Compared to machining a round bar with a flange shaft, there is a record of reducing material costs by 55%. *Introduction of reduction case.
"Friction welding" is a welding method that generates friction heat as a heat source by applying pressure to metal contacts while causing relative motion. Our company recognized the advantages of this friction welding early on and has utilized it in our products, as well as widely accepting processing requests from everyone, contributing to cost reduction and quality improvement. Currently, we are equipped with five automatic friction pressure welding machines and are accepting contract processing. [Features] ■ The mechanical strength of the joints is extremely high ■ Does not require welding rods or solvents, and does not need special groove processing ■ High energy efficiency ■ Capable of joining dissimilar metals ■ Material savings and reduction of man-hours are possible *For more details, please refer to the catalog or feel free to contact us.
