In the old days, the metal sheets shaped by machines called "manuel sheet metal brake", which are man-powered machines, became thicker and more complex with evolving industrial needs, therefore new technologies were developed because thick sheets could not be bent with manpower, and press brake cutting and bending are among those technologies that arise in parallel to this need. The metal sheet is cut in the sheet cutter machine (guillotine) according to the desired size and is bent to the desired form in the bending machine. Press brake bending machines are generally simple and functional machines consisting of CNC control unit, hydraulic axes, and lower and upper mold (female and male mold) units, and are produced in different tonnages depending on the twisting power. The pressure is applied by the male mold towards the female mold and thus the metal sheet is bent to the specified degree. The molds have a classic V shape. In press brake bending machines, various twisting designs can be instantaneously applied and archived for future use in the design control unit.
As CFS Profile, though we prefer production with roll-form technique by making the necessary mold investments at times when many profiles need to be produced constantly as profiles; however, when a small number of profiles are needed, when the cost of mold investment does not set off the production cost, and when the need for the transverse cross-section of new profiles/products that would not fit into roll form machines arises, we prefer press brake bending.
