In this type of equipment, an Archimedean screw is used to pressurize material in a plastic state and force it through a suitable die. This principle is most widely used in molding and forming operations, such as with plastics [22] and structural clay products [9]. These applications are highly specialized and will not be discussed here since they are usually considered to be outside normal size enlargement techniques. 

A primary objective in preparing this book was to present a generalized account of the many size enlargement techniques scattered throughout these diverse industries, with emphasis on similarities and unifying characteristics whenever possible. A related objective was to allow the reader to understand the underlying principles so that successful techniques from other industries can be adapted to the application of his particular concern.
