Abstract
Extrusion processes are widely used in plastic industries that aim to produce advanced solutions for increasingly sophisticated demands for plastics. Processes are not designed based on professional engineering design process, but on trial and error techniques. These two factors affect the extrusion processing parameters. In this study focus will be concentrated on the parameters incorporated in Polypropylene rope extrusion process such as: screw length, screw diameter, metering zone length and flight depth. A model equations were derived considering the swelling occurs for the extruded fibers and the tensile drawing of fiber. The authenticated design parameters was derived and a model useful to simulate any given process successfully was resulted in a form of computer software system.
