用作汽车内面板如门装饰和仪表板的表面护板一般是用薄壳模塑的PVC来制造。薄壳模塑工艺本身并不理想,因为速度慢,能量密集,且过长的温度循环时间能导致镍模具的完全损坏。操作该种加工工艺的最有效方法是使表面护板在热时脱模,由于它们易被损坏,所以不能利用机器人把其从模具? Surface guards used as automotive interior panels such as door trim and dashboards are generally made of thin-walled, molded PVC. The shell molding process itself is not ideal because of slow, energy-intensive, and long temperature cycling times can lead to complete damage to the nickel mold. The most effective way to handle this type of processing is to release the surface protection panels when they are hot and they can not be removed from the mold by the robot because they are easily damaged.
