【摘要】 将SL原型代替蜡模用于常规的熔模铸造工艺中,在型壳的培烧过程中常出现型壳的开裂现象,本文提出从改良树脂材料、改进CAD模型的内部结构和优化制壳工艺方面进行研究,来防止型壳的开裂问题。更多还原

【Abstract】 SL pattern has been applied to conventional investment casting to replace the wax pattern though resulting in cracking on ceramic shell when being baked.Three ways to avoid cracking have been suggested that are to improve resin internal structure of CAD model and to optimize technology of shell making.更多还原
