Sand Casting of Metals. Elizabeth Merten University of Washington, Seattle Department of Materials Science & Engineering [email protected] Key Concepts in Sand Casting. Simple and Inexpensive Utilized to make simple shaped parts Can alter Mechanical Properties of Materials
*Zinc and some metal oxides can be hazardous. This is due to the metal fumes created in the sand casting process.

The wetness of the sand mixture is very important in Sand Casting. If the sand is too wet the mold can explode and if it is too dry it can collapse
Testing your green sand mixture:
After casting the part be sure to note any imperfections on the surface
If equipment is available, section the part and note any inclusions
*Remember to wear proper safety equipment
( leather apron, gloves, and Face Shield)
Simple Shapes for ornamental items as well as parts for the Automotive, Aerospace industry can be cast from Iron, Bronze and Aluminum

Flaws on the surface can easily be identified however internal flaws are more difficult to discover and can significantly effect the quality of the cast piece
