From prototypes to mass production, powder metallurgy (PM) technologies like metal injection molding and metal additive manufacturing have been changing the manufacturing landscape across market segments.
Aerospace and defense have utilized PM technology for incredible innovations, the use of PM in the electronic and electrical market impacts our daily lives, and PM in the medical and dental field enhance patient care and quality of life every day.
It is with great pleasure that the Metal Powder Industries Federation announces the winners of the 2020 Powder Metallurgy Design Excellence Awards Competition in the special technologies market segment.
The Grand Prize in the Aerospace/Military/Firearms Category for MIM components, has been awarded to Advanced Powder Products Inc. for a trigger mechanism housing for a new 9- mm sub-compact pistol produced for O.F. Mossberg & Sons Inc. The component originally comprised two pieces (metal and plastic), and was re-designed as a single MIM part. Over 5,000 rounds were fired to test the part and no failures were observed.
Advanced Powder Products Inc. also received the Grand Prize in the Medical/Dental Category for MIM components, for a guide tube used in dental surgery. This extremely small part has very thin wall sections and a built-in impingement plate on the inner diameter of the tip. This impingement plate has a Gaussian curvature that can only be formed economically by metal injection molding.
Awards of Distinction
In the Aerospace/Military/Firearms Category for MIM components, an Award of Distinction has been given to Alpha Precision Group – Metal Injection Molding for a shroud that houses the firing pin and firing pin collar in a bolt-action rifle.
An Award of Distinction in the Aerospace/Military/Firearms Category for MIM components, has also been given to ARC Group Worldwide for lever actuators for vanes in a turbo-prop engine. The actuators control the angle of the variable inlet guide vanes and the variable stator vanes.
An Award of Distinction has been given to 3DEO in the Aerospace/Military/Firearms Category for metal AM components, for an anchor link used in a firearms application. A hybrid metal AM process is used to make the parts.
In the Medical/Dental Category for MIM components, an Award of Distinction has been given to MPP and their customer Coracoid for a buckle used in an implanted shoulder repair device. Several technologies were considered for making the part but MIM processing was the only one that produced a part that could withstand the stresses induced during the cinching of the device during surgery and the placement of the cleat.
An Award of Distinction has also been given in the Medical/Dental Category for MIM components to OptiMIM and their customer Atricure for one of two jaws of a surgical device for deploying a clip around a heart’s left-atrial-appendage. The mold produces two parts that are mirror images of one another.
An Award of Distinction has been made to ARC Group Worldwide and their customer Cutsforth Inc. in the Electronic/Electrical Components Category for MIM components, for a lower beam EZ change holder for removable brush holders. They are used in brush excitation maintenance on turbine generators in the nuclear, gas, coal, wind, and hydro industries.
