注塑加（jiā）工（gōng）企業技術人員指出，在（zài）注塑加工（gōng）過程（chéng）中模具的溫度是否適宜會直接影響到注塑產（chǎn）品的尺寸精度、外觀、內在質量及產（chǎn）品生產效率，由此可見模具溫度的重要（yào）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達到產品溫度的要求（qiú）。溫度（dù）調節係統根據不同的情況可（kě）以分為冷（lěng）卻（què）係（xì）統和加熱係統兩種。一般情況（kuàng）下，注塑到模具內的塑料溫度為200度左右，而（ér）注塑件成型後從模（mó）具型（xíng）腔中取出時的溫度在60度（dù）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（de）熱量快速的傳遞給模具，從而使得注（zhù）塑件冷卻後（hòu）能夠盡快的脫模。

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（yú）那些熔融塑料黏度較低、流動性（xìng）較好的塑料，如聚乙烯、尼龍和聚苯乙烯等，如果注塑件的邊壁比（bǐ）較薄，則模具可以進（jìn）行自然冷卻。如（rú）果注塑加（jiā）工模具的邊壁比較的厚，則需要人工進行冷卻，使得注塑件能盡快的定型，提高（gāo）生產效率。

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.

注塑加工時注塑模具每一階段的溫度是需要注塑人員監控（kòng）的（de），要熟練掌握加熱和冷卻係統對模具調節溫度的方法。隻有做到嚴格控製（zhì），才能使得注塑加工的過（guò）程中（zhōng）順利進行，生產出合（hé）格（gé）的產品。

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.
