Front Cover : In article number 2000340, Dagmar R. D'hooge and co‐workers highlight both the experimental and theoretical capabilities to control extrudate die swell for polymer material production by extrusion, which is a leading technology in the materials engineering field. Swelling takes place as polymer molecules are viscoelastic, implying that when they exit the extrusion equipment they recoil changing the dimensions and thus the product stability.
