What processes are involved in plastic injection molding?

The main precautions and processes involved in plastic injection molding:

1、 The molding cycle of injection molded products includes injection time and product cooling time, and the effective control of these times has a profound impact on the quality of the product.

Before injection molding production, we should clarify the product molding cycle through sample styles and other methods.

2、 The temperature of injection molds, the crystallization temperature and speed of different plastic particles, as well as the appearance, deformation, size, and mold requirements of products, all have different requirements;

This makes the temperature control of injection molds different when using different plastics, product requirements, etc.

3、 Molten plastic injection pressure, the plastic faces great resistance during the process of filling the mold cavity, which directly determines the size, weight, density, appearance, etc. of the product!

If any of these factors are affected, the product becomes a scrap. This requires injection engineers to reasonably define injection pressure control based on the comprehensive factors of the product.

4、 The injection speed has a significant impact on the appearance quality of the product.

The injection speed generally needs to be achieved by adjusting the amount of oil supplied to the injection cylinder per unit time.

5、 The temperature of the material barrel and the temperature of the molten material can be measured at the nozzle or using the air jet method. The temperature of the molten material plays a major role in the flow performance of the molten material;

Plastic molds do not have a specific melting point, which is a temperature range in a molten state.

The control of both temperatures plays a crucial role in the quality of the product.
