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。

Abstract:
Plastic molding plastic products is the main structural material obtained by forming products, also known as plastic parts, plastic parts for short. Plastic molding products are widely used, especially in the electronic instruments, electrical equipment, communication tools, daily necessities, such as a large number of applications received. such as a large shell, frame, base, structural parts, decorative parts; all kinds of plastic pipe used in construction, sheet metal and profile windows and doors; hollow plastic containers and plastic products such as life.
The main processing of plastic parts are made of plastic processing method. Plastic molding is to various types of plastic raw materials (powder, granular, melt or dispersion) plastics melt or heating plastic to meet the requirements of state, to a certain shape under pressure after a request to the requirements of mold or mold-filled cavity, stereotypes to be cooling after it has been requested the shape, size, number of properties of plastic parts of the production process. Characterized by the shape of the production of dimensionally stable products, can realize continuous production, more than one mode of production, high productivity
Common type of plastic molding processes are injection molding, compression molding, Blow Molding and so on, plastic injection molding is a molding method of forming a major. Injection molding technology there are many new technical methods, such as material non-condensate flow injection molding, thermoset plastic injection molding, the exhaust injection molding, reaction injection molding, as well as the total number of varieties of plastic injection molding
