Title: Allen N. Niemi and His Metal-Alloy Injection-Molding Patent.
Introduction
Allen N. Niemi is an inventor associated with Houghton, Michigan. His patent work includes an invention for injection molding metal alloys in a semi-solid, thixotropic state.
Latest Patents
The available information identifies one patent for Niemi: Method and Apparatus for the Injection Molding of Metal Alloys. The invention maintains an alloy in a semi-solid state—above its solidus temperature and below its liquidus temperature—while shearing it in a reciprocating extruder. The resulting thixotropic slurry is injected into a mold to form a product. After the injection stroke, a portion of the remaining alloy solidifies in the nozzle, sealing it.
Career Highlights
Niemi’s listed professional associations include The Dow Chemical Company and Regan D. Wieland. His patent describes a process designed to control the alloy’s state during injection and seal the extruder nozzle after molding.
Collaborations
Niemi’s listed coworkers include Norbert L. Bradley and Regan D. Wieland. Regan D. Wieland is also named among his professional associations.
Conclusion
Allen N. Niemi’s documented patent contribution focuses on injection molding metal alloys as a semi-solid slurry, with a nozzle-sealing step that completes the process.
