塑料吹塑是一种制造中空容器的方法。塑料吹塑的基本加工方式包括两种:注坯吹塑和挤坯吹塑。拉坯吹塑实际上是这两种基本加工方式的改进。 许多热塑性树脂可用于吹塑。最常用的有:聚乙烯(HDPE和LDPE)、聚甲酸乙二酯(PET)、聚氯乙烯(PVC)、聚丙烯(PP)、聚苯乙烯(PS)、聚丙烯晴(PAN)、聚碳酸酯(PC)。有些热塑性树脂则比较适合于上述加工方式中的某一种。目前应用最普遍的树脂是HDPE。
Plastic blow molding is a method of making hollow containers. The basic processing of plastic blow molding includes two kinds: injection blow molding and extrusion blow molding. Blow blow molding is actually an improvement of these two basic processing methods. Many thermoplastic resins are available for blow molding. The most commonly used are polyethylene (HDPE and LDPE), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polypropylene (PP), polystyrene (PS), polypropylene (PAN), poly Carbonate (PC). Some thermoplastic resins are more suitable for any of the above processing methods. The most common resin currently used is HDPE.
