Friction Forging Screw Press (Down Stroke)

These Friction Forging Screw Press (Down Stroke) are preferred for hot forming ( Forgings) and cold coining, stamping, embossing, sizing non-ferrous metals. The press body is steel welded construction one-piece box type design. After the welding the press body is glowed free from tension. The screw is made of high quality alloy steel and is heat treated to have great hardness at the same time great elasticity . Flywheel screw presses machines of this type are characterized by the fact that flywheel connected to accelerates at the start of working stroke and then braked to a standstill by the actual forming process. Thus the entire kinetic energy stored in the flywheel released screw press have not kinetically fixed bottom dead center point in common with drop forgings it self or by stops in the tool in tern, this results in advantage tool height adjustment is eliminated, Forging accuracy is greater. Forging is possible in closed die as screw cannot jam under load.
