Production of complex shapes with the use of unique and improved drawing bench machines

●Molding method in line with product features
There are two types of cold roll forming: drawing bench (roll drawing-type) and forming machine (roll extrusion-type). Molding methods are decided based on the lot, shape, and plate thickness to make the most of the features of the molded product.

●Original deformation processing technology
Unique deformation processing (folding) technologies are applied mainly to stainless steel materials to manufacture die steels in various shapes. O.F. currently has over 1,000 types of die steels that can currently be produced.

● Original equipment
O.F. has three remolded and dedicated drawing benches in-house that can support the manufacturing of impossible shapes in press working and bending and molding long-length objects up to 12 meters, with sharp corners. In addition, defects in twisting, warping and bending can be reduced to within 1 mm for every 1 meter with high precision.

●Mechanism
- Set the upper, lower, left and right mold rolls (upper/lower free) on the assembled table-style stand
- Pick up the tip of the material using the catcher from the uncoiler

● Manufacturing process
(1) Mold along the roll while it is drawing
(2) Stop the catcher at predetermined positional dimensions and cut
(3) Reposition the catcher position and repeat the molding process

●Mechanism
- Shafts for upper and lower mold rolls at each step
- Upper roll is free. Lower roll is driven by the motor with the same rotation in each stage.
- Automatic continuous molding is possible

● Manufacturing process
(1) Mold along the roll as material is fed from the uncoiler
(2) Interlock machine and NC and cut at prescribed positional dimensions
