Tier 1 and Tier 2 assemblies for seating and interior systems — IATF 16949 certified, manufactured in Mexico.
Opening
C.A. Spalding has been a Tier 1 and Tier 2 supplier to the automotive industry for over 50 years. We manufacture mechanical and electromechanical assemblies for seating and interior systems — supplying tested, installation-ready components to Adient, Stellantis, General Motors, and Tesla.
Our IATF 16949:2016 certified facility in Nogales, Mexico delivers the cost structure of nearshore manufacturing with the quality systems and engineering support your programs demand. Our in-house customs team manages USMCA compliance and tariff elimination, reducing total landed cost for components shipped to North American assembly plants.
Assemblies and Components
We manufacture complete mechanical and electromechanical assemblies using multiple integrated processes — supplied as tested, installation-ready components.
- Seating systems Seat adjustment components, reclining hardware, lumbar support systems, and power seat actuator components — built to meet cycle life, load, and NVH requirements across passenger car, truck, and EV platforms.
- Interior mechanisms Assemblies for power windows, door systems, console mechanisms, and cabin adjustment features — including wire harnesses, electric motors, and integrated electromechanical sub-assemblies.
- Manufacturing processes Our in-house capabilities include metal stamping, welded assemblies, staked assemblies, wire harness fabrication, and electric motor integration — allowing us to consolidate multi-process assemblies under one roof and ship finished, tested parts directly to your line.
Engineering Support
We offer full engineering services from concept through production launch. Under a black box design model, your team defines the performance requirements — load, travel, cycle life, packaging envelope — and we own the design, validation, and manufacturing solution. This keeps your engineers focused on vehicle-level integration rather than component development.
Our team supports prototype builds, design validation testing, and engineering updates aligned to automotive development gate schedules.
Why Automotive Customers Choose C.A. Spalding?
- IATF 16949:2016 certified Documented process control across incoming inspection, in-process checks, final testing, and corrective action — meeting the quality management requirements of OEM and Tier 1 supply chains.
- Nearshore cost advantage with tariff elimination Our Nogales, Mexico facility provides the labor cost structure of offshore manufacturing with the supply chain reliability of North American sourcing. USMCA qualification eliminates tariff exposure on components shipped to U.S. assembly plants — a significant landed cost advantage over Asian-sourced alternatives.
- Assembly consolidation We combine stamping, welding, harness fabrication, and final assembly under one roof — reducing your supplier count, simplifying incoming inspection, and cutting handling costs across your supply chain.
- 50+ years of automotive experience We’ve supported vehicle programs across seating systems and interior applications for passenger cars, trucks, and electric vehicles — with the production discipline and quality history that Tier 1 supply chain qualification requires.
