Cylinder Head Allows Complexity


Cast Component: V-Rod cylinder head.


Material: Aluminum Alloy AS5U3G (a proprietary alloy in the aluminum 300 series).


Process: Low-pressure permanent mold.


Application: Engine cylinder head for a power sports motorcycle.


Casting Supplier: ATEK Precision Cast- ings, New Hampton, Iowa.


Customer: Harley-Davidson.


• T e cylinder head combines complex, internally cored geometry with a highly cosmetic exterior surface.


• Originally created through gravity casting, the low-pressure permanent mold process allows the component to meet required mechanical strength, pressure tightness and wall thickness (0.125 in.), in addition to removing core sand from parts and water jacket passages.


• Solidifi cation under 3.15 psi pressure delivered superior casting soundness. 20 | METAL CASTING DESIGN & PURCHASING | Sept/Oct 2012
