Sand Casting For Manufacture - Manufacturing Process

Sand casting manufacture, however, only imparts a fair amount of dimensional accuracy to the cast part. After the sand casting is removed from the sand mold it is shaken out, all the sand is otherwise removed from the casting, and the gating system is cut off the part. The part may then undergo further manufacturing processes such as heat ...
