1、本科机械毕业设计论文CAD图纸QQ401339828摘要塑料成型制品是以塑料为主要结构材料经成型加工获得的制品，又称塑料制件，简称塑件。塑料成型制品应用广泛，特别是在电子仪表、电器设备、通信工具、生活用品等方面获得大量应用。如各种受力不大的壳体、支架、机座、结构件、装饰件等；建筑用各种塑料管材、板材和门窗异型材；塑料中空容器和各种生活用塑料制品等。塑料制件的主要加工方法是塑料成型加工。塑料成型是将各种形态的塑料原料（粉状、粒状、熔体或分散体）熔融塑化或加热达到要求的塑性状态，在一定压力下经过要求形状模具或填充到要求模具模腔内，待冷却定型后，获得要求形状、尺寸几性能塑料制件的生
2、产过程。其特点是生产制品形状尺寸稳定，可实现连续生产，一模多件生产，生产效率高。常用的塑料成型工艺有注射成型、压缩成型、中空成型等，注射成型是塑料模塑成型的一种主要成型方法。注射成型技术出现了许多新的工艺方法，如无流道凝料注射成型、热固性塑料注射成型、排气注射成型、反应注射成型以及多品种塑料的共注射成型。关键词:塑料制件；注塑成型；19本科机械毕业设计论文CAD图纸QQ401339828AbstractPlasticmoldingplasticproductsisthemainstructuralmaterialobtainedbyformingproducts,alsokn
