What process does plastic injection processing include？

The main points for attention in plastic injection molding and the process involved are as follows:
1、 Injection 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 products.
Before injection molding production, we should make clear the product molding cycle through the sample style and other methods.
2、 Injection mold temperature, different plastic particles, the crystallization temperature, speed are not the same, as well as the product appearance, deformation, size, plastic mold and so on have different requirements;
This makes the temperature of the injection mold in the use of different plastics, product requirements and other circumstances, the mold temperature control is not the same.
3、 Molten plastic injection pressure, plastic in the process of filling the mold cavity is facing great resistance, which makes the size of the injection pressure directly determines the size, weight, density, appearance of the product!
If any of these factors are affected, the product will become a scrap. This requires injection engineers to reasonably define the injection pressure control according to the comprehensive factors of the product.
4、 Injection speed, the speed of injection has an important impact on the appearance quality of products.
Injection speed is usually achieved by adjusting the amount of oil supplied to the injection cylinder per unit time.
5、 The melt temperature can be measured at the nozzle or by air jet method, and the melt temperature plays an important role in the flow performance of the melt;
Plastic has no specific melting point, the so-called melting point is a melting state of the temperature range.
The control of the two temperatures also plays an important role in the quality of products.
