FOUNDRY
CAPABILITIES
Chicago Aluminum Castings Co. provides engineering assistance to help
design cost effective cast aluminum parts, or to help turn fabricated parts into castings of greater
economy, productivity and end-result efficiency. We assist with pattern design to customer requirements to
insure accuracy and proper gating/risering techniques. High engineering standards coupled with scrupulous
quality control procedures insure that the quality of our castings meets all technical
requirements.
