This year, the winners in the 2021 Powder Metallurgy Design Excellence Awards competition included three components made using metal Additive Manufacturing. Organised by the Metal Powder Industries Federation (MPIF), the awards were announced during the International Conference on Powder Metallurgy and Particulate Materials (PowderMet2021), an event co-located with the Additive Manufacturing with Powder Metallurgy (AMPM2021) and Tungsten2021 conferences, held in Orlando, Florida, USA, from June 20–23, 2021.

In the design competition, a total of six Grand Prizes and sixteen Awards of Distinction are presented across the manufacturing categories of conventional Powder Metallurgy (PM), Metal Injection Moulding (MIM) and metal Additive Manufacturing.

A Grand Prize was awarded to Parmatech Corporation, California, USA, in the Hand Tools/Recreation Category for Metal AM components for a 316L stainless steel putter head and hosel, made for Cobra Puma Golf, and used in the King Supersport-35 golf putter. The MPIF explained that the use of Additive Manufacturing technology has allowed designers to place or remove material strategically, ensuring the optimal mass distribution and stiffness. This flexibility also allowed the production of both right and left-hand versions of the putter head and hosel without the need for tooling changes. The development of unique lattice structures also eliminated the need for supports during the sintering process.

In the Automotive – Transmission Category for MIM components, an Award of Distinction was given to ARC Group Worldwide for a worm gear used in a transmission locking mechanism. MIM processing was selected because of the complexity of the helical gear teeth and the adjacent shaft geometry. Custom staging furniture is used for sintering the parts which require no secondary operations to be functional in the mating assembly.

Indo-MIM Pvt. Ltd. received an Award of Distinction for an oil spray piston cooler using in automotive systems (Courtesy MPIF)

In the Automotive – Transmission Category for MIM components, an Award of Distinction was also presented to Indo-MIM Pvt. Ltd. for an oil spray piston cooler. The MIM-4605 parts are used in the engine of heavy vehicles and were previously made by machining. Holes are formed by two different slide pins at different angles in the tool, and the side core has to travel through the center pin with a delay mechanism.

Aerospace/Military/Firearms Category MIM

In the Aerospace/Military/Firearms Category for MIM components, an Award of Distinction was given to Indo-MIM Pvt. Ltd. for a frame chassis, part of a pistol assembly. The parts are made using MIM-17-4 PH in the H900 condition.

Prior to MIM the parts were machined from bar stock by the customer. The MIM parts meet 80% of the required part features with the remainder being machined by the customer, reducing the machining cycle by 70%.

Advanced Powder Products Inc. and its customer Savage Arms were presented with an Award of Distinction for a bolt handle used in a hunting rifle (Courtesy MPIF)

In the Aerospace/Military/Firearms Category for MIM components, an Award of Distinction was also given to Advanced Powder Products Inc. and its customer Savage Arms for a bolt handle for a hunting rifle. The part assists with loading the next round of ammunition and in removing the shell after it has been fired.

The complex curvature and intricate design presented challenges with moulding and sintering. MIM processing was able to convert a two-piece design machined from bar stock to a single piece MIM part.

Industrial Motors/Controls & Hydraulics Category MIM

In the Hardware/Appliances Category for MIM components, an Award of Distinction was awarded to Indo-MIM Pvt. Ltd. for a knob shaft, clutch, knob shield, core plug, core body, and control sleeve actuator used in door locks. The previously machined stainless-steel parts have intricate profiles, thin walls, multiple holes, blind threads, aesthetic requirements, and sectional differences adding to the complexity of the part.

ARC Group Worldwide also received an Award of Distinction for a key blade used in an electronic security system (Courtesy MPIF)

In the Hardware/Appliances Category for MIM components, an Award of Distinction was also presented to ARC Group Worldwide for a key blade used in an electronic security system. Sintering requires custom staging to minimise distortion of the delicate geometries critical to part functionality. The parts require two sizing steps to ensure twelve critical dimensions meet the customer specifications. Fitment to the mating part and the aesthetic appearance of the primary visual surface was essential.

Medical/Dental Category for MIM

In the Medical/Dental Category for MIM components, an Award of Distinction was given to ARC Group Worldwide for a pusher used in the ratcheting assembly for the consistent placement of high viscosity adhesives in incisions, used as an alternative to sutures or staples in surgical procedures. Strategic tool design, venting and a three-plate pin gate allow complete material fill of the complex part geometry, keeping distortion to a minimum and allowing tight profile and dimensional requirements to be maintained.

Alpha Precision Group and its customer Elite Biomedical Solutions were given an Award of Distinction for this component used with IV pumps (Courtesy MPIF)

An Award of Distinction has also been awarded in the Medical/Dental Category for MIM components to Alpha Precision Group – Metal Injection Molding and its customer Elite Biomedical Solutions for an LVP door latch for an IV pump. The component has a tight tolerance on the hole position for the assembled roller. In use, the roller is latched on to a mating component that the company also makes to complete the latch/hook mechanism. The parts are made in-house from start to finish and the machining and multi-stage assembly are considered value added to the customer.

Electronics/Electrical Components category MIM

An Award of Distinction was awarded to Indo-MIM Pvt. Ltd. for a ceramic sensor used in an electronic device (Courtesy MPIF)

In the Electronics/Electrical Components category for MIM components an Award of Distinction was awarded to Indo-MIM Pvt. Ltd. for a ceramic sensor used in an electronic device.
