PVC真空吸塑装饰片膜压工艺控制要点

发布人:临沂盛邦pvc装饰材料公司   文章链接:http://jwkkm.com/news/203.html

  PVC真空吸塑装饰片膜压工艺控制要点:PVC膜压技术在家具行业尤其是门板和橱柜生产中非常重要。中高密度基材加工成各种线型再吸塑上各种亚光高光、花色、质感的PVC膜,使产品丰富多彩,琳琅满目,给消费者创造了很大的选择空间。然而,应用这项技术制造的产品。其品质的优劣却千差万别。造成这些差别的原因除了基材和饰面材料PVC吸塑膜本身因素外,加工过程中的工艺参数的控制也至关重要。下面以进口的某型号正负压真空吸塑机为例,运用德国进口的双组份吸塑胶,对整个工艺过程进行说明。
