Abstract
Screw design technology is considered to be empirical and secretive. The production rate of single-screw extruders is often limited by the melting capacity. The melting capacity of a screw depends on the polymer properties, the processing conditions and the particular geometry of the screw. Once the melting capacity is predicted, the screw can be designed to match the melting capacity. This paper presents a scientific approach to screw design based on an analytical melting model, with an example.
