A group of specialists in thermal spraying. We handle various processes from arc spraying to pre-treatment and finishing!
It is a type of electric spray coating that generates an arc discharge (electric spark) between two metal wires, using the discharge energy to melt the wires. The wires are fed in accordance with the melting rate, and compressed air is used to atomize the molten metal, which is then continuously sprayed onto the substrate to form a film. Compared to flame spraying methods, it has a higher spraying capacity (amount of coating per unit time) and excellent adhesion to the substrate due to the spraying material being sufficiently melted at high temperatures. The power supply for the arc spraying device can be alternating current, but direct current is used for stability of the arc. Since the wires act as electrodes, the spraying materials are limited to electrically conductive materials.

Company information
Since its founding, Niigata Metalicon Co., Ltd. has been on a path of technological development in the fields of metal rust prevention, corrosion resistance, and wear-resistant processing. Starting in 1950 as Minato Plating, a comprehensive metal surface treatment company, we ventured into the broader field of metal thermal spraying in 1953, aiming to establish a system that could meet extensive needs. At that time, metal thermal spraying was not yet widespread in the region, but our unique technological development proved successful, earning us praise from local users. In 1961, we reorganized and changed our name to Niigata Metalicon Co., Ltd. This marked the beginning of our efforts to improve our internal organization as a company, expand our facilities, and transform into a modern corporate entity. We have continuously engaged in proactive technology acquisition, keeping pace with the rapidly changing waves of technological innovation. We have also formed technical partnerships with leading companies such as Dow Corning and Kanizen in Japan, and we have ventured into new fields, including electroless nickel plating. Niigata Metalicon Co., Ltd. aims to advance with the social mission of providing advanced technology to the region.
