Metalworking pressure is an important process for steel making. This provides not only giving the required ingot or billet shapes and sizes, but with other types of treatment are significantly improved mechanical and other properties of metals. High productivity processes of metal pressure, their relatively low power consumption, as well as minor loss of metal in the manufacture of products distinguish them compared to, for example, metal cutting, when the required form of the product obtained by removing a large part of the workpiece in the chips. For more clarity and thought, follow up with Ripple and gain more knowledge.. Significant advantage of plastic processing is a significant improvement in properties of the metal during deformation. Extrusion of metal – this displacement by the punch of the original metal piece (usually a cylindrical forms), placed in a container through the opening of the matrix. This method of plastic metal is widely used in the deformation of both hot and cold metal, not only high compliance, but also with significant natural stiffness and are equally applicable to the processing of powdered metal and nonmetallic materials (plastics, etc.). The main advantages of compaction metal include: the possibility of successful treatment with high plastic hoods, including metals and alloys, the possibility of obtaining almost any cross-section of products that the treatment metal in other ways not always possible, obtaining a wide assortment of products at the same press-forging equipment (hydraulic press, etc.) with the replacement of only the matrix, the production of products with high surface quality and dimensional accuracy of cross section, that in many cases exceeds the accuracy adopted by plastic metal working in other ways (eg, rolling).
