一、模具对热塑性塑料而言,可通过对注射成形预制件固化阶段的变形,使制件的内部强良增加。采用注射压缩工艺,对制件内部分子结构排列方向进行校准,这样可获得高强度制件或使制件局部区域强度增加。为此就需要有预制件成形模具和附加模具,在附加模具中使预制件压缩成增强型制件。这种加工工艺和其他工艺的区别,一方面是在于它能使制件的内部强度增加,另一方面也正是由于这种方法能使制件内部增强而产生了新工艺。
First, the mold for thermoplastics, through the deformation of the injection molding pre-curing stage, so that parts of the internal strength and increase. The use of injection compression process, the alignment of the molecular structure within the workpiece alignment direction, so you can get high-strength parts or parts of the local area strength increases. For this purpose, a preform forming mold and an additional mold are required to compress the preform into a reinforced part in an additional mold. The difference between this process and other processes is that on the one hand it increases the internal strength of the part and on the other hand it is due to the new process that results from the internal reinforcement of the part.
