Defects of transparent plastic parts formed by injection mold include silver lines, bubbles, poor surface luster, jarring lines, white fog halo and white smoke and black spots. The various defects and specific solutions are described in detail below. Of course, open plastic parts open mold injection

The injection mold is composed of two parts: moving mold and fixed mold. The moving mold is the moving part of the mold in the process of opening before the injection molding is ready to push out or take the product. The moving part is the fixed mold. Vertical injection molding machine is also known

注塑模具成型缺陷缩痕的原因及解决办法注塑模具成型缺陷缩痕主要是针对有表面外观要求的成型产品而言的，主要是指成型品表面因收缩而产生轻微凹陷的现象。注塑模具设计的时候可以考虑通过减小成形品的厚壁部分或者采用非结晶型树脂来减少缩痕缺陷的产生。注塑模具成型缺陷缩痕产生的原因主要有：1.成型条件控制不当；2.模具缺陷；3.原料不符合成型条件要求;4.塑件结构设计不合理;5.制品壁太厚或边角处热量集中，制品难以冷却。从注塑成型工艺的层面来考虑，相关的解决办法有：1. 延长保压时间；2. 提高保压压力；3. 提高注射速度；4. 降低喷嘴温度；5. 增加计量值；6. 增加缓冲量；7. 更换注射成

Injection mold two plate mold generally refers to the mold in the process of opening the mold is only divided into two halves of the moving mold side and the fixed mold side. Injection mold three plate mold is in the process of opening the mold is not separated, but the first plate and the mother te
