Recently there are a lot of partners injection molding conditions what, the following I will take a look at the conditions of injection molding what aspects!

1、Injection pressure

Injection pressure exists to overcome the resistance of the melt in the process of flow, or we say the other way around, the resistance that exists in the process of flow is the need for injection molding machine pressure to offset to ensure that the filling process is carried out smoothly.

2、Injection time

The injection time is very short and the impact on the molding cycle is relatively small, but the adjustment of injection time has a great effect on the gate and runner and cavity pressure control.

Reasonable injection time helps to fill the melt ideally, and it is very important to improve the surface quality of the products and reduce the dimensional tolerance.

3、Injection temperature

The injection temperature must be controlled within a certain range.

If the temperature is too low, the melt will be poorly plasticized, affecting the quality of the molded parts and increasing the difficulty of the process; if the temperature is too high, the raw material will be easily decomposed.

In the actual injection molding process, the injection temperature is often higher than the barrel temperature, the higher the value is related to the injection rate and material properties, up to 30 ℃.
