MPI Corporation

What MPI Corporation does

MPI Corporation is a privately held investment holding company founded in 1975 as Materials Processing, Inc. in Indiana and headquartered in Logansport. Through wholly owned subsidiaries — most notably Small Parts Inc. and HTI (Haughton Technology Inc.) — the company manufactures metal formed components for four end-markets: automotive, appliance, electrical distribution, and consumer electronics. Core capabilities across the portfolio include flat roll material servicing and distribution, metal stamping, heat treating, and other finishing processes. The company has operated continuously for over 60 years and positions itself as a stable, long-term owner of industrial manufacturing businesses rather than a scaling technology platform.

The business model is structured as a B2B holding company: MPI Corp provides supporting infrastructure, counsel, and collective talent deployment to its operating subsidiaries, which generate revenue through direct sales of manufactured metal components to industrial OEM customers. Pricing is not publicly disclosed and is presumably quote-based, varying by order specifications, volume, and individual customer contracts. Distribution occurs through direct supply relationships rather than channel partners, and operating geography is concentrated in the Midwest USA with no global footprint claim.

The public information footprint is deliberately limited. No leadership team is disclosed on the company website, no customer logos are named, no external investors or funding rounds are listed, and no certifications, patents, or formal partnerships are documented in available sources. The careers page lists "no job openings" at time of capture, and the company's stated employee value proposition emphasizes stability, an on-site health clinic, and 60+ years of operating history rather than growth or expansion signaling.

Direct peers

• Anchor Manufacturing Group: Cleveland-based metal stamping and chassis component supplier to automotive and industrial OEMs. Comparable in process depth (stamping, welding, assembly) and customer mix to MPI.
• Trans-Matic Manufacturing: Privately held Midwest metal stamping company producing precision deep-drawn and progressive-die stampings. Closely mirrors MPI's stamping focus and industrial OEM customer profile.
• Stamped Products: Indiana-based metal stamping and assembly supplier serving appliance, automotive, and industrial markets. Geographic and customer-segment overlap with MPI is unusually direct.
• Acme Industries: Mid-tier US metal stamping and assembly operation serving automotive, appliance, and industrial markets. Direct competitor profile in scale, geography, and service offering to MPI.
• Shiloh Industries: Automotive-focused metal forming and lightweighting solutions provider with stamping, joining, and acoustic capabilities. Highly comparable to MPI in automotive exposure and integrated metal processing.
• Mayville Engineering Company (MEC): Publicly traded US metal forming and stamping manufacturer serving automotive, heavy truck, agriculture, construction, and powersports OEMs. Direct peer in scale, vertical mix, and customer base to MPI's subsidiaries.

Emerging players
