The most innovative, effective, and impactful cast-metal designs of the past year were recognized during CastExpo ’08.
The 2008 Engineered Casting Solutions and AFS Casting Competition awarded nine cast components as the best designs for 2008. The AFS named an overall winner, four Best-in-Class winners, and four honorable mentions. The winning product was produced by Carley Foundry Inc. in Blaine, MN and oil tank for Harley Davidson. The component houses and circulates oil throughout the new Harley Rocker’s operating system, and it is an important element of the cycle’s cosmetic appeal. The component was cast in A356-T6 aluminum using semi-permanent molding and it weighs 9.25 lbs. In addition to its “aestically pleasing” attributes, it offers better heat resistance than the alternative proposals a plastic design and a multi-piece fabrication.
Contech Wins Twice in 2008 International Die Casting Competition
Contech U.S., a division of Marathon Automotive Group, won two awards in the 2008 International Die Casting Competition, sponsored by the North American Die Casting Associaiton. The annual competition recognizes outstanding castings based on their design, quality, cost savings, ingenuity, innovation, and industry-changing potential.
A rear knuckle structure for the Jaguar XK8 won the Aluminum, Squeeze/ Semi-Solid award. The large, complex component was produced using Contech’s P2000 squeeze casting process. This is the third straight year that Contech has won the award in this category, and the fifth time since 2001.
A rear-axle thrust rod for the BMW X5 won the award for the “Aluminum Die Casting under 1 lb.” category. The rod, fully designed by Contech, replaced a multiple-part steel assembly and provided an approximate 50% weight savings for the automaker.
“Our close working relationships with our customers, combined with our engineering expertise enabled Contech to optimize the customer’s original designs for our processes, and to bring these new components to market successfully,” said president Mark Hunter.
Best in Class Winners

Piad Precision Casting Corp. developed
this material handling steering/linkage
assembly, a brass permanent-mold
chill casting that replaced a weldment that
consisted of 10 pre-fabricated pieces, 19
weld joints, and four bushings.
Dotson Iron Castings is the developer
of this agri-speed hitch, an assembly
of austempered ductile iron and
ductile-iron green sand castings that was
reverse-engineered from the customer’s
weldment, resulting in a 30% weight
reduction and 40% cost reduction.
Castalloy Corp.’s design for a static
mixer tube is a 124-lb. white iron no-bake
sand casting, a conversion from a seven-piece fabrication that eliminates all assembly
labor and makes it possible to incorporate
strategic thickening of wear areas.
Denison Industries developed this main
transmission housing for a military contract,
converting a multi-piece assembly
into a 200-lb casting. The A356-T71 aluminum
no-bake sand casting eliminated
tubing, hydraulic lines, and passageways.
2008 Honorable Mentions:
Citation Columbiana’s multifunction
bracket/towing eye for Volvo is a 21-lb.
ductile-iron lost-foam casting that eliminated
the machining and heat treating required
on previous bracketdesignss.
General Motors & Diversified Machine’s
design is an engine cradle for the
Cadillac CTS, a 33.5-lb. vacuum riserless/
pressure riserless casting that was
poured in A356 aluminum and welded
to four aluminum extrusions to form the
engine cradle.
Trilore Technologies developed this automotive
aftermarket intake manifold, a
13-lb. A356-T6 aluminum casting that is
converted from a plastic molding.
Eck Industries used the ablation process
to make a 4.9-lb, A356-T6 aluminum
rear motorcycle frame, with enhanced mechanical
properties in its thin sections.
