Dry flow, heating, melting wax, high temperature heating again pouring, the method for the lost wax precision casting industry is widely used, because it has the following advantages:(1) process can be automated, to save manpower, increase production rate(2) the production cost is low(3) with thin ceramic shell mold, high cooling rate after pouring castings and evenly, so its better mechanical properties.(4) better dimensional stabilityStainless steel precision casting precision casting precision casting foundry method.
face, and in the casting cooling contraction with has a tendency to leave the surface of the metal mold casting surface can be smaller slope design, and when the casting contraction tends to pressure on the metal mold casting surface should be given a larger Angle, a variety of alloy stainless steel casting foundry slope;  (3) because of the metal mold heat faster, so the stainless steel casting, the minimum wall thickness should be larger than sand mold cast castings, all kinds of casting alloy, casting the minimum wall thickness of different size; (4) stainless steel casting casting wall and the thickness of the rib in general should be connected to the outer wall thickness of 0.6-0.7, otherwise due to the cold wall (rib) slowly, when casting shrinkage crack in internal and external wall of the junction.
