The main characteristics of the roll forming machine (1) Roll forming machine with grinding system allows grinding equipment production capacity into a full play, and generally improves the yield of 30% -40% and the total energy consumption can be reduced by 20% - 30%. (2) It has a compact structure, lightweight and small size. For the same production capacity requirements of the grinding system, the roll forming machine can save investment. (3) It has a simple structure, small footprint and more convenient operation and maintenance. (4) To compare the roll forming machine to other grinding equipment, the roll forming machine has less dust and low noise. Moreover, the work environment has greatly improved. Roll forming bending machines: The roll forming hydraulic bending machines has the characteristics of easy operation, maintenance, mechanical debugging and mold replacement. (5) The roll forming bending machine adopts a high level of automatic control software and easy to realize production information management. (6) The entire plant automation and control systems use the highly integrated networks, which have a better performance of automation systems, especially the color steels bending machine manufacture. The high-pressure roll forming machine: This roll forming machine production line has included a variety of walls forming machine, roof plate forming machine , forming machine and lining.
