molding cycle meaning in English

模塑周期

Abstract : thermally induced stress and the relevant warpage cause by inappropriate mold design and processing conditions are problems that confounded the overall success of injection molding . a thermorheologically simple thermoviscoelastic two - dimension material model is used to simulate the residual stress and warpage within injection molded parts generated during the cooling stage of the injection molding cycle . the initial temperature field corresponds to the end of the filling stage . the fully time - dependent algorithm is based on the calculation of the elastic response at every time step . numerical results are discussed with respect to temperature and pressure
文摘:不均匀的热残余应力及其变形是注塑成型加工中常见的工程问题之一.应用热流变简单材料的二维热粘弹本构方程得到的递推公式，数值模拟了成型中的热残余应力及其翘曲变形，并用数值实验讨论了温度、压力对注塑件残余应力及变形的影响，发现温度变化不均匀是注塑件翘曲变形的最主要原因，其影响远大于压力的作用，与工程实验的结论一致
