| 熔模铸造制造 Investment casting manufacturing 熔模铸造生产的第一个工序就是制造熔模，熔模是用来形成耐火型壳中型腔的模型，所以要获得尺寸精度和表面光洁度高的铸件，首先熔模本身就应该具有高的尺寸精度和表面光洁度。此外熔模本身的性能还应尽可能使随后的制型壳等工序简单易行。为得到上述高质量要求的熔模，除了应有好的压型（压制熔模的模具）外，还必须选择合适的制模材料（简称模料）和合理的制模工艺。 The first process of investment casting is to make investment mold, which is used to form the model of medium-sized cavity of refractory shell. Therefore, in order to obtain castings with high dimensional accuracy and surface finish, the investment mold itself should have high dimensional accuracy and surface finish. In addition, the performance of the investment mold itself should make the subsequent process of shell making as simple as possible. In order to get the high quality investment mold, we must choose the suitable mold material and reasonable molding technology besides the good molding. |
