Extrusion and Drawing

Extrusion is a plastic deformation process in which material is forced under pressure to flow through one or more die orifices to produce products of the desired configuration. This process provides a practical forming method for producing a limitless variety of parallel-surfaced shapes to meet almost any design requirement. Other advantages include improving the microstructure and physical properties of the material, maintaining close tolerances, material conservation, economical production, and increased design flexibility.

Drawing is a process of cold forming a flat precut metal blank into a hollow vessel without excessive wrinkling, thinning, or fracturing. The various forms produced may be cylindrical or box shaped, with straight or tapered sides or a combination of straight, tapered, and curved sides. The parts may vary from 1/4" (6mm) diam parts or smaller to aircraft or automotive parts large enough to require mechanical handling equipment.
