Many of the problems connected with injectionmolding 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, injection speed, injectionjectio n pressure, and holding pres sure of the injectionmolding 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。
