What parameters should be noted in injection molding?

1. The molding cycle of injection molding products, including injection molding 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 molding cycle through sample patterns and other methods.
2. The temperature of Injection mold construction, different plastic particles, crystallization temperature and speed are different, and the product appearance, deformation, size, plastic mold, etc. have different requirements, which makes the temperature change of Injection mold construction have different control methods when using different plastics, product requirements, etc.
3. Molten plastic injection pressure, plastic faces great resistance during the filling process of the mold cavity, which directly determines the size, weight, density, appearance, and so on! If any of these factors are affected, the product will become scrap. This requires injection molding engineers to define injection pressure control reasonably based on the combination factors of the product.
4. Injection molding processing has a fast injection molding speed, which has a significant impact 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 of 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 jet method. The temperature of the melt 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 crucial role in the quality of the product.
