This worm gear won an award in the Metal Powder Industries Federation (MPIF) 2021 PM Design Excellence Awards Competition. These innovative, powder metallurgy (PM) automotive transmission locking mechanism components were manufactured by the metal injection molding (MIM) process. MIM processing was selected because of the complexity of the helical gear teeth and the adjacent shaft geometry.
The winners in the 2021 Powder Metallurgy (PM) Design Excellence Awards competition, sponsored by the Metal Powder Industries Federation (MPIF), demonstrate outstanding examples of PM’s diversity. From electric vehicles to golf putters, these components use PM’s flexibility to push forward new concepts and process controls to demonstrate the inexhaustible well of capabilities PM can marshal in the service of component design.
