摘　　要：分析了熔接痕的形成原因,指出了制品结构、模具设计制造和成型工艺对熔接痕的影响,最后从制品、模具、工艺等多方面系统地提出了调整熔接痕位置、控制熔接痕强度的措施,并针对大型注射件提出了多浇口进料顺序控制技术的原理和应用。The cause of the forming of fusion seam was analyzed, and the influence of product structure, mould design and manufacture and forming technology on fusion seam was presented. Then the measures from aspects of design of products, moulds and techniques to adjust the position and to control the intensity of fusion seam were proposed. The principle and application of the control technique of multi-sprue feeding sequence for large injection parts were discussed as well.
