Michigan is the heart of American vehicle manufacturing and one of the deepest industrial economies in the country, with six distinct clusters that all generate steady demand for industrial retractile, curly, and coiled cordage. The Detroit Three anchor a vehicle-assembly base that runs from Flint and Detroit to Sterling Heights and Dearborn. A vast tier-1 supplier network in Oakland, Macomb, and Wayne counties feeds those lines. EV and battery-cell production is scaling in Lansing and Holland. Metro Detroit hosts the nation's densest ground-vehicle defense cluster around the Army's research center in Warren. West Michigan is the office-furniture capital of the world. And a statewide machine-tool and industrial-automation base builds the equipment that all of the above run on. Each cluster carries its own engineering requirements — current rating, jacket compound, flex life, shielding, environmental exposure — and the Autac product line maps directly to all six.
Michigan is the global center of vehicle assembly. General Motors runs Flint Assembly (heavy-duty Silverado and Sierra trucks), the EV-dedicated Factory ZERO in Detroit-Hamtramck, and the 710-acre GM Technical Center in Warren. Ford builds the F-150 and F-150 Lightning at the Rouge complex in Dearborn and operates its world headquarters there. Stellantis assembles trucks and Jeep SUVs at Sterling Heights Assembly, Warren Truck Assembly, and the Detroit Assembly Complex, with North American headquarters in Auburn Hills. These plants run thousands of assembly-line tool drops, torque-tool feeds, and inspection-station power connections that must satisfy IATF 16949 supplier-quality and PPAP documentation requirements.
Typical Michigan applications in this segment:
Recommended Autac products: TPR-jacketed retractile cords in 14 AWG and 12 AWG, 3-conductor / 15A configurations cover most assembly-line drops; custom retracted lengths from 18" to 36" are standard. Step up to 10 AWG / 20A for higher-current torque tooling and test stations. Browse the Retractile Cords hub for stock part numbers, or use the Build Your Cord tool to specify a custom configuration for a vehicle-launch program. Lot traceability supports PPAP and IATF 16949 submissions.
Michigan hosts the densest automotive supplier network in North America. BorgWarner (Auburn Hills) builds propulsion and turbocharger systems. Lear (Southfield) makes seating and electrical-distribution systems. American Axle & Manufacturing (Detroit) produces driveline and metal-forming components. Adient (Plymouth), DENSO (Southfield), Magna operations, and hundreds of smaller stamping, molding, and machining shops across Oakland, Macomb, and Wayne counties supply the Detroit Three and transplant OEMs. Supplier plants run high-cycle assembly and test equipment where flex life, oil resistance, and traceability are non-negotiable.
Typical Michigan applications in this segment:
Recommended Autac products: SJOW and SOW UL types in 14 AWG to 10 AWG resist the cutting oils and coolants common in stamping and machining environments. For high-cycle robotic and material-handling applications, shielded retractile and coiled configurations protect signal integrity. Browse the Retractile Cords hub and Coiled Cords for shielded multi-conductor assemblies, and reference the conductor color charts for supplier-standard wiring schemes.
Michigan is scaling battery and EV production fast. Ultium Cells — the GM and LG Energy Solution joint venture — built a 2.5-million-square-foot battery-cell plant in Delta Township near Lansing. LG Energy Solution expanded its long-running Holland facility to produce lithium iron phosphate (LFP) cells for energy storage and for Ford. GM Factory ZERO in Detroit-Hamtramck builds electric trucks and SUVs, and Stellantis is retooling Sterling Heights for battery-electric pickups. Battery and EV manufacturing carries demanding electrical requirements: high-current assembly drops for cell-pack assembly, dry-room-compatible cordage, and high-voltage test-cell feeds rated for repeated thermal and electrical cycling.
Typical Michigan applications in this segment:
Recommended Autac products: 10 AWG / 20A retractile configurations handle the higher-current loads typical of battery assembly and test cells. Auta-Prene thermoset rubber and TPR jackets resist the coolants and electrolyte residues common in EV production. Browse the Retractile Cords hub for stock high-current configurations, and use Build Your Cord to specify retracted length, extension ratio, and termination for your line.
Metro Detroit hosts the densest ground-vehicle defense cluster in the country. The U.S. Army DEVCOM Ground Vehicle Systems Center (GVSC, formerly TARDEC) in Warren is the military's R&D hub for ground systems, anchored alongside U.S. Army TACOM at the Detroit Arsenal. General Dynamics Land Systems builds Abrams tanks and Stryker vehicles in Sterling Heights, and BAE Systems runs land & armaments programs in the Macomb area. Roughly two-thirds of Michigan's defense work is concentrated in Sterling Heights and surrounding Macomb County. These programs demand durable, traceable power and signal delivery to integration fixtures, test stands, and ground support equipment that must satisfy ITAR, Buy American, and defense supplier-quality requirements.
Typical Michigan applications in this segment:
Recommended Autac products: TPR and Auta-Prene-jacketed retractile cords in 12 AWG and 10 AWG cover most integration-line and test-stand drops; custom retracted lengths from 18" to 48" are standard. For signal and control applications, shielded 18 AWG and 16 AWG configurations are available. Browse the Retractile Cords hub or use Build Your Cord for a program-specific configuration. Autac is a US-only manufacturer with a US supply chain, which simplifies ITAR and Buy American supplier qualification.
Grand Rapids and West Michigan are the office-furniture capital of the world. Steelcase (Grand Rapids) is the largest office-furniture maker in the United States. MillerKnoll — the parent of Herman Miller — is based in Zeeland, and Haworth manufactures in Holland. These makers run high-mix metal-fabrication, powder-coat, upholstery, and assembly lines, plus a regional base of contract manufacturers, plastics molders, and metal stampers across Kent and Ottawa counties. Furniture and light-industrial assembly lines need cordage that retracts cleanly out of work cells, holds up to constant tool motion, and color-codes to plant standards.
Typical Michigan applications in this segment:
Recommended Autac products: Curly cords and retractile cords in 16 AWG to 12 AWG with TPR or PVC jackets are the workhorse for assembly-cell hand tools and torque tools. For finishing and welding environments, SJOW jackets add oil and abrasion resistance. Browse Curly Cords for high-flex tool builds and Cord Sets for custom-terminated assemblies, with plant-standard color coding documented on our Color Charts.
Michigan's machine-tool, robotics, and industrial-automation base builds and integrates the equipment the rest of the state's plants run on. FANUC America operates its North American robotics headquarters in Rochester Hills. KUKA runs automotive-systems operations in Sterling Heights and Shelby Township. Hundreds of machine builders, tool-and-die shops, and systems integrators across metro Detroit and West Michigan build welding cells, CNC machining centers, and material-handling automation. Integration and machine-build environments need flexible, durable cordage that survives constant motion on robot arms, gantries, and moving tooling.
Typical Michigan applications in this segment:
Recommended Autac products: High-flex curly and coiled cords in 18 AWG to 14 AWG support millions of flex cycles on robot arms and pendants; shielded configurations protect signal integrity in VFD- and servo-heavy cells. For higher-current machine power, 12 AWG and 10 AWG retractile cords in SOW and SJOW jackets handle the load. Browse Coiled Cords for shielded multi-conductor assemblies and Curly Cords for high-flex pendant builds.

Need a configuration that is not in the standard catalog? Michigan vehicle-launch teams, EV-and-battery startup engineers, and OEM tooling groups regularly use our Build Your Cord tool to specify prototype cords for new equipment platforms. Specify conductor count (2 to 10), gauge (26 AWG to 10 AWG), voltage and current rating, retracted length (12" to 48" and beyond), extension ratio (1:3 to 1:7), jacket compound and color, optional shielding, and termination type — and we handle design, tooling, and manufacturing from a single Connecticut facility. Quote turnaround on a custom build is typically one to three business days; most custom orders ship in 4 to 6 weeks. There is no minimum order quantity, which makes it practical to validate a design with a 5- or 10-piece pilot before committing to a production run — a pattern that works especially well for Michigan's launch-driven automotive, EV, and tooling programs.
From North Branford to Detroit, Grand Rapids, Warren, Sterling Heights, Lansing, Flint, Dearborn, Ann Arbor, Auburn Hills, Holland, Zeeland, and every Michigan destination in between, Autac ships standard ground freight in about 2 business days. Stock catalog cords typically leave our Connecticut dock within one business day of order entry. Total door-to-door turnaround for Michigan stock orders runs 3 to 4 business days end-to-end. For time-critical projects — vehicle-launch tooling, EV-line startups, defense program builds — expedited freight can compress door-to-door turnaround further. Custom-engineered cords ship as soon as production completes, typically 4 to 6 weeks from design sign-off.
Domestic-only freight means no customs paperwork, no broker fees, no cross-border delays, and no surprises at the receiving dock — a meaningful advantage over imported cordage and a clean fit for Buy American and USMCA content requirements common in automotive and defense supply chains. For high-volume Michigan accounts, we coordinate scheduled releases against blanket POs to keep production lines stocked without distributor lead-time stack-up. Smaller Michigan OEMs, startups, and contract manufacturers get the same direct-from-factory pricing as the largest accounts — pricing is based on configuration and volume, not customer-tier negotiations.
Setting up a Michigan account takes a single phone call or quote request. Our sales team handles credit-application paperwork, vendor-onboarding submissions, supplier-quality surveys (PPAP, FAI, ISO 9001, IATF 16949-aligned documentation, defense ground-vehicle supplier qualification), W-9 or diversity-certification documentation, and any Michigan-specific paperwork (resale certificates, supplier registrations) as part of standard onboarding. Existing Autac customers expanding into Michigan operations can extend their account to additional ship-to addresses without re-qualifying.
