This time we have received a courtesy visit from the Sumiyoshi Tax Office as an excellent tax return corporation.
An excellent tax return corporation means ' a corporation that continues to file and pay taxes properly with the purpose of the tax return system and is recognized as a model for other taxpayers.'
It was a great honor for us to receive the second courtesy visit following 2013. We would like to continue to be a company that can contribute to our customers and society.

For the first time, we have established a good friction welding technology for Chromium copper (C18200) and Pure titanium type 2.
Pure copper (C1020) and Pure titanium type 2 have been applied with good friction welding technology so far, but Chromium copper has stronger strength than Pure copper, so it could not be bonded under similar conditions.
As a result of trial and error, it was confirmed that the Chromium copper side bends without breaking the joint in the bending test centered on the joint as shown in the photograph.
