| 脱蜡铸造法有两大类：实心模(Solid Mold)法和陶壳模(Ceramic Shell Mold)法，后者为前者的改良法。 There are two main types of dewaxing casting methods: solid Mold method and Ceramic Shell Mold method. The latter is an improved method of the former. 陶壳模法直到蜡型的制作都跟实心模法相同，只是在一次沾浆和淋砂（或浮砂）之后，并不进行包模作业，而是反复多次地进行沾浆和淋砂，直至获得预定的外壳厚度。干燥、加热、熔流出蜡质，高温加热再行浇注，这种方法为目前的脱蜡精密铸造业者所广泛采用，因其具有下列优点： The pottery shell mold method is the same as the solid mold method until the wax mold is made. Only after a dipping and sanding (or floating sand) process, the encapsulation operation is not carried out. Rather, the dipping and sanding are repeated many times until the predetermined shell thickness is obtained. Drying, heating, melting out wax, heating at high temperature and then pouring, this method is widely used by the current dewaxing precision casting industry, because it has the following advantages: (1)制程可局部自动化，以节省人力，提高生产速率 (1) the process can be locally automated to save manpower and increase production rate. (2)生产成本较低 (2) low production cost. (3)陶壳模较薄，浇注后铸件的冷却速率较高而均匀，故其机械性质较佳。 (3) Tao Kemo is thinner. After casting, the cooling rate of the casting is higher and even, so its mechanical property is better. (4)尺寸稳定性较佳 (4) better dimensional stability. 不锈钢精密铸造用精密铸型获得精密铸件的铸造方法。 Casting method of precision casting for precision casting of stainless steel for precision casting. |
