Macoho Co., Ltd.

Macoho Co., Ltd. is a Japanese company that specializes in the development, manufacture, and sale of wet blasting equipment. Wet blasting, also known as wet-style blasting or liquid honing, is a surface treatment technology that mixes abrasives with a liquid (mainly water) to create a slurry that is sprayed onto workpieces using compressed air. The company was founded in May 1983 as a design contractor and has since grown into a specialized manufacturer of custom-made wet blasting machines. Over its history, Macoho has manufactured more than 2,000 units of wet blasting equipment, ranging from tabletop-sized machines to large industrial systems. These machines are installed in companies worldwide, primarily serving the automotive, cutting tool, and semiconductor industries. Macoho's product lineup includes manually operated, semi-automatic, and fully automatic wet blasting equipment, as well as custom-designed systems tailored to specific customer needs. The company also supplies consumables such as abrasives and provides inspection, construction, and after-sales services. Key applications of its technology include surface treatment of electronic parts like PCBs and semiconductors, improving coating strength and cutting edge life for carbide tools, and removing black scale and providing lubrication for cold forging dies through its proprietary WLS technology. Headquartered in Nagaoka City, Niigata, Japan, Macoho operates internationally with subsidiaries and offices in the United States and China. Macoho America, Inc. is located in Plain City, Ohio, and the company has a representative office and a machinery technology company in Shanghai, China. As of its corporate profile, Macoho has 139 employees and a capital of 45 million yen. The company is led by Representative Director Yoshihisa Asai. Macoho continues to exhibit at industry events such as Manufacturing Technology series SOUTHWEST, SMTA International, and DesignCon, demonstrating its ongoing engagement with the electronics manufacturing and technology sectors.

Macoho Co., Ltd. was founded in May 1983 in Japan, initially operating as a design contractor. From its early days, the company focused on manufacturing custom-made equipment, which laid the foundation for its specialization in wet blasting technology. Over the decades, Macoho developed proprietary know-how in wet blasting—a process that mixes abrasives with water to create a slurry sprayed onto surfaces for cleaning, finishing, and surface preparation. This technology proved particularly valuable for high-precision applications where conventional methods like shot blasting or pickling were less effective or environmentally problematic. By continuously refining its technology, Macoho grew into a specialized manufacturer of wet blasting equipment. The company has manufactured over 2,000 units of wet blasting machines, ranging from compact tabletop models to large industrial systems. These machines have been installed in companies worldwide, serving industries such as automotive, cutting tools, and semiconductors. Macoho's equipment is used for applications including surface treatment of electronic parts like PCBs and semiconductors, improving coating strength and cutting edge life for carbide tools, and removing black scale and providing lubrication for cold forging dies through its proprietary WLS technology. To support its international customer base, Macoho established overseas operations. Macoho America, Inc. was set up in Plain City, Ohio, USA, to serve the North American market. In China, the company operates a Shanghai Representative Office and Shanghai Macoho Machinery Technology Co., Ltd., located in the Lin-gang Special Area of Pudong New Area, Shanghai. These offices provide sales, service, and technical support to customers in the region. As of its corporate profile, Macoho has 139 employees and a capital of 45 million yen. The company is led by Representative Director Yoshihisa Asai. Macoho remains active in industry events, exhibiting at trade shows such as Manufacturing Technology series SOUTHWEST, SMTA International, and DesignCon, reflecting its ongoing commitment to the electronics manufacturing and technology sectors. The company continues to innovate in wet blasting technology, promoting its solutions for clean, high-precision oxide scale removal that can replace traditional shot blasting and pickling processes.
