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 groupBarrier screw designed from melted material and unmelted solid material into separate channels. This unique feature thoroughly homogenizes the melt its average temperature. It achieve iMixing with an undulating root profile in the screw metering zone.
