This document discusses different types of extrusion processes including forward and backward extrusion as well as direct and indirect extrusion. It explains extrusion can be done hot or cold and describes horizontal and vertical hydraulic presses used for extrusion. Examples of materials that can be extruded include aluminum and uses of extruded parts are mentioned. The principles of extrusion and limitations are summarized.
