Explanation: Hot extrusion is the process of heating appropriate metals and alloys to the right temperature and then inserting the heated stock into the cylinder of an extrusion press to produce a finished product. Using the pressure created by a moving ram or piston, plastic metal is forced through a die that has been designed specifically for it.
