The tribological data is required to take into account the conveying of solids in the feed zone. A distinction is made between the values for the friction of the plastic on the barrel wall $μ_z$ and the screw $μ_s$.

The problem here is obtaining the necessary friction coefficients. It is advisable to determine the necessary data by conducting your own series of tests.
