    Sand Casting Design Rules - Pennsylvania State University

    Core design 1. An important rule in economical casting design is to eliminate as many design features requiring cores as possible. Cores that are only absolutely necessary for producing the desired shape should be used if design is to be directed toward lower cost castings. 2. Core consolidation is one such method where we reduce the total number

    Sand Casting: Introduction

    Core is a sand shape inserted into the mold to produce the internal features of the part such as holes or internal passages. Cores are placed in the cavity to form holes of the desired shapes. Core print is the region added to the pattern, core, or mold that is used to locate and support the core within the mold. A riser is an extra void created in the mold to contain excessive molten material ...
