Roll Forming Machine Technology Development

         The first roll molding machine appeared around 1900, and the application of its technology developed slowly in the first 50 years of the 20th century.After The Second World War, with the increase in the demand for metal forming products, cold bending forming technology gradually became popular.Due to the increase of labor cost and the improvement of efficiency of cold bending production line, more and more metal bending products adopt cold bending forming technology.Although the basic structure of the cold bending machine is not very different from the earlier machine, but there are new improvements to increase the production of cold bending forming, improve labor productivity.
