注塑加工企業技術人員指出，在注塑加工過程中（zhōng）模具的溫度是否適宜會（huì）直接影響到注塑產（chǎn）品的尺寸精度、外觀、內在質量及產品生產效率，由此（cǐ）可見（jiàn）模具溫度（dù）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.

注塑加工需要溫度調節係統來（lái）達到產品溫度的要求。溫度（dù）調節係（xì）統根據不同（tóng）的（de）情況可以分為冷卻係統和加熱係統兩種。一般情（qíng）況下，注塑到模具內（nèi）的塑料溫度為200度左右，而注塑件成型後從模具型腔中取出時的溫度在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.

熱塑性塑料在注塑成型後，必須對模具進行有效的冷卻，使得塑料的熱量快速的傳遞給模具，從而使得注塑件冷卻後能夠盡（jìn）快的脫模。

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.

對於那些熔融塑料黏度較（jiào）低、流動性較好的塑料，如聚乙烯（xī）、尼龍（lóng）和聚苯乙烯等，如果注塑件（jiàn）的邊壁比（bǐ）較薄，則（zé）模具可以進行自然冷（lěng）卻（què）。如果注塑加工模具的邊壁（bì）比較的厚，則需要人工進行冷卻，使（shǐ）得注（zhù）塑件能盡快的定型，提高生產（chǎn）效率（lǜ）。

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.

注塑加工時注（zhù）塑模（mó）具每一（yī）階段的溫度（dù）是需（xū）要注塑（sù）人員監控的，要熟練掌握加（jiā）熱和冷卻係統對模（mó）具調節溫度的方法。隻有做到嚴格控製，才能使（shǐ）得注塑加工的過程中順利進行，生產出合格的產品（pǐn）。

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.
