However, our custom aluminum castings routinely offer that very possibility. We provide engineering assistance to help design cost effective cast aluminum parts, or to help turn fabricated parts into castings of greater economy and productivity. We assist with pattern design to customer requirements. High engineering standards coupled with scrupulous quality control procedures insure that the quality of our castings meet all technical requirements. A titanium-boron grain refiner is added to insure high quality, and magnesium is added to maintain correct alloy chemistry.
Molten aluminum is vacuum tested before pouring to prevent gas inclusions in the final castings.
During pouring, all metal is filtered through fiberglass or mica screens to exclude impurities. We conduct final clean-up operations on all castings to include removal of parting lines, excessive roughness, burrs, etc. to insure that the castings you receive from Chicago Aluminum Castings Co., Inc. meet your individual applications.
