We have ultra-high temperature heat treatment furnaces! We will address your challenges with our years of heat treatment technology. Leave the coating and brazing of metals and ceramics to us!

We would like to introduce some coating examples. This one is tungsten coated with alumina (Al2O3). To enhance thermal efficiency, we have further coated the alumina coating with (alumina + tungsten). This is a component inside the cathode used in electric propulsion systems for small satellites, but it seems to be used in other applications as well. Our company has a well-equipped heat treatment furnace, and in addition to coating, we respond to various requests such as brazing and material development. We also accept commissioned processing from research and development, so if you have any concerns, please feel free to consult us first. ◆ We will propose solutions utilizing our heat treatment furnace tailored to your needs: - Coating - Brazing - Functional material development - Sintering - Residual stress removal - Crystal grain size control - Oxide removal - Contamination removal - Degassing - De-greasing ...and more.
