Metalworking pressure is an important process for steel making. This provides not only giving ingot or billet required shape and size, but with other types of treatment are significantly improved mechanical and other properties of metals. High productivity processes of metal working pressure, the relatively low power consumption of, and insignificant loss of metal in the manufacture distinguish them compared to, for example, metal cutting, when the required form of the product obtained by removing a considerable part of the workpiece in chips. A significant advantage of plastic processing is a significant improvement in properties of the metal in the deformation process. Extrusion of metal – this displacement with the punch of the original metal piece (usually a cylindrical forms), placed in a container through the opening of the matrix. This way the plastic is widely used metal in the deformation in both hot and cold metals, which are not only high compliance, but also with significant natural stiffness and are equally applicable to the processing of metal powders and metallic materials (plastics, etc.). The main benefits of compression metal include the possibility of successful treatment with high plastic hoods, including maloplastichnyh metals and alloys, the ability to obtain virtually any cross-section of the product, handling metal in other ways not always possible, getting a wide assortment of products at the same press-forging equipment (hydraulic press, etc.) with the replacement of only the matrix, the manufacture of products with high surface quality and accuracy of cross-sectional dimensions that, in many cases exceeds the accuracy adopted by plastic metal working in other ways (eg, rolling).
