Abstract
A component formed of metal, such as aluminum, and including a hollow core is provided. The component can be used as a cradle, rail, A-pillar, twist axle, control arm, or shock tower, for example. The component is manufactured by a high pressure vacuum die casting (HPVDC) process. To form the component with the hollow core, a blown or stamped hollow glass core is placed in a die cavity of the high pressure vacuum die casting apparatus, and the metal is melted and injected into the die cavity around the glass core. The metal is then cast and solidifies around the glass core. After the casting process, the glass core can be shattered, removed from the cast component, and recycled.
