Thermal Spray Equipment Manufacturer in JapanCoaken Techno Co., Ltd.

Coaken Techno, as only one manufacturer of thermal spray equipment in Japan, has been devoting and servicing for the thermal spray fields in Japan also as well Korea, China, Thailand, Philippines, Indonesia, India and the U.S.A. for more than 50 years.


There are as many optimal solutions as the number of workpieces.

Surface modification and formation of functional coating

Thermal spraying is the process of melting materials such as metals, alloys, ceramics, and cermet and spraying them onto the workpiece to form a coating on the surface. This technology provides functions such as corrosion resistance, wear resistance, heat resistance, decorativeness, electrical conductivity, and electrical insulation.
Coaken Techno presents the optimal solution and the most effective system to maximize the desired effect.

Proposal of the perfect
application for the thermal
spraying process.

The thermal spraying process is infinitely different
for each production site.
The application will further improve the thermal spraying process
while considering versatility and the perspective of SDGs
and work styles, as well as efficiency and economic effects.
COAKEN TECHNO offers one-stop solutions for everything
from the construction of highly specialized thermal spray systems
to the ancillary systems such as robotics and workpiece transfer system.
