生产过程中，模具温度是影响部件质量高低的一个重要因素。一般而言，设置较高的模温通常可获得较高的部件表面质量。冷/热循环模具注塑技术是在注塑循环过程中，利用热循环控制模具温度的一种方法。该技术要求模具表面的加热温度要在塑料的玻璃化转变温度(Tg)之上，以利于注塑，然后快速冷却模温，使部件冷固，以便于顶出。
In the production process, the die temperature is an important factor affecting the quality of parts. Generally speaking, setting a higher die temperature usually results in higher surface quality of shuzhi.07858.netchejiareqi.07858.netruhuaji.07858.netwenbanji.07858.netcomponents. The injection juyixiban.07858.netguangyou.07858.nettechnology of cold/hot cycle mould is a method to control the temperature of mould by using thermal cycle in the process of injection cycle. The technology requires that the heating temperature of the die surface should be above the glass transition temperature (Tg) of the plastic for injection, and then the die temperature should be rapidly cooled to make the parts cold and easy to eject.
