Introduction to Principal Businesses
Heat treatment business
There is demand from the metals parts for increasingly advanced and sophisticated heat treatments to make metal materials stronger and more durable.
Dowa Thermotech boasts Japan’s largest heat treatment organization, with nine plants across the country, and offers the highest quality and best service.
This high quality and excellent service is backed by about 20 surface treatment processes.
The company offers the optimum process to meet diverse needs and applications, including carburizing to increase the abrasion resistance of metal surfaces, a proprietary gas nitrocarburizing toughnite process to heighten fatigue resistance, the TD process to increase the fatigue resistance of molds, and the Corbett process for improving seizure resistance.
Industrial furnace business
Dowa Thermotech’s industrial furnace business is growing in tandem with the automobile industry.
Engine and transmission parts are used under severe conditions. High reliability and advanced technology are needed in parts that bear directly on automotive safety. The technological expertise and trust the company has earned are most important in responding to these requirements.
In the industrial furnace business, the company employs its practical experience in heat treatment to offer complete services ranging from facilities design to startup and maintenance.
The company has the strongest domestic track record in the field of carburizing heat treatment facilities, where demand is particularly strong.
At present, Dowa Thermotech is also emphasizing the development of new technology. It has developed and delivered a small continuous type furnace (S-TKM) with three times the productivity of earlier batch type furnaces in the same space, and a continuous type furnace that meets customer needs for high quality.
Dowa Thermotech has recently launched a number of new products, including a continuous type nitriding furnace for continuously variable transmission (CVT) parts, where demand is expanding, and a series of new-type carburizing furnaces that offers a reduced environmental impact and energy conservation.
