Abrégé

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.

Abrégé

A system and method for controlling the molding of products from semi-solid materials tests feedstock materials prior to molding. The actual temperature at which a desired percentage of solids will be obtained in the molding shot is determined by the testing and the molding operation is performed with the molding shot substantially at the determined temperature. In one embodiment, the feedstock is tested at appropriate intervals, such as at each change of feedstock lot. In another embodiment, the feedstock is tested at regular intervals during the molding process and an open loop or closed loop control system is employed to alter the process temperature, as needed, during molding operations.
