Cincinnati Extrusion: Plant for Poland
KNG Awans Sp. z.o.o., Czarnków, Poland, is a producer of water, sewage and pressure pipes made from PE 100, PE 80 and PVC, as well as PVC pipe fittings for the domestic market. Several plans had already been in existence for expanding the production capacity, but the limited length of KNG’s production hall had presented serious problems. With the KryoSys line now ordered from Cincinnati Extrusion GmbH, Vienne, Austria, however, the Polish company can produce PE-HD 3-layer pipes with a thin outer PP-H layer in diameters from 90 to 630mm and a layer distribution of 25% / 50% / 25% on an extrusion line almost halved in overall length.
The line consists of two monos+ 60 single-screw extruders for the two PE-HD layers and a talos 45 as co-extruder for the thin outer PP-H layer. The pipe head, a KryoS 63-1200 3-Coex, ensures excellent distribution accuracy while keeping the length of the entire line short thanks to its integrated melt cooling system.
