This paper describes a new concept for a Ford F-150 light truck Front End Support Assembly (FESA) based on a one-piece die cast structural magnesium component. This new FESA reduces the number of parts and therefore the complexity of manufacturing and assembly, it integrates a multi-piece weldment assembly into a die cast part, and it considerably decreases mass compared to its steel counterpart. The design also reduces FESA cost. Major design criteria included corrosion protection, crashworthiness assessments, Noise Vibration Harshness (NVH) performance, durability and Ford assembly plant constraints. Die casting requirements included feasibility for large volume production, coating strategy and assembly constraints. The resulting design used the flexibility present in a magnesium die-casting that would not be possible using conventional steel stampings and assembly techniques.

Ford GT 2005 vehicle was designed for performance, timing, cost, and styling to preserve Ford GT40 vintage look. In this vehicle program, many advanced manufacturing processes and light materials were deployed including aluminum and magnesium. This paper briefly explains one unique design concept for a Ford GT instrument panel comprised of a structural magnesium cross-car beam and other components, i.e. radio box and console top, which is believed to be the industry's first structural I/P from vehicle crash load and path perspectives. The magnesium I/P design criteria include magnesium casting properties, cost, corrosion protection, crashworthiness assessments, noise vibration harshness performance, and durability. Magnesium die casting requirements include high pressure die cast process with low casting porosity and sound quality, casting dimensional stability, corrosion protection and coating strategy, joining and assembly constraints.
