Bridging additive manufacturing and sand casting: Utilizing foundry sand

Additive Manufacturing, 2019
Abstract Although additive manufacturing technology is available for the direct fabrication of metal parts, the process is still in a juvenile state compared to older metal fabrication methods such as sand casting. Therefore, limited standards are available stipulating the use of additively-manufactured parts in critical service conditions such as ...

Helium-Assisted Sand Casting

International Journal of Metalcasting, 2012
This paper reports a novel approach to enhance the rate of heat extraction from sand castings by flowing helium gas through the sand mold during the course of the process. The effect of helium flow rate, flow direction, and mold design on the thermal profile, grain size, secondary dendrite arm spacing, and tensile properties of the castings is ...

Sand Casting Processes

2009
Sand casting is a mold based net shape manufacturing process in which metal parts are molded by pouring molten metal into a cavity. The mold cavity is created by withdrawing a pattern from sand that has been packed around it. Since the pattern imprint forms the cavity, the pattern creates the external shape of the cast part.
