Top Manufacturing Companies in Ohio: The Heart of American Industry
Ohio has long been known as the industrial heartland of the United States. Historically rooted in steel and rubber, the state’s manufacturing sector has evolved into a high-tech powerhouse. Today, Ohio ranks among the top states for manufacturing GDP, driven by strengths in automotive, aerospace, and—increasingly—semiconductors.
Here are the top manufacturing companies leading the industry in Ohio:
1. Honda Heritage (Automotive)
Honda is perhaps the most iconic manufacturer in Ohio. Its massive Marysville Auto Plant was the first Japanese auto plant in the U.S. Today, Honda operates multiple facilities across the state (including Anna and East Liberty), producing millions of vehicles and engines. Honda is also partnering with LG Energy Solution to build a massive $4.4 billion EV battery plant in Jeffersonville, securing Ohio’s future in the electric vehicle era.
2. Intel Corporation (Semiconductors)
In one of the largest economic development projects in U.S. history, Intel is currently building a "mega-site" in Licking County (near Columbus). This $20 billion investment aims to create the largest semiconductor manufacturing location in the world. This project is expected to transform Ohio into "Silicon Heartland," attracting an entire ecosystem of high-tech suppliers.
3. GE Aerospace (Aviation)
Headquartered in Evendale (near Cincinnati), GE Aerospace is a global leader in jet engine manufacturing. They design and build engines for both commercial and military aircraft. Ohio is the primary hub for their research, development, and advanced manufacturing, supporting a massive network of specialized aerospace suppliers throughout the state.
4. The Procter & Gamble Company (P&G) (Consumer Goods)
While P&G is a global giant headquartered in Cincinnati, it maintains significant manufacturing operations across Ohio. From specialized chemicals to household brands like Tide and Crest, P&G’s advanced manufacturing processes in Ohio set the global standard for the consumer packaged goods industry.
5. Goodyear Tire & Rubber Company (Chemicals & Rubber)
Based in Akron, the former "Rubber Capital of the World," Goodyear remains a vital part of Ohio’s industrial identity. While much of their bulk manufacturing has globalized, Ohio remains the center for their high-performance tire manufacturing, research, and specialized polymer production.
6. Parker Hannifin (Industrial Systems)
Headquartered in Cleveland, Parker Hannifin is a global leader in motion and control technologies. They manufacture highly engineered components for aerospace, climate control, and electromechanical applications. Their precision manufacturing facilities are spread across Ohio, providing essential parts for almost every machine that moves.
7. Sherwin-Williams (Coatings & Chemicals)
Another Cleveland giant, Sherwin-Williams is one of the world's largest manufacturers of paints and coatings. With a history spanning over 150 years in Ohio, they operate advanced chemical manufacturing plants that supply both the construction and industrial sectors globally.
Key Strengths of Ohio Manufacturing
Logistical Advantage: Within a one-day drive of 60% of the U.S. and Canadian populations, Ohio is a prime location for distributing manufactured goods.
The "Silicon Heartland" Shift: The arrival of Intel is shifting the state's industrial focus from traditional "Rust Belt" manufacturing to "Brain Belt" high-tech fabrication.
Manufacturing Workforce: Ohio boasts one of the most skilled and concentrated manufacturing workforces in the country, supported by specialized technical colleges.
