Roll forming machine is very important, it is used for forming outer panel, which will influence the surface quality of sandwich panel. This is one core part of the whole production line, which is one of important steps for guaranteeing the high-quality sandwich panel.

The numbers of stations in roll forming machine is designed by adopting the German software COPRA in theory and then tested in practice. All the rollers after finish machining are coated by chrome which has a good adhesion by slow plating technology. The rollers are processed in numerical control machining centre in one step and grinded in the mirror grinder to improve the smooth finish. This kind of roller treatment can reduce the inner stress release and guarantee the flatness of panels during the forming period. The roll forming machine adopts the two-head type which have two sets of rollers in each side. One more profile will be formed by exchanging the former position.

Roller adopts high-grade steel with thorough heat treatment and accurate processing by CNC machine tool, surface coated with chrome to increase degree of finish and hardness, so that can increase the using life. Small corrugated roller is very important, if up and down roller caity is misfit, the height of small corrugated panel on the surface is not the same, which will cause the phenomenon of refraction no uniform or even destroy the surface quality of steel panel. The roller adopts integral structure, a process in the large CNC machine with high rigidity, high intensity and high accuracy. If want to increase roof panel forming machine(optional), can adopt integral type machine frame, whose machine base and forming machine base is separate, so that can produce more profiles in future.
