摘　　要：对气辅注射成型一维充填过程的初始注射量进行了研究,并推导出了熔体最小注射量的计算公式。为气辅注射成型工艺的实际应用起到了指导作用。Long, cylindrical parts are usually produced with Gas-Assisted Injection Molding （GAIM） which can greatly reduce the required injection pressure and the parts＇weight. However, improper setting of initial injection melt will lead to insufficiency of gas penetration or gas blow out. therefore analysis of the initial injection melt is necessary. In this article ,the initial injection melt in the gas-assisted injection process was studied as gas penetration taking place in 1-dimension model, the volume of gas hollowing out was equal to the same of the melt front advancing during the filling stage of the whole process ,also the formula for the minimum injection melt was given finally which can give directions for practice.
