What International Manufacturing & Assembly does

International Manufacturing & Assembly (IMA) is a privately held U.S.-headquartered contract manufacturer specializing in high-volume, tight-tolerance aluminum and steel components and sub-assemblies. Founded around the mid-2000s and headquartered in Royal Oak, Michigan, with a stated 501-1000 employee base, IMA operates a multi-continent footprint with sister plants across America, Europe, and Asia delivering to Tier 1 and Tier 2 automotive suppliers globally.

The company's integrated capability stack spans aluminum extrusions in alloys 6063, 6005, 6061, 6060, and 6082, aluminum and steel stamping (progressive, transfer, line die), CNC fabrication (milling, punching, hydraulic stretch bending, cutting, welding), smart automated assembly with robotic production lines and integrated quality control, and end-to-end surface treatment (brushed Class A, anodizing, E-coat/KTL, powder coating). This vertical integration supports tight tolerances on thin-walled profiles — including Class-A visible components (running boards, window guide rails, sunroof rails, luggage cover cassettes, tonneau covers) and structural parts (battery housings, trunk panel structure, engine cradles, B and C pillars).

IMA sells primarily via direct B2B field sales responding to customer RFQs, with quote-based pricing tailored to customer pricing targets and timing. Revenue is generated through contract-manufacturing volumes across four end markets: automotive (15+ named OEMs including VW, Toyota, BMW, Mercedes, Ford, GM, Honda, Audi, Porsche, Bentley, Rivian, Stellantis, Volvo, Renault, Peugeot), solar (panel clamps, frames, assemblies), power distribution / data centers (bus bars, PDU profiles), and industrial. IMA cites an 86% repeat customer rate and 8.6M+ vehicles equipped with IMA parts as commercial evidence, though financial metrics, ownership structure, and headcount detail are not publicly disclosed.

Core offering

IMA manufactures custom, high-volume aluminum extrusions and steel stampings, then transforms them into finished components and sub-assemblies through in-house fabrication (CNC milling, bending, welding), robotic automated assembly, and surface treatment (anodizing, e-coat, powder coating). Output is supplied as Tier 1/Tier 2-ready parts for automotive, solar, and data center/power distribution programs.

Product overview

IMA is a high-volume manufacturing company specializing in custom aluminum and steel components and sub-assemblies. The company operates as a single unified offering with multiple integrated manufacturing capabilities: Aluminum Extrusions (tight tolerance profiles in various alloys), Stamping (progressive, transfer, and line die capabilities for aluminum and steel), Fabrication (CNC milling, punching, bending, welding), Smart Automated Assembly (robotic production lines with quality control), and Surface Treatment Solutions (anodizing, e-coat, powder coating). These capabilities serve four main product categories: Automotive Class-A components (visible exterior parts), Automotive Structural components (battery housings, structural panels), Solar Components (clamps, frames, assemblies), and Data Center Power Distribution components (bus bars, PDU profiles). The company operates manufacturing facilities in America, Europe, and Asia, delivering globally to Tier 1 and Tier 2 automotive suppliers and industrial clients.

Broad incumbents

• Superior Industries International: North American supplier of aluminum cast and forged wheels plus suspension and structural components to global OEMs — comparable customer base and aluminum-intensive automotive component focus, though different part categories.
• Kaiser Aluminum: U.S.-based semi-fabricated specialty aluminum mill products producer serving aerospace, automotive, and industrial markets, including extrusions for automotive applications — broader but a competitor in the extrusion category.
• Magna International: World's largest Tier 1 auto supplier with broad capabilities across aluminum body, chassis, and EV structures — overlaps IMA in aluminum extrusions and assemblies and is the consolidator that already acquired direct peer Shiloh Industries.
• Constellium: Global aluminum products manufacturer serving automotive (body sheet and extrusion), aerospace, and packaging — overlaps with IMA in extruded automotive components and in aluminum-intensive EV applications.
• Novelis: Global leader in aluminum rolling and recycling, a major supplier of automotive body sheet and structural aluminum — overlaps with IMA at the OEM and aluminum-content level, with greater scale and upstream integration.
• Norsk Hydro: One of the world's largest integrated aluminum producers with a substantial extruded solutions business serving automotive, solar, and electrical applications — broader and upstream of IMA, but directly competes in the extrusion segments IMA targets.

Direct peers

• Shiloh Industries: Specialist in aluminum and steel stampings, extrusions, and engineered welded assemblies for automotive OEMs, with deep exposure to tight-tolerance, thin-walled Class A components — directly comparable product mix to IMA.
• Gestamp: Global Tier 1 metal automotive supplier specializing in aluminum and steel body-in-white, chassis, and EV battery enclosure stampings and assemblies — directly comparable in product, customer, and vertical integration.
• Martinrea International: Tier 1 supplier of lightweight aluminum structures, stampings, and assemblies for global OEMs, including EV battery enclosures — same customer base, same aluminum content-per-vehicle exposure, and similar mid-cap private/public profile.
• Benteler International: European-headquartered Tier 1/2 supplier of aluminum and steel structural and chassis components for OEMs, with multi-continent manufacturing — closely mirrors IMA's global manufacturing strategy and product portfolio.
