Description

Standard Operating Procedure (PDF)

Extrusion is a process by which a material is extruded into a constant profile shape through a die. This extruder can accommodate both single- and twin-screw applications. Single-screw extrusion uses one screw within a cylindrical barrel to continuously push the material through the die. Twin-screw extrusion is used to generate a superior mixture compared to single-screw extrusion. Two screws are used within a figure-8-shaped barrel. Twin screws are usually used to compound or blend two or more different materials.
