PMG Indiana is permanently closing its Columbus, Indiana auto parts plant by the end of 2026, cutting 150 jobs, according to a WARN notice the German-owned company filed on Sept. 2, 2026. The closure is another sign of the pressure squeezing traditional internal-combustion parts suppliers as automakers keep shifting toward electrified powertrains.
Key Points
- PMG Indiana, a subsidiary of Füssen, Germany-based PMG Holding GmbH, filed its Worker Adjustment and Retraining Notification with the Indiana Department of Workforce Development on Sept. 2, 2026.
- 150 workers will lose their jobs, with layoffs beginning Nov. 1, 2026, ahead of a final plant shutdown by Dec. 31, 2026.
- The 186,000-square-foot facility at 1751 Arcadia Drive makes custom powder-metal powertrain components and sub-assemblies for major automotive suppliers.
What The Plant Made — And Who It Supplied
PMG Indiana’s Columbus facility specialized in powder-metallurgy components: parts formed by compacting and sintering metal powder rather than casting or machining solid metal, a process commonly used for gears, sprockets and other powertrain hardware in traditional combustion engines. According to The Republic, the plant supplied automotive manufacturers including Stellantis, Hitachi, Valeo, Schaeffler, ZF, Exedy and Hanon.
The plant has a long history in Columbus. It opened in 1987 as Diamet Corporation, a subsidiary of Mitsubishi Materials, and PMG consolidated its Midwest manufacturing operations there in 2007. Its workforce has shrunk steadily since then — from 365 employees in 2014 down to the 150 who remain today, a decline of nearly 60%, per local reporting on the closure.
What It Signals For Suppliers
The shutdown reflects a broader industry shift. Powder-metal parts like the ones PMG Indiana produced are used heavily in gasoline and diesel engines and transmissions — components that simply don’t exist in the same form in a battery-electric drivetrain. As automakers redirect capital toward EV platforms, legacy suppliers tied almost exclusively to combustion-engine hardware are facing shrinking order books even as the broader powder-metallurgy market, driven by other industrial uses, is still projected to keep growing globally through the next decade.
PMG Indiana’s closure did not happen in isolation. It landed the same week Indiana RV manufacturer Forest River announced a separate round of 105 layoffs, adding to a string of manufacturing job losses across the state’s industrial base this year.
What Happens Next
Displaced workers are eligible for state employment transition assistance through the Indiana Department of Workforce Development, which tracks the WARN filing and connects affected employees with job placement and retraining resources. Layoffs begin Nov. 1, 2026, with the plant fully shut down by year’s end.
