Effective Design-

A number of factors affect the final design of a die cast component. Often, however, simple design changes can have a significant impact on the cost, speed of production and usefulness of the part. For example, casting drill spots may be preferred to casting a cored through hole. Even though an extra step is required, offhand drilling after casting may be simpler and less expensive than creating a complex die with numerous cores. 

The following illustrations provide examples of how design and engineering can affect final production.
