What Parameters Should Be Paid Attention To In Injection Molding?

Nowadays, the application of plastic products has been 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.

1. Injection molding process product molding cycle, which includes injection molding time and product cooling time. The effective control of these times has a profound impact on the quality of the product. Before the plastic injection molding process, we should clarify the product molding cycle by the sample pattern and other methods.

2, the temperature of the injection molding mold, different plastic particles, the temperature and speed of the crystallization are not the same, and the appearance, deformation, size, plastic mold, etc. of the product have different requirements, which makes the injection mold The temperature of the mold is controlled differently when using different plastics, product requirements, etc.

3, molten plastic injection pressure, plastic in the process of filling the mold cavity is facing a lot of resistance, which makes the size of the injection pressure directly determines the size, weight, density, appearance and so on! If any of these factors are affected, then the product becomes a scrap. This requires the injection molding engineer to reasonably define the injection pressure control based on the combined factors of the product.

4, injection molding processing injection speed, the speed of injection speed has an important impact on the final appearance quality of the product. The injection speed is generally 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 the air jet method. The melt temperature plays a major role in the flow properties of the melt. The injection molding plastic has no specific melting point. It is a temperature range in a molten state. The control of both temperatures also plays a crucial role in the quality of the product.
