Montville Plastics & Rubber

What Montville Plastics & Rubber does

Montville Plastics & Rubber is a privately held, family-owned custom plastics manufacturer founded in 1977 and headquartered in Parkman, Ohio. The company operates 100,000-150,000 square feet of manufacturing space, employs 50+ people across two divisions (Montville Plastics & Rubber and the wholly-owned Iron Horse Engineering rail division), and runs 20 single and twin extruders plus an injection molding division with machines up to 90 ounces and 730 tons of clamping force. Its in-house capabilities span the full product lifecycle: design and engineering (including CAD modeling and 3D printing for rapid prototyping), tool and mold making (three wire EDM machines, a CNC machining center, and a library of more than 5,000 dies built over 40 years), plastic extrusion up to 48 inches wide with dual and tri extrusion co-extrusion, injection molding with over molding and insert molding, and value-added services such as assembly, drilling, welding, printing, and custom packaging. Materials expertise covers 30+ thermoplastic compounds including ABS, rigid and flexible PVC, HDPE/LDPE/PET, polypropylene, polyurethane, Santoprene TPV, and TPE.

The company sells exclusively on a B2B direct sales basis under a quote-based, project-specific pricing model, positioning itself as an extension of the customer's product development team rather than a transactional vendor. It serves six named vertical markets — Trailer & Automotive, Rail/Freight & Transit, Construction & Industrial, Electrical & Lighting, Agriculture & Farming, and Consumer Products — with products ranging from trailer door seals and HDPE scuff liner boards to rail boots, tie pads, elastomeric grout, electrical innerduct and bus bar insulation, agricultural seals, and consumer items sold through Home Depot, Lowe's, and Amazon. The rail franchise, acquired via Iron Horse Engineering in 2002, supplies products used across more than 1 million miles of track for transit and heavy haul freight lines.

Revenue is generated primarily through one-time production orders tied to custom tooling and ongoing part production, supplemented by tool and mold development projects and value-added service fees. Marketing is conducted through the company website with a quote request flow, trade show participation (Design-2-Part, Building & Construction Showcase), active blog content, organic social media on Facebook/Twitter/LinkedIn, and memberships in MAGNET and REMSA. There is no public pricing, no disclosed revenue, no external funding, and no AI/ML or software product surface.
