METHOD AND SYSTEM FOR JOINING METAL COMPONENTS BY OVERMOLDING

摘要

A novel system and method for joining metal components to form assemblies, the components having a metal joint overmolded onto them. The metal joint is overmolded from a thixotropic alloy, such as a magnesium-based alloy, which is injected into a joint cavity in a joining die into which the components to be joined are loaded. The joint is formed over and/or through flanges or other features provided on the components and results in a structural joint which can also be liquid and/or air tight. The system and method permit the joining of components formed of different materials, formed by different processes and./or formed of different gauge materials.
