注塑加工企业技术人员指出，在注塑加工过程中模具的温度是否适宜会直接影响到注塑产品的尺寸精度、外观、内在质量及产品生产效率，由此可见模具温度的重要性。

The technicians of injection molding enterprises pointed out that whether the mold temperature is appropriate in the injection molding process will directly affect the dimensional accuracy, appearance, internal quality and product production efficiency of injection molding products, which shows the importance of mold temperature.

注塑加工需要温度调节系统来达到产品温度的要求。温度调节系统根据不同的情况可以分为冷却系统和加热系统两种。一般情况下，注塑到模具内的塑料温度为200度左右，而注塑件成型后从模具型腔中取出时的温度在60度以下。

Injection molding requires temperature regulation system to meet the requirements of product temperature. Temperature regulation system can be divided into cooling system and heating system according to different conditions. In general, the temperature of the plastic injected into the mold is about 200 degrees, while the temperature when the injection molded part is taken out of the mold cavity is less than 60 degrees.

热塑性塑料在注塑成型后，必须对模具进行有效的冷却，使得塑料的热量快速的传递给模具，从而使得注塑件冷却后能够尽快的脱模。

After the injection molding of thermoplastic, the mold must be cooled effectively to make the plastic heat transfer to the mold quickly, so that the injection molded parts can be demoulded as soon as possible after cooling.

对于那些熔融塑料黏度较低、流动性较好的塑料，如聚乙烯、尼龙和聚苯乙烯等，如果注塑件的边壁比较薄，则模具可以进行自然冷却。如果注塑加工模具的边壁比较的厚，则需要人工进行冷却，使得注塑件能尽快的定型，提高生产效率。

For those plastics with low viscosity and good fluidity, such as polyethylene, nylon and polystyrene, if the side wall of the injection molded part is relatively thin, the mold can be cooled naturally. If the side wall of the injection mold is relatively thick, it needs to be cooled manually, so that the injection parts can be shaped as soon as possible and improve the production efficiency.

注塑加工时注塑模具每一阶段的温度是需要注塑人员监控的，要熟练掌握加热和冷却系统对模具调节温度的方法。只有做到严格控制，才能使得注塑加工的过程中顺利进行，生产出合格的产品。

During injection molding, the temperature of each stage of the injection mold needs to be monitored by the injection molding personnel. It is necessary to master the method of adjusting the temperature of the mold by the heating and cooling system. Only by strict control can the injection molding process be carried out smoothly and produce qualified products.
