In order to evaluate the rationality of the optimized process scheme, the software ProCAST needs to be used to simulate and calculate the optimized sand mold casting process scheme of mud pump body again. After the finite element division of each part is completed, the parameters need to be...
Traditional sand casting mostly constructs the mold cavity and core seat through wood mold or metal pattern. It has an important impact on the geometry, dimensional accuracy and surface roughness of the casting, and is directly linked to the production efficiency and cost of the casting. The pattern and...
