Best-In-Class
Electronics Mount Aristo-Cast Inc.
Almont, Michigan
Material: AZ91E-T6 magnesium. Process: Investment casting. Weight: 54 grams. Dimensions: 3.681 x 4.488 x 2.953 in. Application: Hand-held device used in aerospace.
• T e component acts as a bracket to mount processing elec- tronics and acts as a heat sink to manage the thermal load from all of the electronics. It also ties the two halves of the housing together, preventing it from “oil-canning” under external pressure loads.
• T e investment casting process provided the ability to com- bine many parts into one and lower part cost and weight.
Hub Casting
Pier Foundry & Pattern Shop Inc. St. Paul, Minnesota
Material: Ductile iron. Process: Green sand. Weight: 90 lbs. Dimensions: 16 in. diameter, 5.5 in. height. Application: Mining.
• T e part replaced a 34-piece weldment to improve ease of manufacturing while holding up to the rigors of continuous mine operation where the hub rotates at 3,600 rpms. T e cast design saved the customer $76,000 in the fi rst year, reducing costs on the component by more than 50%.
• T e project brought 18,000 lbs. of cast iron production to the industry, and the customer has identifi ed two more hubs to convert into castings.
