OVERVIEW:
Extrusion
Extrusion is a continuous process through which parts of a fixed cross-sectional profile are made. Material is fed through a hopper into an extruder, essentially a rotating screw surrounded by a heated barrel, where it is mixed, melted and pumped through a die. The die gives the part its shape. From this zone you link to information on some of the more common extrusion methods, such as film, sheet, and pipe/profile/tubing
