HBD Industries Inc
HBD Industries traces its corporate roots to 1864, but the modern firm was incorporated in 1989 when the Evans family acquired businesses and assets from H.K. Porter Company. Thomas Mellon Evans, an early corporate raider, had already spent decades assembling industrial subsidiaries; HBD was the vehicle that consolidated and continued that legacy. The firm remains family owned with a professional board of directors. The firm's five business platforms — Rubber Products, Gearing Product Solutions, Electric Motors, Industrial Magnetics, and Precision Components — serve aerospace & defense, medical devices, material handling, food processing, power generation, and oil & gas markets. Current portfolio companies include Thermoid (industrial rubber products), Winsmith and Perfection Gear (gearing solutions), Powertec Motors and Ohio Electric Motors (custom electric motors), Ohio Magnetics (lifting magnets and separation equipment), Precision Metal Products (high-alloy forgings), and True Position Technologies (precision machined components). Past holdings include Hydro Carbide Tool, Madison Manufacturing, Carolina Rubber Rolls, California Drop Forge, and Peerless Electric — each held for decades before divestiture. HBD is headquartered in Dublin, Ohio with no separately disclosed AUM, professional headcount, or additional offices. The firm describes itself as an integrated operating company — distinct from a passive holding company or family office — that partners with management teams to grow engineered-product businesses. No recent operational event was publicly verifiable within the last 24 months. HBD's structural differentiator is its architecture: a family-controlled, professionally managed operating company rather than a traditional family office making passive investments. The firm directly owns and operates middle-market manufacturing businesses, actively managing day-to-day operations through a shared business system. This hands-on, permanent-capital structure is uncommon among family offices, which typically separate investment from operational control.
