Grooved Feed Barrel used to getting good shear and best transportation of material. Because of Co-efficient, granules and screw and barrel have higher friction to get proper melting of the material, It’s useful to have grooved feed in the barrel to processing polymers of Olefin group.Grooved Feed Barrel used to getting good shear and best transportation of material.
