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 also guarantees production efficiency.
Packaging
After all tests are completed and passed, we will package and ship the products.
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.
We will continuously track orders and follow up with customers, providing the most professional after-sales service, and constantly paying attention to customer suggestions and new needs. Customer feedback:
