Honda Motor Co., Ltd.
Saitama Factory Yorii Automobile Plant

Within Honda Motor Co., Ltd., Saitama Factory’s Yorii Automobile Plant functions as a sort of mother factory for cutting-edge production technology. As part of its safety efforts, the plant has introduced a control system for furnaces that is compliant with JIS B 8415, the latest Japanese industrial combustion safety standard. The system is used on automobile production lines for paint booth air conditioning, paint drying, and deodorization facilities. In addition, the plant is preparing to distribute this know-how to Honda’s production bases around the world.

With safe combustion control compliant with the latest JIS regulations, Honda aims to achieve safe operation by adopting cutting-edge technology

Holding out the ideal of developing useful technologies to help people, Honda Motor Co., Ltd., since its founding in 1948, strives to develop technology and products that bring happiness to customers around the world. In recent years, with its HondaJet, Honda has established itself as a manufacturer of aircraft for business, in addition to its main business areas, namely automobiles and motorcycles. In this way, the company continues to challenge itself, using its global slogan, “The Power of Dreams,” as an engine to propel itself forward.

Honda’s Saitama Factory, which consists of Sayama Automobile Plant, Yorii Automobile Plant, and Ogawa Plant, accomplishes the entire process of automobile production, from pressing of the auto body parts to welding, painting, and assembly, and serves as a manufacturing point for Honda’s other 68 production bases located in 27 countries (including Japan). The Yorii facility in particular, which has been in operation since July 2013, stands out as one of the largest production sites in Japan, producing 250,000 cars annually. Honda employs all sorts of advanced technology in this plant in order to reduce environmental impact by minimizing CO2 emissions from the manufacturing process, and also to improve product quality. Honda expects the factory to be a “mother factory” that shares her knowledge with overseas production bases.

“For the Yorii Automobile Plant, adoption of the most advanced technology was a requirement already in the plant construction plan, not only for the environment and for quality, but also for safety, which is the most important thing on the production line. Particularly for automobile production lines, the air conditioning of paint booths, where strict control of temperature and humidity is required, and the safe control of gas burner combustion, which is a very important function in the drying stage after painting and the exhaust deodorization stage, were the main concerns,” says Yuji Ito, an engineer in the Production Supervisory Unit.

“Our company has had and operated strict internal regulations, namely explosion and fire safety standards, for processes in which fire is used. In recent years public standards have also been reviewed or established, and since JIS B 8415,*1 related to the safety of combustion equipment, was revised, we thought that, if we aim to be on the cutting edge of operational safety, we should comply with the revised JIS regulations,” says Yoshiyasu Kogo, the chief engineer of the Yorii Management Department.
