Extrusion: steel metal on the closed extrusion Jane, end pressure, the metal from the die hole of the provisions of the extrusion processing methods are the same shape and size of the finished product;


Rolling: steel metal blank through the gap of a pair of rotating rolls (shapes), due to compression of the material roll reducing the section length increased, pressure processing method;
