processing technology
Variable thickness precision forging press and welding
overview
The frame used to be fabricated with
cold forging and cut process.
However, with our patent method,
stamping is adopted to the entire
process, and it allows remarkable
cost reduction. Stamping enables to
flexibly thinned down and thicken the
material from 25% to 192%.
The entire processes from stamping
to welding are consistently handled
by our company.
