Award-Winning Powder Metal Parts

The Metal Powder Industries Federation is a federation of six trade associations representing various aspects of powder metallurgy (PM), metal powders, and particulate materials with a mission of advancing the interests of the metal powder producing and consuming industries.

Winners of the 2017 Powder Metallurgy (PM) Design Excellence Awards Competition, sponsored by MPIF were announced at the POWDERMET2017 International Conference on Powder Metallurgy & Particulate Materials. Receiving grand prizes and awards of distinction, the winning parts are outstanding examples of powder metallurgy’s precision, performance, complexity, economy, innovation, and sustainability. The winning parts show how customers from around the world are taking advantage of PM’s remarkable design advantages.

An Award of Distinction in the Aerospace/Military Category was earned by ARC Group Worldwide, Longmont, Colorado, for a metal injection molded (MIM) latch made from MIM-4140 low-alloy steel for Sig Sauer Inc. The internal latch drives a subassembly for the telescoping feature of the collapsible stock on MCX and MPX rifles. The part was designed for metal injection molding as it could not be economically made using any other fabrication method.

An Award of Distinction in the Hand Tools/Recreation Category went to Indo-MIM Pvt. Ltd., India, for a set of metal injection molded (MIM) parts—barrel block, gas block, bolt catch, 7.62 NATO mag conversion bar, ejector retainer, and extractor link—that go into an MDR rifle made by Deserttech. The MIM-designed parts replaced ones that were machined, and reduced the cost by 30% while manufacturing lead-time was cut in half. MIM is one of the PM-based technologies, that forms metal powders into precision components used in applications such as auto engines and transmissions, hardware, industrial machinery, sporting goods, defense, and firearms.

I have two new books that have just been listed on Both are available in Paperback and Kindle versions.

The first is “American Odyssey” and tells the Story of my Grandfather’s immigration from Poland to The U.S and covers his experience as an immigrant and in WW1. It is a tribute to all the people from all over the world that left their old lives and experienced passing through Ellis Island, Learning the Language while living with family and working menial jobs just to become Americans and secure a future for their children. It also follows him through the chaos of the first months of the War when we were unprepared, the trip to France with the first contingent of American troops , Training and introduction to trench warfare. He experiences the fear of death the painful exposure to Mustard Gas and being wounded.

The second book, “Chicago Rhapsody” is the first in a series of a smart mouth Private Detective who manages to fail at everything he tries until he becomes a cop. Along the way he picks up a K-9 partner who is his equally independent alter ego. If you like snappy dialog, funny situations, shoot outs, and a bit of mystery I think you will find this one right up your dark alley.
