Improvement Measures of Ductile Iron Casting Process

1. Improvement of cavity arrangement process As shown in the figure, the improved ductile iron casting process changes the original strip arrangement into a star arrangement. The star arrangement is relatively concentrated, and heat sources are added to each other at the outer wall. The heat dissipation rate of...

Optimization of casting process and gating system

1. Optimization of gating system size Compared with the original process, in addition to the change of gate position, the biggest difference between the casting process gating system and the original process is the size of the sprue. According to the above knowledge, the design of the stepped gating...
