What Marion Manufacturing does

Marion Manufacturing (legally Marion Tool & Die, Inc., dba Marion Manufacturing) is a privately held, family- and women-owned precision CNC machining and metal fabrication company founded in 1996 in West Terre Haute, Indiana. It produces custom precision-machined components for regulated, high-tolerance industrial end markets — aerospace, satellites, defense, energy, heavy equipment, and agriculture. The company operates two facilities: a West Terre Haute, IN headquarters (a 5.5-acre site with roughly 40,000 sq ft of combined manufacturing space and a small office) and a Morton, IL location acquired via a 2015 merger with Morton Machining. Combined headcount exceeds 150 employees.

Operationally, Marion delivers four integrated service lines: turn-key manufacturing (new process development, tooling design, special processes such as coating, welding, heat treat and brazing, and Level 300 cleanroom assembly), multi-axis machining (3-, 4-, and 5-axis CNC on Haas, Mazak, Mori-Seiki and Matsura platforms with tolerances to ±0.0001"), rapid prototyping and reverse engineering, and in-house engineering/CNC programming using MasterCam, Unigraphics NX, Pro/ENGINEER, SolidWorks and Autodesk. The company works exotic alloys (Inconel, Titanium, Haynes 188, L605, single crystal, TMZ) and runs a certified quality system — AS9100D and ISO 9001:2015 — supported by four active CMMs (NIST-traceable, ASME B89-certified, repeatability to 1.3 microns) and structured advanced quality planning including First Article Inspection.

The business model is direct B2B enterprise field sales of made-to-order machined parts, with volumes ranging from single prototypes to thousands of replications. Pricing is quote-based per customer specification and not publicly disclosed; revenue is generated through one-time part-production contracts rather than recurring licensing. Go-to-market is domestic (US-only), relationship-led, and reputation- and certification-driven, with visibility supported by the company website, PR/case studies (e.g., Conexus Indiana), and industry-association membership. A signature commercial milestone is a $25M U.S. Navy contract (awarded September 2021, jointly with Augustine Die & Mold Inc., completion expected June 2026) supporting naval maintenance, overhaul and modernization through Portsmouth Naval Shipyard.

Core offering

Marion Manufacturing provides custom CNC precision machining and turn-key manufacturing services, producing complex metal components from exotic alloys for aerospace, defense, energy, heavy equipment, and agriculture customers. Services span new process development, tooling design, multi-axis machining (3-, 4-, and 5-axis) to tolerances of +/-.0001, special processes (coating, welding, heat treat, brazing), Level 300 cleanroom assembly, and CMM-based quality inspection.

Product overview

Marion Manufacturing is a privately held, Women-Owned precision CNC machining company offering four integrated core services: Turn-Key Manufacturing (end-to-end production with special processes and cleanroom assembly), Multi-Axis Machining (3-, 4-, and 5-axis CNC with tolerances to ±0.0001"), Rapid Prototyping (including reverse engineering from legacy parts), and Engineering Services (CNC programming with MasterCam, Unigraphics, SolidWorks, and Autodesk). Quality assurance is delivered through CMM Inspection (4 active CMMs plus portable arms, ASME B89/NIST certified) and Advanced Quality Planning. The portfolio spans aerospace components (high-temperature alloys, turbine parts), satellite subassemblies, defense/military parts, energy equipment (valves, pumps, structural components), heavy equipment (gear blanks, wear plates, shaft bearings), and agricultural machinery (engine blocks, gear cases, suspension components).
