4 q5 H: p8 G# i# t& j流道设计与进浇口位置除了关系到充填时间的长短，更直接影响充填是否平衡。充填如果时间过长， 会导致产品生产速度过慢，造成成本提高；而充填不平均，会使往后保压、冷却阶段无法发挥其功效，造 成收缩不均与应力集中等问题发生，导致产品质量不佳。本研究利用 Moldex3D 模流分析软件仿真后，得知 流道的设计以直线型的流道较为优异，充填时间较 S 型流道节省约 20%。而采用较佳的进浇口设计可使得 翘曲变形量约减 40%。

% i: F  N+ l  ~* [7 r3 D1 lBesides filling duration, runner design and gate location matter a lot to flow balance as well. Longer filling time will lengthen production cycle time and further increase the cost; unbalanced flow will decrease the effect of packing and cooling, cause uneven shrinkage and stress concentration, and result in bad product quality. In this study, a CAE simulation tool, Moldex3D, is applied to investigate if the runner design and gate location are appropriate to the product. Through the simulation result, it shows the material in a linear runner will be saved by
20% than the original S-shaped one; moreover, an optimized gate location will contribute 40% reduction of warpage.
