TMI

What TMI does

TMI, Inc. (d/b/a Team TMI) is a privately held, family-owned custom manufacturer of molded rubber parts founded in 1984 by Michael J. Myhal Sr. and headquartered in a 30,000 sq ft facility at 6475 Victoria East Road, Youngstown, Ohio. The company produces custom rubber components using compression, transfer, injection, and extrusion molding, supplemented by die-cutting, rubber-to-substrate bonding (to metal, plastic, and fabric), prototyping with CAD/CAM and 3D printing, in-house mold making and CNC machining, and certified clean room assembly (Class 100 to Class 100K). It processes an elastomer portfolio spanning Nitrile, EPDM, Viton, Fluorosilicone, Neoprene, Butyl, Silicone, SBR, Hydrin, and Hypalon, and supports customers with packaging, labeling, and finishing in-house. Recent capital investments include a Pan Stone 350-ton vacuum press (May 2023) and a Dynapath CNC lathe (June 2023).

TMI holds ISO 9001 certification and qualifies AMS and Mil Spec materials for aerospace and defense applications, along with FDA-compliant silicone for food and medical use. Testing is performed in-house and through partnerships with Akron Rubber Development Labs and Smithers Scientific Services. The company serves twelve vertical markets, with aerospace and military described as primary, alongside automotive, electronics, medical, transportation, marine, oil & gas, agriculture, appliance, food, and consumer goods. Notable historical projects include seals for landing gear on the space shuttle and parts for defense systems.

TMI's commercial model is project-based custom manufacturing with quote-driven pricing and direct enterprise sales through a website RFQ form and phone-based engagement, supported by content marketing (blog, social channels) and PR (Voyage Ohio Magazine). Revenue is generated from one-time contracts spanning short runs (as few as 20 parts) to high-volume production, with the President personally involved in key customer relationships. The company has remained under Myhal family ownership across its 35+ year history, with several original 1984 employees still on staff, indicating organizational continuity rather than rapid scale.
