What Summit Polymers does

Summit Polymers, Inc. is a privately held automotive interior systems supplier founded in 1972 by Jim Haas and headquartered in Portage, Michigan. The company designs, engineers, and manufactures injection-molded polymer interior components and full assemblies — including consoles, instrument panel and console trim, door panels, air vents, cup holders, center finish panels, and kinematics — for major automotive OEMs. Its manufacturing platform spans 12-14 global facilities across the United States, Mexico, and China, supported by design centers in Michigan and Nanjing that provide 24-hour engineering coverage. The company employs 280+ injection molding machines with automation and operates under a Toyota Production System / lean manufacturing model delivering just-in-time to customer assembly plants.

Summit's technical differentiation centers on its Knowledge Based Product Development (KBPD) methodology — a proprietary process drawing on an expanding library of case studies, standards, and lessons learned — combined with an extensive decorating technology portfolio covering paint and pad printing, applique films, ambient and accent lighting, leather/vinyl wrapping, laser etching, piano black PMMA molding, and multi-shot molding. The company holds IATF 16949 and QS-9000 quality certifications and is certified as both a Women's Business Enterprise (WBENC) and a Veteran-owned Business (NVBDC). It is led by Andrea Haas as President, with John Meyer as VP/CFO and Art Mixis as Chief Engineer.

Revenue is generated through long-term direct supply contracts with major automotive OEMs — General Motors, Ford, Fiat Chrysler Automobiles (Stellantis), Toyota, Volkswagen, and Lincoln — under a just-in-time delivery model with EDI-based order management (DELFOR, DELJIT, DESADV). The go-to-market motion is enterprise field sales, with global platform programs supported by full-service engineering from concept to launch. The company has been recognized as GM Supplier of the Year for ten consecutive years (2014-2017, 2019-2025), a Ford World Excellence Award recipient, and an FCA Supplier of the Year, reflecting entrenched positions within incumbent OEM platforms.
