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 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 the injection mold, different plastic particles, different crystallization temperature and speed, product appearance, deformation, size, plastic mold, etc. have different requirements, which makes the temperature of the injection mold change when using different plastics, product requirements, etc. , the control methods are different. 3. Molten plastic injection pressure, the plastic faces great resistance in the process of filling the cavity, which makes the injection pressure directly determine the size, weight, density, appearance and so on! If any of these factors are affected, the product becomes scrap. This requires injection molding engineers to reasonably define injection pressure control based on product combination factors.

4. Injection molding processing The injection molding speed is fast, and the injection molding speed has an important impact on the final appearance quality of the product. 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 injection. 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.
