KraussMaffei Berstorff GmbH A KMD 114-32/P twin-screw extruder was integrated into a new coextrusion machine for Schuco Polymer Technologies KG.

Schuco Polymer Technologies KG, a long-time customer of KraussMaffei Berstorff GmbH, has purchased a twin-strand coextrusion line for its plant in Weissenfels, Germany.

In the project, a KMD 114-32/P twin-screw extruder that has been running in the plant for more than 10 years has been integrated into a new coextrusion combination, which is also equipped with two KMD 63 K/P conical machines.

Shuco is using the line to make coextruded window profiles, with an output of about 1,700 pounds per hour. The main extruder prepares the material with a higher proportion of recycled fiber content for the inner layer. The two extruders, set up in a piggyback layout, deliver the outer layer in the twin-strand with an output of up to 440 pounds per strand.

KraussMaffei Berstorff is based in Hanover, Germany, with its US unit, KraussMaffei Corp. headquartered in Florence, Kentucky.
