Application of precision casting technology for Baozhu sand shell mold？

The precision casting process of Baozhu sand shell has developed rapidly in recent years, from the initial bucket teeth of construction machinery to general parts such as valves, water heaters, automotive parts, tool hardware parts, from cast iron, cast carbon steel, to stainless steel, heat-resistant steel, and non-ferrous alloys, extending to various fields such as sand casting, metal casting, and precision casting, achieving good economic and social benefits.

From the perspective of casting technology, the precision casting process of Baozhu sand shell has been widely applied in the following three fields:

a. Partially replace the lost wax precision casting process. Especially for castings with relatively simple shapes and some castings that require cores;

b. In situations where quartz sand shell casting was originally used, the precision casting process of bead sand shell casting is adopted to improve process adaptability;

c. Small cast steel parts originally produced using ordinary sand casting technology have been replaced with new precision casting processes such as bead sand shell casting to improve casting quality, reduce sand consumption, and increase casting production efficiency.
