Molded Fiber Glass (MFG) Companies

What Molded Fiber Glass (MFG) Companies does

Molded Fiber Glass (MFG) Companies is a privately held, family-owned custom molder of fiber reinforced plastic (FRP) composites headquartered in Ashtabula, Ohio, founded in 1948 by Robert S. Morrison. The company operates 14 manufacturing facilities across North America (eight US states plus three plants in Mexico) with approximately 2,500 employees, producing custom composite components for OEM customers in automotive, heavy trucks, wind energy, defense, construction, HVAC, material handling, mass transit, and water management. MFG is the original manufacturer of the fiberglass body for the Chevrolet Corvette (since 1954) and supplies major OEMs including General Motors, PACCAR (Peterbilt), Yamaha, GE Energy, and American Seating.

MFG's technical capabilities span high-volume compression molding/SMC, liquid composite molding (LCM) including the proprietary MFG PRIME process, resin transfer molding (RTM), vacuum infusion, and open molding. The company distinguishes itself through proprietary material formulations—Float SMC (the first commercially available SMC with specific gravity less than water at 0.95), the iNVENTA family (UL-recognized non-halogenated fire-safety SMC), iCom SMC materials, and an in-house R&D operation (MFG Research) with a dedicated design center. Certifications include ISO 9001:2015, ISO 14001, UL 723, and UL 94-5V across applicable facilities and materials.

The business model is project-based custom manufacturing with quote-based pricing determined by part specifications, material requirements, and production volumes. Revenue is transactional (one-time purchase contracts) with multi-year program durations typical for OEM supply agreements. MFG sells through a direct field sales organization with technical sales engineers embedded in customer engineering and procurement processes, supported by 14 strategically located facilities enabling JIT delivery. The company is family-controlled across four generations of the Morrison family, with no external institutional investors and no public funding rounds.
