Abstract: In its simplest form, casting involves using a pattern to form a mold cavity into which molten metal is poured and solidified. Gray iron is one of the most versatile metals, but knowledge of its distinct characteristic is integral to an efficient design. This article details 10 rules of gray iron design. Rules such as (1) design for soundness, (2) avoid sharp angles and corners, (3) employ uniform sections while minimizing the number of sections, (4) avoid abrupt section changes and (5) avoid using bosses, lugs and pads. A number of correct vs. incorrect design sketches are included in the article.
