Stainless steel clad sand casting

After selecting the molding method, the location of the pouring for the laminated sand mold is generally determined. First determine the parts of the casting (such as critical processing surface, force parts, bearing parts, etc.) with strong quality requirements. Estimate the key waste trends and parts prone to defects (such as thick parts prone to shrinkage defects. Weld crust is easy to produce on the large plane. Pouring less than the ball laminated sand casting side plate thin wall parts, cold compartment is easy to occur. Part stress thickness difference is too large, easy to appear cracks, etc. In determining the location of the clad sand casting furnace bar pouring, should make the key parts in a beneficial state, and take appropriate process measures to avoid easy to appear defects.

The material is made into the structural shape of the part, and then the mold is placed into the sand mold. As a result, an inner cavity with the same structural dimensions as the part is formed in the sand mold, and then the flow liquid is poured into the inner cavity. After the liquid condenses, a part with the same shape and structure as the mold can be produced. It can also be used in casting machines and can be used in random mold machines.

1 When using elastic parts such as torsion springs, the torsion springs are easily damaged and generally break and deform. The method is to replace. Replacement should pay attention to the specifications and models of torsion springs. The specification and type of torsion spring should be determined by color, tube diameter and length. It should be replaced only when the three items are the same.
