PRIDE
our strengths
We accept maintenance requests throughout the year.
We value relationships that start from repair work.
We not only accept maintenance requests 362 days a year, but also have established a system that enables prompt on-site visits.
Maintenance 01
We provide maintenance for repairs and malfunctions 362 days a year (excluding New Year holidays). For our overseas locations, support begins on January 2nd, with a system in place to dispatch specialized maintenance personnel to the site from various global network.
Maintenance 02
We are committed to responding to all emergency repair requests. After assessing the situation and conditions, we make the necessary preparations and first visit the site to evaluate the situation, dispatching appropriate personnel anywhere in Japan and overseas.
Maintenance 03
We build equipment together with our customers. Therefore, any malfunctions or repairs that occur during actual use provide valuable data. While we promptly address repairs, we also feed these insights back into new projects and product development. This continuous cycle of improvement enables TOYO-RO products to evolve constantly, allowing us to deliver higher-quality products to our customers.
The group of newly developed products, which started with the development of gas furnaces in 1980, has been evolving year by year.
Our offices have been expanding overseas from 2012, and are moving towards the next generation.
Since its founding, TOYO-RO has been involved with continuous furnaces for over half a century. It represents continuous technological development and accumulated expertise.
History 01
In 1980, we successfully transitioned our heat source from electricity to gas, achieving dramatic reductions in heat treatment costs. In 1985, we developed the TXG (a direct furnace connection type atmosphere gas generator) to pursue further energy savings. These efforts remain the cornerstone of TOYO-RO’s energy efficiency and space-saving developments today.
History 02
The 1990s saw the development of key products that continue to support TOYO-RO today, including Black Furnaces (1986), Constant Parts Feeding Systems (1992), Development of Smoke Prevention Unit (1994), and Automated P/C Systems (1998). During this period, we focused on developing higher-quality products based on customer needs. This progress is the result of our commitment to valuing customer feedback and pursuing excellence.
History 03
Following our steady overseas track record, we expanded our business locations globally. In 2012, we opened a representative office in Thailand, followed by the establishment of TOYO-RO AMERICAN., INC. in Indiana, USA, in 2013. We established our local subsidiary TOYO-RO (Thailand) CO., LTD. in 2015. In the same year, we formed a business alliance with PT. MURASE INDONESIA to expand our services in the ASEAN region.
History 04
As environmental awareness grew globally, we focused on the effective utilization of waste energy, such as combustion exhaust heat, and developed a next-generation high-efficiency mesh belt type continuous furnace. We delivered the first unit in 2016. In 2018, we received the Energy Conservation Grand Prize for achieving 30% energy savings in continuous heat treatment furnaces through the introduction of new technology and multifaceted waste heat utilization.
History 05
Since our founding, TOYO-RO has been dedicated to continuous furnaces for half a century. The products we create today are made possible by the support of all our customers and partner companies. Moving forward, we remain committed to responding to our customers’ needs and contributing to society by leveraging TOYO-RO’s unique creativity—driven by the voices of our clients—to develop one-of-a-kind products.
TOYO-RO has established a comprehensive production system for planning, design, manufacture, installation and maintenance.
The products we produce are not standardized industrial furnaces.
We can closely and flexibly meet customers’ needs in all processes such as design, improvement and machine selection.
Integrated Production
step 01
The sales department receives orders and the design department creates drawings and proposals. By repeating preliminary discussions and meetings, we do not simply produce standardized industrial furnaces but also meet customers’ needs closely and flexibly in all processes such as changes and improvements at the design stage as well as the selection of each part and machine. To this end, we have been making an effort to reduce the number of repairs and problems on site by creating highly accurate drawings.
Integrated Production
step 02
We purchase parts from reliable associated companies and proceed to the manufacturing and assembly process. All parts used in assembly are fully traceable and managed in a digital system. In the assembly process, we leverage TOYO-RO’s decades of accumulated expertise in manufacturing. To ensure full traceability, we have implemented various inspection sheets.
Integrated Production
step 03
All employees, for all customers. All administrative staff at each location share a common understanding, and we are building systems to enable effective information sharing.
Integrated Production
step 04
Products are delivered and inspected after a final specification check, but TOYO-RO places importance on our maintenance system. For any repairs or requests arising after operation begins, we maintain individual equipment records for each unit, including maintenance and repair history.
