Multiple-Layer Extrusion (Coextrusion)It is becoming more common to combine multiple layers of different polymers to form products with properties that take advantage of the best properties of each component. For example, packaging film might be composed of several different types of polyethylene al

Dies with annular cross sections are used to extrude pipes, tubes, tubular films, and parisons for blow molding. Center-fed dies are commonly used for extruding pipes, while side-fed dies are used for tubular films and parisons. The four basic annular die designs in use at the present time are shown

Profile Extrusion DiesProfile extrusion refers to the extrusion of polymer melts through dies of cross sections that are neither round, annular, or rectangular with an aspect ratio, W/H, greater than 10.0. At present three types of profile dies are used: orifice dies, multistage dies, and tapered pr

Extrusion allows the conversion of raw polymeric material (in the form of pellets) using three main steps: melting, forming, and cooling. Among these, the first one represents the most energy-intensive. The primary consumers of electrical energy in extrusion plants are motors and heating devices. Ba

Screw extrusion is one established processes for plastic/polymer recycling and processing. Commercially, both single-screw and twin-screw extruders are available for polymer processing. The use of single-screw extruders in production processes has progressed significantly over the past decades. In t
