Miyakawa Kougyou Co., Ltd.
Joining dissimilar metals with our continuous-furnace one-stop brazing technology
Our main business is metal stamping, and we also produce mufflers for outdoor air-conditioning units and turbocharger actuators. After developing the technology for continuous-furnace one-stop brazing, we worked on joining not only similar metals like iron and iron but also dissimilar metals like iron and copper. We can apply one-stop brazing to all products, making complete automation possible. We have also introduced a helium leakage testing method that allows us to improve the defect rate and revise the inspection process. By systemizing the one-stop brazing process and highly accurate leakage test, we aim to achieve a zero defect rate while maintaining outstanding product quality.
[Company strength] Brazing is a widely used metal-joining process in which an alloy is melted and used as an adhesive filler to join two or more metal pieces, generally similar metals (iron and iron). Our company can join not only similar metals but also dissimilar metals (iron and copper) in one operation. There are very few companies in Japan that offer continuous-furnace one-stop brazing. [Business description] Since its foundation in 1962, our company’s primary business field has been metal stamping at three sites: Fujieda, Shizuoka, and Chonburi Province in Thailand. We produce mufflers for outdoor air-conditioning units and actuators for turbochargers (added to automobile engines). By meeting the many needs of our customers, we have accumulated a wide range of technologies and expertise. [Industry] Metal product manufacturing industry [Strength of products/technologies] We developed a technology for continuous-furnace one-stop brazing, and our machinery can apply one-stop brazing to all products, making complete automation possible. This eliminates the pipe-welding process, shortens the delivery time, saves space, and reduces labor. We have also introduced a helium leakage testing method that allows us to improve the defect rate and revise the inspection process. This testing method uses helium, which is an excellent search gas because of its tiny molecular size that reveals even the smallest leaks. Therefore, this test is expected to prevent post-delivery defects. By systemizing our well-regarded one-stop brazing process and highly accurate helium leakage testing method, we aim to achieve a defect rate close to zero while maintaining outstanding product quality. [Representative's message] Seventy years have passed since our company started doing business as a metal stamping and brazing manufacturer. Even with the increasingly severe economic situation, we continue to do our utmost for our customers. We have constructed a system that combines continuous-furnace one-stop brazing, a technology that we spent years developing and that enables complete automation, with helium leakage testing, which detects joint leaks with high sensitivity and accuracy. With the establishment of a production site in Thailand, we are looking to further raise our product quality and production efficiency and generate new business opportunities overseas. [Company structure for market development/overseas expansion] We established Miyatech (Thailand), a local subsidiary in Thailand, fully financed by our company, and installed a continuous-furnace one-stop brazing system. Using as a springboard our business ties with the local Thai compressor subsidiary of Mitsubishi Electric Corp., our main customer, we are expanding globally, with an eye to overseas exports and opening up business opportunities with local Thai companies.
