In injection molding, any variation in processing that keeps the molding resin hot throughout filling allows increased relaxation and, therefore, decreased orientation.

在注塑成型时，整个填料过程始终保持成型树脂高温的任何加工变化都会增加松弛作用而减少方向性。

For PET resin, the processing temperature window of which is relatively narrow, hot runner plate could be used in the multi-cavity hot runner injection molding.

对于注射成型加工温度范围较窄的PET塑料，可利用热流道板实现一模多腔热流道注射成型。

Its processing easy and hot and high performance makes it particularly suitable for the injection molding process to optimize productivity.

其加工简易和热性能高的特点使其特别适宜于在注塑模塑加工中优化生产率。
