Roll forming is a continuous bending operation in which a strip of metal, typically twisted steel or aluminum, passes through successive sets of rollers or stands. Each of the rollers only performs an incremental part of the bending to obtain the desired cross-sectional profile.

As well as being reliable, 4 rollers bending machine increases productivity with its high speed rolling ability and it overcomes the most challenging bends thanks to its ease of use. Since the plate is pinched during rolling, skidding and slipping of materials are prevented. Thus, more.

Fiber lasers have several main advantages. One is that in emitting their light, the environment is well protected and these lasers are designed very compactly. They have a large gain bandwidth, tuning range for wide wavelength and
