Metal Casting Design: Life of a Casting Reliance Foundry
Good metal casting design means creating the simplest mold that will produce a desired shape. This process requires expert knowledge of metals and casting methods to find the best value in a quality casting. End-users often need to know how a cast metal object will behave when struck, in different heat conditions—and most importantly, under load.
