山东beplay全站app安卓注塑加工技术之注塑加工中的温度控制:
Temperature control in injection molding of Shandong injection molding technology:
1.料筒温度:注射加工模塑过程需要控制的温度有料筒温度,喷嘴温度和beplay全站app安卓温度等。前两程温度主要影响塑料的塑化和流动,而后一种温度主要是影响塑料的流动和冷却。每一种塑料都具有不同的流动温度,同一种塑料,由于来源或牌号不同,其流动温度及分解温度是有差别的,这是由于平均分子量和分子量分布不同所致,塑料在不同类型的注射机内的塑化过程也是不同的,因而选择料筒温度也不相同。
1. Barrel temperature: the temperature to be controlled in the injection molding process includes barrel temperature, nozzle temperature and mold temperature. The former two temperatures mainly affect the plasticization and flow of plastics, while the latter one mainly affects the flow and cooling of plastics. Every kind of plastics has different flowing temperature. The flowing temperature and decomposition temperature of the same kind of plastics are different due to different sources or brands. This is due to different average molecular weight and molecular weight distribution. The plasticizing process of plastics in different types of injection machines is also different, so the barrel temperature is not the same.

2、喷嘴温度:喷嘴温度通常是略低于料筒高温度的,这是为了防止熔料在直通式喷嘴可能发生的“流涎现象”。喷嘴温度也不能过低,否则将会造成熔料的早凝而将喷嘴堵死,或者由于早凝料注入模腔而影响制品的性能
2. Nozzle temperature: the nozzle temperature is usually slightly lower than the high temperature of the barrel, which is to prevent the molten material from "salivating" in the straight through nozzle. The nozzle temperature should not be too low, otherwise it will cause premature solidification of molten material and block the nozzle, or the performance of the product will be affected due to the injection of premature solidification material into the mold cavity
3、beplay全站app安卓温度:beplay全站app安卓温度对制品的内在性能和表观质量影响很大。beplay全站app安卓温度的高低决定于塑料结晶性的有无、制品的尺寸与结构、性能要求,以及其它工艺条件(熔料温度、注射速度及注射压力、模塑周期等)。
3. Mold temperature: mold temperature has a great influence 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, the performance requirements, and other process conditions (melt temperature, injection speed and pressure, molding cycle, etc.).
