The aerospace industry has used magnesium sand cast
components for decades; the process knows almost no limitations on component size or geometry, and the limited production capabilities make it ideal for high-integrity castings requiring special processing.
FEF provides the cast
metals industry with an adequate supply of college-degreed, technical manpower; develops a favorable climate for casting research by directing the interest of a larger number of professors and students to the casting field; and promotes knowledgeable teaching staffs and practical cast
metals courses at colleges and technical institutes.
Casting the hull section would reduce the lead time by half and eliminate most of the machining, but the question remained as to whether the section would find success as a converted cast
With proper casting design parameters, gating and risering techniques, and overall solidification characteristics, a porosity-free and inclusion-free cast
product can result when molten metal quality is carefully controlled.
The metalcasting industry recognized seven cast
components as top designs for the 2006 Engineered Casting Solutions and American Foundry Society Casting Competition.
