A Gloss defect on high-gloss injection-molded surfaces are difficult to control. This paper proposes a control methodology for a gloss defect. The maximum replication factor (RF_max) is an index representing the effect of the molding conditions on the surface gloss. As RF_max increases, the surface gloss is stabilized due to the maximized replication of the mold surface. The process window of the influencing parameters for obtaining a stable surface gloss is predicted by the range of RF_max. The predicted process window suggests specific molding conditions for controlling the gloss defect. Experiments show that the surface gloss is stabilized, and the gloss defect owing to the fluctuation of the filling conditions is suppressed in the predicted process window for poly(acrylonitrile-co-butadiene-co-styrene) and polycarbonate. The novel methodology can be applied to optimize injection-molding technologies, such as sequence valve gating and rapid heat cycle molding.

高光泽度注塑成型表面上的光泽缺陷很难控制。本文提出了一种光泽缺陷的控制方法。最大复制因子( RF _max )是表示成型条件对表面光泽的影响的指数。随着RF _{max 的}增加，由于模具表面的最大化复制，表面光泽变得稳定。获得稳定表面光泽度的影响参数的工艺窗口通过RF _max的范围来预测. 预测的工艺窗口建议了用于控制光泽缺陷的特定成型条件。实验表明，该表面光泽度是稳定的，并且由于填充条件的波动光泽缺陷在预测的过程窗口被抑制为聚（丙烯腈-共-丁二烯-共-苯乙烯）和聚碳酸酯。这种新颖的方法可用于优化注射成型技术，例如顺序阀浇注和快速热循环成型。
