Why die casting?
The potential for piece price reduction is the usual motivation for high-volume die casting. Economies of scale start at 50,000 pieces annually. Numerous factors can affect production economics. These include component complexity, alloy properties, die-casting technology used, precision of the die-cast tool, and cycle rate. One reason die casting can be thrifty is that a single cast part often replaces multiple components. And it is frequently possible to incorporate features in the casting that eliminate secondary milling, boring, reaming, and grinding operations. Flash-free die-cast tooling also eliminates the need for finishing operations. And additional savings come from material reduction, use of less-expensive metals, improved tolerances, and good part-to-part consistency. As a rule of thumb, designs incorporating complex configurations are well suited for die casting. Good candidates include gears, shafts, cams, ratchets, levers and pinions, and others performing mechanical func
