Design for Economical Coring[1]

Published:

Publication history

Abstract

Cores are separate shapes, of sand, metal or plaster, that are placed in the mold to provide castings with contours, cavities, and passages. Cored holes should be designed as simply as the intended function of the casting permits. This article describes the designing of casting for the use of sand cores and to eliminate cores, with illustrations. It provides general rules for designing cored holes in investment castings. The article discusses the general principles of coremaking with illustrations. It concludes with a comparison between coring and drilling.
