Screw Design Evaluation, 1991 Polymers, Laminations & Coatings Conference Proceedings
Paper will cover current basics of screw design and give a practical approach to users for evaluating existing screw performance, as well as projected new screw performance with respect to capacity, shear, homogeneity and power requirements.
Paper will also cover the sensitivity of a screw to wear and with discuss metallurgical and manufacturing techniques for proper screw manufacturing, including discussion of the latest developments of materials with respect to polymers and additives.
The requirements in extrusion lamination and coating processes are basically the same as those in other continuous polymer processes with some particular features such as high melt temperature and low viscosity to warrant a good and uniform adhesion.
Performance of the screw with respect to the applied torque and the extruded polymers will be analyzed.
