Screw construction is hard faced, nitrided or hardened & nitrided, for highly abrasive materials we can supply screws with Tungsten carbide coatings on the flight flanks and core diameters, or in the case of highly corrosive polymers such as Fluoropolymer a Duranickle based screw is offered.
Designs are available for single flight metering screws, single barrier screws, double barrier screws, variable pitch flights, multi start flights and slotted flights. Two stage screws for vented extruders are also offered.
Mixing sections, the more common of which, include Maddock (spiral or straight), Hoechst, dulmage, pinned, pineapple or combinations of these designs are available.
Our capacity ranges from 25mm up to 200mm depending on L/D ratio.
