Die-less forming, a new sheet-metal forming method, creates required shapes easily using 3D Data, instead of the stamping method or skilled technique.
We challenged/achieved the new technology to complete parts of wing partitions
The basic idea of Die-less forming, or Incremental NC forming
A forming method for the work, processed material, fixed on the X-Y axis table with pressing the ball-shaped mobile tool fitted at the top of Z axis using contour line data.
* The method was developed and patented by a Prof. of Polytechnic University
Only the head part of work is fixed. The other part is formed in the air with data.
- Supply formed sheet metal parts with higher quality and lower cost instead of
existing handmade method.
- Supply formed parts, difficult with existing handmade method, easily.
- Mechanization makes technology transfer, previously difficult, easier.
Successful example products
|Wing partition for railway cars
General description of development
Wing partitions at both sides of long benches of railway cars, developed with new technology. They have recycle-friendliness, lighter weight, lower cost and shorter lead time. They are achieved with a synergy effect of each element technology.
