摘　　要：详细阐述了气体-水辅助注射成型(GWAIM)工艺的方法及过程;通过实验探讨了GWAIM工艺实施在装置设计及工艺控制中的关键技术和GWAIM工艺的优点。结果表明,GWAIM试样内壁光亮、壁厚更加均匀,具有更好的成型质量;GWAIM工艺仍然存在材料适用性问题,但相对水辅助注射成型(WAIM)工艺具有更广泛的材料适用性。In this paper,the method and process of gas-water-assisted injection molding(GWAIM)process were described in detail. The key technology of the specific device design for the GWAIM process and its process control as well as the advantages of GWAIM process were discussed based on our previous research and practical work. The results indicated that the inner wall of GWAIM was brighter,the wall thickness was more uniform,and the molding quality was better.The GWAIM process still has a problem of material applicability,but it has a wider range of material applicability than the water-assisted injection molding process.
