  • The Plastic Profile Extrusion Process Explained | Petro ...

    Plastic Extrusion. Extrusion is a manufacturing process used to create long objects of a fixed cross-sectional profile. The material, which can be plastic, metal, ceramic or foodstuffs, is drawn through a die of the target profile shape and forms a continuous length of that shape.
