The Tin Knocker line of sheet metal working machinery was specifically developed to meet the needs of the small to medium sized HVAC contractor and general sheet metal fabricators. The line is unique in that it is the only line which has all machines necessary to set up a complete HVAC or general sheet metal shop. Some machinery manufacturers make roll formers, but no shears and brakes. Others make slitters or beaders, but no shears, brakes, roll formers, notchers or CNC plasma machines.
