We feel sorry for our Russia client. This order was confirmed in 2019. But we export this air fillter roll forming machine today.  We produced the similar order of Qatar air fliter frame making machine. The size of frame is different.  There are two pre punching system and one post punching in this roll forming machine line. So the control system must be accurate. The product is the shape of U channel, we use the four pieces U channel to make one square shape. So the punching location is important for this forming machine. We must keep four sizes in same length. Servo motor roll forming machine system and gear transmission system are used in Russia air filter frame roll forming machine.  Plc engineer write one professional system for  air filter frame making machine. We texted many days before shipment. We confirmed with our client that it is new line for them and we will supply video guide service when installing in their factory.
