Abstract
A novel method and apparatus for forming an aluminum container with an exposed metallic insert in the closed end thereof with the aluminum and the secondary metal being coextruded during forming of the container. A particularly synergetic combination is achieved by selecting a spherical insert member and providing concave or depressed region in the bottom of the extrusion die mold to partially receive the spherical element. The aluminum flows around the major diameter of the spherical insert during coextrusion but leaves a bottom portion of the insert exposed for external welding to another component.
