What processes are involved in plastic injection molding

Main precautions and processes of plastic injection molding:
1、 The injection molding cycle includes injection molding time and product cooling time. The effective control of these times has a profound impact on the quality of products.
Before injection molding production, we should define the product molding cycle through the sample style and other methods.

2、 The temperature of injection mold, the crystallization temperature and speed of different plastic particles are different, and the product appearance, deformation, size, plastic mold, etc. have different requirements;
This makes the temperature control of injection mold different when different plastics and product requirements are used.

3、 Molten plastic injection pressure, plastic is faced with great resistance in the process of filling the mold cavity, which makes the injection pressure directly determine the size, weight, density, appearance, etc. of the product!
If any of these factors are affected, the product will become a scrap. This requires injection engineers to reasonably define injection pressure control according to the comprehensive factors of the product.

4、 Injection speed, injection speed has an important impact on the appearance quality of products.
The injection speed is generally achieved by adjusting the amount of oil supplied to the injection cylinder per unit time.

5、 Barrel temperature and melt temperature. The melt temperature can be measured at the nozzle or by air jet method. The melt temperature plays a major role in the flow performance of the melt;
There is no specific melting point for plastic. The so-called melting point is a temperature range in the melting state.
The control of these two temperatures also plays a vital role in the quality of products.
