0 Introduction
 Plastic products from product design to production, including molding plastic products design, mold design, mold manufacturing and injection molding process parameters and several other main areas. The traditional injection mold design mainly rely on the designer's experience, while the injection molding process is very complex, plastic melt flow properties of different and ever-changing products and die structure, process conditions vary, forming various defects, mold design often require repeated trial-mode, maintenance mode can be put into production, with little of a successful, identify problems, not only to re-adjust the process parameters, or even to modify the plastic products and molds, not only time-consuming and laborious, but also reduces product development time . The use of injection molding CAE technology in mold manufacturing prior to simulate injection molding process (including filling, packing and cooling) and the early detection of problems, optimize mold design and process conditions set to reduce the number of test mode in order to improve production efficiency, has become a injection molding technology is an important direction of development.

 引言
 塑料产品从产品设计到成型生产包括塑料制品设计、模具设计、模具制造和注塑工艺参数选择等几个主要方面。传统的注塑模具设计主要依靠设计人员的经验，而注塑成型过程非常复杂，塑料熔体的流动性能千差万别，制品和模具的结构千变万化，工艺条件各不相同，成型缺陷各式各样，模具设计往往需要反复的试模、修模才能投入生产，很少有一次成功的，发现问题后，不仅要重新调整工艺参数，甚至要修改塑料制品和模具，不但费时费力，而且降低了产品的开发速度。而利用注塑模CAE技术可以在模具制造前，模拟注塑过程（包括充填、保压及冷却）并及早发现问题，优化模具设计和工艺条件设定，减少试模次数以提高生产效率，现已成为注塑加工技术的一个重要发展方向。
