The sweet spot for MIM firearms components is small, complex, high‑volume parts that are difficult or wasteful to machine. In firearms, this typically includes internal lock work (sears, triggers, hammers), sights, extractors and ejectors, magazine releases and many safety components. These parts often have small radii, thin features and multiple function‑critical surfaces that must interact repeatably with machined or forged mating components. 

DSH Technologies Chief Metallurgist, Bryan Sherman, has 25+ years of hands-on experience supporting the powder metallurgy, metal injection molding, and sinter-based additive manufacturing industry. From prototype to production, Bryan's career in captive parts manufacturing, research, furnace technologies, recipe development, and debinding excellence is second to none. As a major contributor to the market, Bryan continues to use his voice to educate the current and next generation. Learn more about Bryan and check out our Powder Metallurgy Masterclass series!

The DSH Advantage reframes traditional vendor support into a forward-looking partnership: a subscription-based, expert-led program that injects elite metallurgical capability directly into your decision-making rhythm. It’s engineered to turn technical risk into predictable outcomes and to align materials strategy with corporate priorities for growth, reliability, and margin expansion.

With decades of experience in sintering, Elnik Systems understands the challenges, nuances, and process controls required to achieve repeatable, high-quality results. Rather than keeping this expertise internal, we launched DSH Technologies in 1999, which has since become a global authority in sintering services, education, metallurgy, process control, and troubleshooting.

From the Chief Metallurgist’s Desk, Bryan Sherman shares his decades of metallurgical expertise in an original content series designed to educate, entertain, and impact. From troubleshooting to training, testing to first-hand experiences, Bryan offers world-class guidance and real-world examples to better support the powder metallurgists, MIM and sinter-based additive manufacturing shops.

These following tips are written for MIM shops, metal parts makers, and fellow metallurgists: practical, actionable guidance to reduce scrap, improve sintered density and mechanical properties, and avoid surprises during debind and sinter cycles.
