摘　　要：通过总结近年来注塑成型熔接痕的研究现状,阐述熔接痕的形成机理,综述较经典的熔接痕强度预测模型及熔接痕自动识别算法等熔接痕强度预测研究,并从微观角度归纳了对熔接痕的研究,指出成型工艺中熔体温度、模具温度及注射压力是影响熔接痕的主要因素。在传统注塑成型基础上,介绍了快速变模温注塑成型等注塑成型新技术和改进模具结构2种改善熔接痕的新方法。The research status of weld line in injection molding was introduced.The formation mechanism of weld line was expounded.The strength prediction studies of weld line such as prediction model and automatic recognition algorithm were summarized.The studies of the weld-line in microcosmic view were concluded,and the influences of the melt temperature,mold temperature and injection pressure on the weld-line were achieved.Based on the traditional technology of the injection molding,rapid heat cycle molding which was a new injection molding technology to improve weld line was presented,and two new kinds of optimizing mold structure were introduced as an improvement of weld line.
