１前言滚塑成型（亦称旋转成型），是一种将聚乙烯粉料或其它热塑性树脂纵横向滚动旋转，使熔化树脂借其重力均匀地布满模具型腔的整个表面、冷却后定型制成中空制品的塑料加工工艺。目前，各国都在竞相发展滚塑工艺。欧美的一些国家，主要是美国，大约有６０多家大型的滚... 1 Introduction Rotational molding (also known as rotational molding) is a process in which a polyethylene powder or other thermoplastic resin is rolled and rotated vertically and horizontally, so that the molten resin uniformly fills the entire surface of the mold cavity by its weight, and after cooling it is shaped. Hollow products into the plastic processing technology. At present, all countries are competing to develop rotomolding technology. Some countries in Europe and the United States, mainly the United States, have about 60 large-scale rollouts...
