temperature change of the injection mold different when using different plastics, product requirements, etc. Control method.
3. Molten plastic injection pressure, plastic faces great resistance in the process of filling the mold cavity, which makes the size of the injection pressure directly determine 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 the injection pressure control based on the combined factors of the product.
4. Injection molding processing injection speed is fast, and the injection speed has an important influence on the final appearance quality of the product. The injection speed is usually achieved by adjusting the amount of oil supplied to the injection cylinder per unit time.
5. The temperature of the barrel and the temperature of the melt. The temperature of the melt can be measured at the nozzle or by air injection method. 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 the temperature range of the molten state. The control of both temperatures also plays a vital role in the quality of the product.
