Horizontal Twin Cylinder Extruder for Welding Electrodes The Extruder is equipped with a hydraulic cylinder, hydraulic pump, pressure control valve and directional control valve. The piston has a fast return stroke to enable fast raffling of the paste cylinder. The paste cylinder has dia meter of 150 mm and the stroke of the paste piston is approximately one meter The following is the mechanism of operation of the wire feeder / extruder. The pieces of wire which are ejected from the wire feeder at high speed pass through the press block and there after through the coating die. Simultaneously the paste is compressed through the press block, takes a right angle turn and covers the space between the coating die and the wire. Thus the bare get the coating. #Electrodes Twin Cylinder Extruder #Process of Welding Electrodes #Process of Extruder
