DYMCO has concentrated our efforts on a suction conveyor and it is highly evaluated.
A conveyor transports material and objects off course , but at the same time it can exert traction on heavy cylindrical objects stably as below.
Metal sheet stays flat by suction and pull heavy material on it. Our suction conveyor transports rolled material as well as thin material piece by piece.
