The manufacturing of multi-stage pump bodies through casting is a systematic project that integrates materials science, mold engineering, thermal processing techniques, and quality inspection. The precision control of each link directly affects the operational performance and safety reliability of the pump set. With the continuous increase in the demand for multi-stage pumps with "high head, high efficiency, and long service life" in the industrial field, casting technology also needs to develop towards greater accuracy, higher efficiency, and more environmental friendliness - for instance, by optimizing the melting and casting parameters through numerical simulation technology to reduce trial-and-error costs; using 3D printing technology to manufacture complex sand cores to enhance the accuracy of the flow channels; and promoting low-energy consumption heat treatment processes to reduce energy consumption during the production process. Only by continuously promoting technological innovation and process upgrading can the quality level of cast multi-stage pump bodies be continuously improved, providing a solid guarantee for the stable operation in the field of fluid transportation.

In sand casting, shrinkage cavities and shrinkage porosity are the most common internal defects in castings. Shrinkage cavities typically manifest as irregular large cavities in thick areas or heat center zones of the casting, characterized by rough walls and dendritic crystals. Shrinkage porosity appears as fine dispersed pore clusters, predominantly occurring along casting axes or at thickness junctions. These defects severely compromise mechanical properties and airtightness, potentially leading to cracks and premature failure. As core processes in the casting workflow, mold design and core-making operations play a decisive role in preventing shrinkage porosity and cavities. This article systematically outlines effective measures to reduce their occurrence rates by focusing on critical aspects of mold-making procedures.
