A completely redesigned die for three-layer PVC foam-core pipe now makes pipe up to 500 mm diam. at throughputs up to 3300 lb/hr. This is the largest such die to date from KraussMaffei in Germany (U.S. office in Florence, Ky.), exceeding the previous limit of 400 mm and 2400 lb/hr. KraussMaffei designed the new KM-3L RK43 die with nesting layers like an HDPE pipe die and with novel heart-shaped-curve flow distribution, whereas KM’s smaller side-fed spider dies are built with overlapping, bolted plates. Foaming reduces overall pipe density to about 1.0 g/cc vs. 1.45 g/cc for rigid PVC, for material savings of about 30%. (859) 283-4366 • www. krauss-maffei.com
