Sand Casting with MetSource
Sand casting is the most widely used process to deliver cast product in a near net shape with or without internal passages. The process is versatile and cost effective even for low volume runs.

How It Works:
In the sand casting process, a pattern of the desired finished part is constructed out of hardwood, urethane, metal or foam. Sand containing bonding materials is packed around the pattern to form the mold. The pattern is removed from the bonded sand leaving a cavity in the mold that is the shape of the part. Internal passageways, including intricate structures can be added to the mold by adding cores. Molten metal is poured into the cavity and the metal solidifies. The sand is removed through a shakeout process. The gates and risers (rigging) are removed leaving the desired part for finishing.

Additional Services:
Conversion Assistance
Do you have a complicated machined hog-out or fabrication that may lend itself to converting to an investment casting? Give a MetSource engineer a call to discuss the ability to investment cast your product to improve quality, cost and/or lead-time.
Material Process Selection
Do you have a part design but want a solutions expert to advise optimal process to produce your part? Subtle changes in part design can optimize process manufacturability to reduce cost, increase part quality and / or increase throughput.


Metallurgical Assistance
Do you want to speak to a metallurgist regarding a part and environment to help with material selection? Alloy selection can greatly affect the overall cost and part manufacturability.
