In this thesis, firstly the contents of IMA have been introduced and reviewed, and it is concluded that IMA is one kind of multi-shot molding technology.
本文首先对模内装配技术的内容进行了介绍和定义，明确了模内装配技术也是多重注塑技术的一种。
Using one new advanced multi-shot molding technology called"in-mold assembly (IMA)", IMA products have better quality than the standard injection molding parts does.
作为新型的多重注塑的一种，模内装配技术具有产品质量好、生产效率高和大批量生产单件成本低等优点。
The cause of usual molding fault in the course of injection forming, such as the short shot, the viscous flow and the sedimentation tache, was analyzed.
对注射成型过程中常见的成型缺陷(如短射、滞流和沉降斑)的形成原因进行了分析。
In this case, the course of the technique implement is stated, analyzed the connection between over molding and twin-shot injection mold and the features belong to each other.
叙述了实际塑件的工艺改善过程，分析了包胶模工艺与双色模工艺的联系及各自的特点。
Step3 inject remain 1/3 of product. According to product molding speed and pressure lower than that of step2 To prevent flash speed and pressure should decrease but it can't shot short.
第三段是注射余下的 1/3 段，其速度和压力根据产品的需要，一般是小于第二段，速度和压力存在于一 个往下降的过程。主要是为了防止产品毛边的产生，但同时又必须把产品充填饱满。
Step3 inject remain 1/3 of product. According to product molding speed and pressure lower than that of step2 To prevent flash speed and pressure should decrease but it can't shot short.
