注塑加工廠根據用戶的（de）需求，將熱（rè）融化的材料由高（gāo）壓射入模腔，經冷（lěng） 卻固化後得到某些形狀複雜的部件，注塑加工是（shì）經（jīng）常（cháng）用到的部件加工方法。下麵，注（zhù）塑加工廠為您介紹（shào）一下注（zhù）塑加（jiā）工過程中的溫度控製：
According to the needs of users, the injection molding plant injects the hot melt materials into the mold cavity from high pressure, and obtains some complex parts after cooling and curing. Injection molding is a frequently used part processing method. Next, the injection molding factory will introduce the temperature control during injection molding:
1、料筒（tǒng）溫度：注射模塑過程需要控製的溫度有（yǒu）料筒溫度，噴嘴溫度和模（mó）具溫（wēn）度（dù）等（děng）。前兩種（zhǒng）溫度主要影響塑料的塑（sù）化和流動，而後一種（zhǒng）溫度主要是影響塑料的流（liú）動和冷（lěng） 卻。每一種塑料都具有不同的流動溫度，同一種塑料，由於來源或牌號（hào）不同，其（qí）流動溫度及分 解溫度是有差別的，這是由於（yú）平均分子量和分子量分布不同所致，塑料在不同類型的注（zhù）射機內的（de）塑化過程也（yě）是不同的，因而選擇料筒溫度也不相同（tóng）。
1. Barrel temperature: the temperature to be controlled in the injection molding process includes barrel temperature, nozzle temperature and mold temperature. The first two temperatures mainly affect the plasticization and flow of plastics, and the second temperature mainly affects the flow and cooling of plastics. Each plastic has different flow temperature. For the same plastic, due to different sources or brands, its flow temperature and decomposition temperature are different, which is due to different average molecular weight and molecular weight distribution. The plasticization process of plastics in different types of injection machines is also different, so the barrel temperature is also different.

2、噴嘴溫（wēn）度：噴嘴（zuǐ）溫度通常是略低於料筒高溫度的，這是為（wéi）了防止熔料在直通式噴嘴可能發生（shēng）的"流涎現象".噴嘴溫度也不（bú）能過低，否則將會造成熔料的（de）早凝而將噴嘴（zuǐ）堵塞，或者（zhě）由於早凝料注入模腔而影響製（zhì）品的性能。
2. Nozzle temperature: the nozzle temperature is usually slightly lower than the high temperature of the barrel, which is to prevent the "salivation" of molten material in the straight through nozzle. The nozzle temperature should not be too low, otherwise it will cause the early setting of molten material and block the nozzle, or affect the performance of the product due to the injection of early setting material into the mold cavity.
3、模具溫度：模具溫度對製品的內在性能（néng）和表觀質量影響很大。模具溫度的高低（dī）決定於塑料結晶性的（de）有無、製品的尺（chǐ）寸與結構、性能要求，以及其它工藝條件（熔料溫度、注射速度及注射壓力、模塑周期等）。
3. Mold temperature: mold temperature has a great impact on the internal performance and apparent quality of products. The mold temperature depends on the crystallinity of the plastic, the size and structure of the product, performance requirements, and other process conditions (melt temperature, injection speed, injection pressure, molding cycle, etc.).
