Cost-Effective Casting Design: What Every Component Designer Should Know

摘要

Viewing these six key factors as a system-while sketching geometries-provides a workable methodology for consistently good casting designs. Structural design engineers who work successfully with castings commonly design in a narrow group of casting types poured from familiar alloys (like the family of irons or the 300 series of aluminum) and molded from familiar foundry processes (like green sand or nobake). Rules of thumb have been developed over the years for common design situations. Close inspection of these rules reveals that they sometimes recommend conflicting geometry. For example, the use of gusseting instead of mass for stiffness might be labeled "recommended" in one set of design rules and "poor" in another.
