The Electric Coil Form machine is designed to produce bends in single-row coils or multiple single-row coils joined at one end. The machine handles round and flat-tube coils up to 60 inches wide and 3 meters long for large commercial HVACR applications. A single, vertically oriented bend arbor produces one, two, or three 90-degree bends, creating L-, U-, or box-shaped coils. The coil form machine is all electric, offering lower energy consumption, greater precision, and lower maintenance than hydraulic machines, claims the company. Radio-frequency identification (RFID) matches part data to the arbor cover to avoid forming the wrong radius and to prevent scrapping of expensive coils. Options available include slip sheets, coil length measurement, inside coil pusher, bar code scanner, and coil staging table.
