German company unveils conical screw extruders

German manufacturer of processing plastics machinery Krauss Maffei has unveiled its new KMD53 K/P conical twin screw extruders, an addition to the company's series of extruders for the medium output range.

The new KMD53 K/P has the capability to extrude profile cores and outer layers with a combination of virgin and recycled resin plus fillers.

Krauss Maffei Profile Extrusion director Peter Oswald said based on the core, layer and combination technology, the machine combinations are suited to window profiles, ferret.com.au reported.

According to Krauss Maffei, processors are increasing their use of fillers for the production of the unseen profile core, which is enclosed by a thin external layer of a new colorfast material.

The process concept of parallel and twin screw extruders allows different formulations processing with one screw geometry and ensures optimum melt homogeneity.

The molybdenum plated screws are suited for processing recyclables and dry blends and when combined with the deep nitride barrels, can provide active wear resistance.
