An extrusion screw is always designed with the highest through put in mind. Profile, Sheet, Pipe, blown film or any extruded product the screw will be designed to allow for the max out put. In extrusion getting the pounds out per hour is the most important thing but the screw is always set for the highest out put available allowed for the material that is running. So like all extrusion screws the mixers, compression ratio’s, L/D, Barrier fights and different tool steels will all be used to get the best material quality, mix and flow for any application.

Material of the screw is very important and depending if you are running PVC, Linier Low, Poly Carbonate or PE every material has it own needs and screw design to gain the best flow through the die head. Wall thickness will always affect the flow. The thinner the better so the screw needs to be designed with a lot of details to make sure you have complete control over the process.
