摘要
塑料成型产品是塑料材料的加工产品为主要结构,也称为塑料零件,塑料部件。塑料成型产品广泛应用,尤其是在电子仪器、机电设备、通信工具、生活用品、等,获得大量的应用。各种受力不大的壳体、结构、装饰、等;用于各种塑料异型材、板和门窗,塑料中空容器与塑料制品和各种各样的生活用塑料制品等。
塑料零件以塑料成型加工为主要加工方法。塑料成型各种塑料原材料(粉、粒状、熔化或分散)塑化的要求或加热熔融塑料的状态,在一定的压力下,要求形状模具或填充到模具型腔形状,等待冷却定型后,获得所需的形状和大小几个塑料零件生产过程。其特点是生产的产品形状尺寸很稳定,可实现连续生产,一模多件,生产效率高。
常用的塑料注射成型工艺有注塑成型、压缩成型,吹塑等,注塑是一种主要塑料模塑成型方法。注塑技术出现了许多新工艺方法,如热固性塑料注射成型、排气注射成型、反应注射成型以及各种塑料注塑。

Abstract:(Times New Roman)
Plastic molding products are widely used, especially in electronics, electrical equipment, communication tools, daily necessities, such as a large number of applications. Such as the big shell, frame, base, structural parts, decorative parts; All kinds of plastic pipe used in construction, metal plate and profile doors and Windows; Hollow plastic containers and plastic products, such as life.
The Main processing plastic processing methods of plastic parts. Plastic molding is the various types of plastic raw materials (powder, granular, melting or spread) of plastics melt or heat conform to the requirements of the country, under a certain pressure after shape mould requirement or request mold - filled cavity, stereotype is the shape, size, quantity after cooling requirements of plastic parts production process properties. Stability in the shape of production on the size of products, can realize continuous production, more than one mode of production, high productivity
Common plastic molding process is injection molding, compression molding, blow molding, injection molding is a main forming method. Injection molding technology has a lot of new technical methods, such as material non - condensate injection flow, thermosetting plastic injection molding, exhaust injection molding, reaction injection molding, and the total number of all kinds of plastic injection molding
