Because the stainless steel plate precision casting in the metal type in the cooling condensation faster than in the sand mold, the metal type does not have allowability, wax casting and therefore in the metal type forging, its casting in the formation of forging stress than sand mold castings to be large crack selectivity is also large, in the adoption of the link is also very easy to cause insufficient pouring and its cold compartment condition. Stainless steel plate precision castings of uniform thickness, its wall between too much and the joint of the place to alleviate, goods more corner at the arc moderate and other areas of the standard to be more stringent than the sand mold casting castings, machinery and equipment should be vertical connection of the wall into a skewed connection.
Stainless steel castings for the construction of a more lacking part of the need to set up a rib, convex mold, etc. to give a boost, so that it can reasonably control its forging cracks, in the adoption of the link, should try to avoid having to block the casting arbitrary expansion of the convex mold, rib, convex platform and other projection part. Stainless steel castings must be reasonably laid out to enhance its rib when adopted in the link must also give full consideration to the hazards it poses to the casting closing, that can also avoid the metal type forging castings caused by insufficient pouring, and its cold compartment and other levels should be concerned about the structural difficulties.
Stainless steel castings wall thickness to moderate power energy too thin, especially when the casting wheelhouse size is too large process can not be too thin, the goods to be reasonable. Precision casting manufacturers in the adoption of the link must avoid the large plane, because it is the casting in the case of pouring, the metal liquid rises more slowly. Cast iron parts gas understanding of the surface is large, easy air oxidation, at the same time because of its metal exhaust heat fast, its metal liquid will then quickly lose its circulation, it is easy to lead to its pouring is not enough, welding tumor, cold compartment and other shortcomings.
