Extrusion
Extrusion is a manufacturing process used to form and reshape plastics using pressure as the active principle. Heat is used to bring the material in a cylinder to the plastic forming temperature.
A punch then presses the hardening material through the cylinder, at the end of which a die is attached. The shape of the resulting profile is determined by the openings in the die.
Continuous material can be produced in a wide variety of shapes using extrusion. In addition to rods and tubes, the process can also produce complex geometries. With low tool costs and little material loss, the process offers very good cost-effectiveness.
#1 Definition Extrusion
Extrusion is a forming process in which shapeless plastic is given its permanent shape by a die under the effect of pressure and heat.
#2 Importance of extrusion
Extrusion has been used in plastics processing since the late 19th century. Today, the process is one of the most important manufacturing methods for the production of plastic hoses and profiles.
