Extrusion Screw

4" diameter extrusion screw made from 17‐4PH H1150 stainless steel, hard-faced flight O.D. for increased life. Screws are available slotted or continuous based on the type of material to be processed. Screw can also be bored for cooling or heating.

Extrusion Barrel

Available with serpentine flow channels or open jacket for liquid heating or cooling, and without jacket for electric band heating. Barrels are available with smooth or grooved, hardened Stainless Steel liners, with or without mixing pins. Barrels can also be manufactured to accept pressure/temperature probes.

Packing Screws

Counter-Rotating Packing Screws provide a positive feed with a consistent flow of packed material, minimizing starvation and non-uniform extrudate. Packers allow one extruder to process a wider range of materials, eliminating added capital equipment cost.
