Design for Economical Sand Molding[1]

Abstract

This article begins with a schematic illustration of basic principles of sand molding. It discusses the general design factors, such as parting lines, location of radii, bosses and undercuts, and rib locations, of sand molding. The article schematically demonstrates alternative design solutions to molding and coring problems and describes the molding sequence. Draft refers to the amount of taper given to the sides of a pattern to enable it to be withdrawn easily from the mold. The article concludes with a simple example demonstrating the influence of a casting requirement on the direction of draft.
