Grooved Feed Barrel Sleeve

It’s not possible to buy the grooved feed barrel sleeve separately, which is an integral part of the high-speed screw barrel.

This barrel has an inner wall with a groove ranging from 30 mm to 150 mm, with a linear or spiral groove. The outer wall has cooling water channels and a feeding window. In order to complete the assembly, it should be inserted into the water jacket of the barrel. >>Learn More About our water jacket

Grooved feed barrels increase friction in the barrel more effectively. Extruders use this to get faster feed rates, increase conveying capacity, and increase discharge speed. In order to improve feed efficiency when processing olefin polymers like HDPE, PP pipes, and sheets, the barrel must be slotted. Groove feed barrel sleeves are more precise and flexible. For more abrasive or demanding applications, HUACHEN Screw can offer nitriding, alloy insert sleeves, and SKD sleeves technology.
