Coaken Techno Co., Ltd.

Coaken Techno Co., Ltd. (コーケン・テクノ株式会社) is a Japanese engineering manufacturer specialising in thermal spray (溶射, yōsha) systems. Based in Nishi-ku, Sakai, Osaka, the company describes itself as a comprehensive thermal spray equipment development and engineering maker that develops, manufactures and sells a wide range of thermal spray machines under its own brand. Thermal spray is a surface-treatment technology in which metals, alloys, ceramics or cemented carbides are melted and sprayed onto a workpiece to form a coating that imparts functions such as corrosion resistance, wear resistance, heat resistance, decoration, electrical conductivity and insulation. The company was established on 30 January 1973 (Showa 48) and is headquartered at 5-2 Tsukikohama-deranishi-machi, Nishi-ku, Sakai, Osaka, where its head office and factory are located. Its stated business scope covers the manufacture and sale of various thermal spray machines, the design, fabrication and sale of dedicated automated thermal spray systems, the sale of thermal spray accessories, ancillary equipment and thermal spray materials, and it also holds a construction business licence (machine and equipment installation work) from the Osaka Prefectural Governor. Its representative director is Koichi Akimoto, and its main banking relationships are with the Sakai branches of Sumitomo Mitsui Banking Corporation and Awa Bank. Coaken Techno's product range spans gas-flame spray machines (wire and powder types), arc spray systems, plasma spray systems, ceramic rod spray machines, HVOF and hybrid HVOF systems, and HVAF systems, together with a broad line of accessories such as control panels, gas flow meters, air control units, gas regulators, hose sets, wire straighteners and extension nozzles. The company positions itself as offering a one-stop solution that extends beyond the spray process itself to robotics and conveying equipment, so that each customer's production line can be optimised for efficiency, economy, SDGs and work-style considerations. Its arc spray machines in particular are widely adopted as production spray equipment for automotive parts, electrical components and steel products, and have been exported in large numbers to Southeast Asia and the United States. Coaken Techno has a global footprint: its machines are used in China, South Korea, Southeast Asia, the Middle East, Europe and North America, it has sales agents in four countries, and it also serves as the Japanese sales agent for an Indian thermal spray machine manufacturer. The company has marked its 50th anniversary since founding and states that it follows the management philosophy of "商いは牛の涎" (business is like a cow's saliva — steady and continuous). It has been recognised as one of the KANSAI Monozukuri Genki Companies 100, an Osaka Genki Monozukuri Company, one of the Sakai Excellent Companies 100, and a Sakai Environmental Challenge Company.
