Casting Simulation (ProCAST/MAGMA) for Gating & Shell
铸造仿真软件优化浇道与壳型

ProCAST/MAGMA 对蜡模与浇道的 3D 模型做凝固与充型数值模拟，可提前预判缩孔、冷隔与卷气位置。典型流程：导入 STL → 网格划分（0.5–2 mm）→ 设定青铜浇注温度 1150℃ 与壳温 200℃ 边界 → 求解固相率场。据模拟结果把冒口移到最后凝固区，内浇口厚度上调 10–20%，一次试浇成功率可从五成提升至八成以上，省去多次实浇。
ProCAST/MAGMA runs solidification and filling simulation on the pattern-and-gating 3D model to predict shrinkage, cold shuts and gas entrapment before any pour. Typical workflow: import STL → mesh at 0.5–2 mm → set bronze pour 1150°C and shell 200°C boundaries → solve the solid-fraction field. Move risers to the last-solidifying zones and thicken gates 10–20% per results; first-pour success can rise from ~50% to over 80%, saving repeated trial castings. ---
