Many of the problems connected with injection molding arises because the densities of polymers change so markedly with temperature and pressure.

聚合物的密度在不同的温度和压力下变化很大，并由此产生了注射成型的许多问题。

The temperature on mold cavity's surface affects the melt's flow and cooling in the course of injection molding, then has an important part in the solution of injection molding.

在注塑加工数值模拟过程中，模腔的表面温度直接影响塑料熔体的流动和固化过程，所以模腔表面温度的计算对注塑数值模拟的结果起着极为重要的作用。

The temperature, injection speed, injectionjectio n pressure, and holding pres sure of the injection molding process should be controlled to achieve high quality of injection molded part.

温度、注射速度、注射压力和注射成型过程的保压压力是获得较高制品质量的重要影响因素。
