The processing of metals by pressure includes technological processes, as a result of which the shape of a metal workpiece changes without disturbing its continuity due to the relative displacement of its individual parts, that is, by plastic deformation. In the processing of metal by pressure, the ability of metals, under certain conditions, under the influence of applied external forces, to change, without collapsing, the size and shape and retain the resulting shape after the termination of the forces, is widely used.

When metal forming by pressure, the loss of metals is less compared to other types of metal processing, so this method of metal processing is expanding. In addition, in the processing of metals by pressure, it is possible to ensure a high level of mechanization and automation of technological processes.

Processing of metals by pressure can produce products with a constant or periodically changing cross-section (rolling, drawing, pressing) and piece products of various shapes (forging, stamping), corresponding in shape and size to finished parts or slightly different from them.
