DOWA THT America, Inc. (DOWA THT) was established in 1997 and began operations in 1998 in Bowling Green, Ohio, as a subsidiary of Japan’s DOWA Thermotech Co., Ltd. The company was founded with the goal of meeting the North American demand for advanced heat treatment, initially targeting the automotive industry and expanding over time to serve the construction, agriculture, and green energy sectors.
DOWA THT operates two independent divisions. One division is the Commercial Heat Treatment Division, which is operated locally and has been expanded four times since the original building was constructed. This facility is equipped with 24 batch furnaces, four tempering furnaces, six vacuum wash machines, and two continuous furnaces, most of which are DOWA THT brand equipment.
The second division is the Furnace Equipment Division, which is responsible for the design, manufacturing, installation, and maintenance of all equipment sold domestically. The overwhelming majority of equipment sold at the Commercial Heat Treatment facility and the parts processed there are for the automotive industry, but the facility also caters to other fields, such as construction, agriculture, environmentally friendly energy production, and advanced industries. The Furnace Equipment Division provides a full range of services, including sales, installation, commissioning, preventive maintenance, and emergency maintenance, from Canada all the way to Brazil.
The Commercial Heat Treatment Division processes parts onsite at the Bowling Green facility to enhance material properties for durability and performance. Examples of the parts processed are gears, shafts, transmission parts as well as agricultural machinery parts. The company’s services in this field focus on carburizing, carbonitriding, nitriding, ferritic nitrocarburizing, quench and temper, and hardening. They are also considering adding annealing as part of its capabilities.
The Bowling Green facility uses a patented QSQ quenching process developed to reduce distortion. With this patented process, DOWA THT has significantly reduced post-process work steps for its customers for many years.
A key feature of the Bowling Green facility is that the Commercial Heat Treatment Division and the Furnace Equipment Division operate within the same facility. This structure allows potential customers to visit the operational furnaces prior to purchase and observe the visual flow of the heat treatment process.
The biggest advantage of the Furnace Equipment Division is its turnkey operation. From design to manufacturing, DOWA THT manufactures all equipment and can handle all processes, including transportation, customs, and installation.
DOWA THT is a company that demonstrates leadership across a wide range of industries and is trying to continue to develop new technologies every year. They are capable of designing equipment tailored to customers’ specific specifications, including safety features to protect their employees.
In addition to its U.S. base, DOWA THT has a heat treatment facility in San Luis Potosi, Mexico. The Mexican facility began operations in 2015 and continues to expand. If a customer chooses to manufacture in the U.S. or in Mexico, their North American bases work together to meet all customer needs in both countries.
Whether it’s providing turnkey services in Ohio or designing and installing a custom furnace in North and South America, DOWA THT utilizes their technical expertise housed in their dedicated staff to fuel their dual division model. They are zeroing in on innovating heat treatment solutions and technologies for the future, while investing in sustainable practices to lessen their environmental footprint. With a focus on targeting new growth areas, such as renewable energy, automation, and advanced manufacturing, they are executing on a multi-year plan to integrate real-time monitoring and AI-generated predictive maintenance to enhance overall client experience.
