摘　　要：采用气辅注射成型的方法,即在模具注射生产过程中通过气针加入氮气,氮气的作用主要是取代注塑机保压功能,对产品进行保压和补缩,同时在此过程中出现气体倒灌以及流纹,从而成功地解决了塑件可能会出现的缺陷,并开发出高质量的产品。Using gas-assisted injection molding technology, injected the nitrogen to injection mold when injecting process, the nitrogen is mainly substitutes for the injection molding machine keeping presses function, carried on to the product keeping presses and making up shrinks, simultaneously presents the gas to flow in backward as well as the class grain during this process, thus solved the production problem successfully,and develop the high grade product.
