Best Designs of Cast Expo ’08
The Cast Expo ’08 recognized the most effective and innovative cast designs developed during the last year. Nine cast components were selected as the best designs of the year by the 2008 Engineered Casting Solutions and AFS Casting Competition. The AFS nominated an overall winner, 4 Best-in-Class winners, and 4 honorable mentions.
An oil tank for Harley Davidson, developed by the Carley Foundry Inc. in Blaine, MN, was named as the winning product. The product houses and circulates oil across the new Harley Rocker’s operating system, and it is a critical element of the cycle’s cosmetic look. The product was cast in A356-T6 aluminum using semi-permanent molding and weighs 9.25 lbs. In addition to its aesthetically pleasing design, it provides superior heat resistance than the available options – a plastic design and a multi-piece fabrication.
Contech Wins Twice in the International Die Casting Competition’08
A division of Marathon Automotive Group, Contech U.S., won two awards in the 2008 International Aluminum Die Casting Competition, sponsored by the North American Die Casting Association. It is an annual competition that acknowledges outstanding castings depending on their design, effectiveness, cost savings, ingenuity, innovation, and the potential to change industry trends.
A rear knuckle component for the Jaguar XK8 was named the winner of Aluminum, Squeeze/ Semi-Solid award. It was a large, complex component designed using Contech’s P2000 squeeze casting method. This is the 3rd consecutive year that Contech has won the award in this category, and the 5th time since 2001.
It won the 2nd award under the “Aluminum Casting under 1 lb.” category, for a rear-axle thrust rod designed for the BMW X5. Fully designed by Contech, the rod replaced a multiple-part steel assembly and provided about 50 % weight savings for the automaker.
Best in Class Winners
Material Handling Steering / Linkage Assembly
This is a material handling steering / linkage assembly designed by the Piad Precision Casting Corp The component is a brass permanent-mold chill casting, which replaced a weldment that comprises of ten pre-fabricated pieces, nineteen weld joints, and four bushings.
Agri Speed Hitch
CNM Iron Castings has developed this agri-speed hitch, which is an assembly of austempered ductile iron and ductile-iron green sand castings, which was reverse-engineered from the customer’s weldment. The component has resulted in reduction of 30% in weight and 40% in cost.
White Iron No-Bake Sand casting
This is a 124-lb. white iron no-bake sand casting, designed by the Castalloy Corp. for use as a static mixer tube. Conversion from a 7 piece fabrication, the component eliminates all assembly labor and allows the designers to incorporate strategic thickening of wear areas.
Main Transmission Housing
Designed by Denison Industries, this is a main transmission housing for a military contract, transforming a multi-piece assembly into a 200-lb casting. The component is designed using A356-T71 aluminum no-bake sand that eliminates tubing, hydraulic lines, and passageways.
Multifunction Bracket / Towing Eye
This is a 21-lb multifunction bracket/towing eye designed for Volvo by Citation Columbiana. Developed using ductile-iron lost-foam casting process, the component eliminates the machining and heat treating required on earlier bracket designs.
Vacuum Riserless / Pressure Riserless Casting
Developed by General Motors & Diversified Machine, this component is a 33.5-lb. vacuum riserless/ pressure riserless casting designed to serve as an engine cradle for the Cadillac CTS. The casting was poured in A356 aluminum and welded to 4 aluminum extrusions to create the engine cradle.
Automotive Aftermarket Intake Manifold
This is an automotive aftermarket intake manifold designed by the Trilore Technologies. The component is a 13-lb. A356-T6 aluminum casting, converted from a plastic molding.
Aluminum Rear Motorcycle Frame
Eck Industries make use of the ablation process to design this 4.9-lb, A356-T6 aluminum rear motorcycle frame. The component provides improved mechanical properties in its thin sections.
