摘　　要：针对水辅助注射制品的质量,从宏观现象(如高压水的第一次穿透过程不稳定性、模具型腔变截面处的熔体堆积现象、制品成型过程中的指状效应)和微观现象(沿制品厚度方向的纤维取向及分布、不同区域的晶体类型及结构)以及其相对应的相关工艺优化进行了综述。Aimed to the quality of waterassisted injection molded parts,this paper presented a survey for their defects and relevant process optimization from the macroscopic phenomena such as the first penetration process of highpressure water instability,the phenomenon of melt accumulation at the mold cavity variable cross section,the formation of water fingerings during the process and the microscopic phenomena like fiber orientation and distribution along the thickness of the parts,and crystal types and structures in different regions.
