Extrusion Machine

An extrusion machine is a device which pushes or pulls a material through a shaped die to form a continuous length of product with a preset cross section. The extrusion process is used to produce a large number of commercial products which include steel or copper wire, plastic tubing, plastic sheets, and many food types. Extrusion as a manufacturing process offers many benefits such as the wide range of complex cross sections possible and the ability to form brittle materials. Depending on the material used, an extrusion machine may form the material cold or hot with some types of materials being completely melted prior to extrusion.

The simplest example of an extrusion machine is a bakers piping bag. The bag is filled with icing and a fitted with a decorative piping nozzle. If the bag is squeezed, the icing fills the nozzle and is forced out or extruded as a continuous length with the same cross section as the shape of the nozzle opening. This is the same basic principle as industrial extrusion machines used to form many products using plastics, metals, and food or pharmaceutical ingredients. The only real departure from this simple example is in the complexity of the cross sections, the inclusion of hollow cores, and the fact that some machines draw the material through the die rather than pushing it.
