In the Aerospace/Military/Firearms Category for MIM components, a Grand Prize has been awarded to ARC Group Worldwide for an enclosed striker used in the firing mechanism of a commercial handgun. The part is made in a 2-cavity mold, and strategic tool design and staging was implemented. Post-sintering, HIP, and heat treatment are performed to increase mechanical properties. The position of the tip to the primary body of the component is critical for part functionality. The parts are finished with an E-nickel coating.
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.
