Manufacturing Process:

This part is manufactured using the resin-coated sand shell gravity casting process, which improves surface roughness, ensures stable casting dimensions, significantly enhances the mechanical properties of the part, and maintains high production efficiency. For such large-sized parts, internal cooling and molten metal flow design are crucial. Uneven internal cooling can easily lead to localized structural collapse and internal shrinkage porosity. Through continuous debugging and testing of the mold, we have obtained parts with a dense structure and perfect quality.

After casting, the parts undergo annealing heat treatment to relieve internal stress and improve subsequent machining performance. Upon completion of all casting and machining processes, we perform coordinate measuring machine (CMM) inspection to ensure all dimensions meet specifications.

Packaging

After all tests are completed and passed, we will package and ship the products.
