Melt temperature in extrusion affects most aspects of the process, including polymer integrity, ability to handle and cool the extrudate and surface finish of the final product. Attempting to control the melt temperature via adjusting extrusion settings on a single screw extruder has a varying success rate, depending on such factors as: screw speeds being attempted, screw design, polymer viscosity and screw tip pressure.
This paper will give the results of a study including the above mentioned parameters and the melt temperature control possible on a single screw extruder. Most extrusion engineers have a feel for their ability to control melt temperature with their machines and polymers, but an encompassing study will clarify the degree of control possible on this machine under a broad array of conditions.
