Monoextrusion Dies for Thermoplastics

After having developed the fundamental theoretical considerations for the design of flow channels of extrusion dies in the preceding chapters, now in Chapter 5 the focus will be on types of design, applications and the layout of dies for the discharge of a single melt. These will be referred to as monoextrusion dies in contrast to coextrusion dies (see Chapter 6). In discussing this subject, the extrusion dies will be divided into groups according to the geometry of their exit cross section since as a rule dies with similar exit cross sections are practically equal in the way they are constructed, regardless of the extruded product.
