Extrusion International 6-2020

36 Extrusion International 6/2020 PIPE EXTRUSION – CASE STUDY Palad HY, which was founded in 1997, ranks among the leading manufacturers of HDPE and PVC pipes in Israel. The ISO 9001:2008-certi fi ed pipe producer is well known for its range of large-diameter pipes with maximum di- ameters of 1,200 mm for HDPE pipes and 500 mm for PVC pipes. In addition to its domestic market, Palad HY also serves customers in Eastern and Western Europe, South America and Africa, towhich about 25%of its annual pro- duction volume of currently about 20,000 t is exported. The company’s product range includes fresh water and sewage pipes as well as pipes for natural gas distribution systems, and protective conduits for electricity and com- munication lines. Palad has been a customer of battenfeld-cincinnati right from the beginning and now operates several lines with machines from the extrusion specialist. “In view of our positive experience with the machine technology from Germany, we have again chosen an extruder from battenfeld-cincinnati for our most re- cent investment, and we were not disappointed”, Rami Dweik, son of the proprietor and responsible for the production as Deputy Manager, reports. On the con- trary! The solEX NG 75-40 installed at the beginning of this year belongs to the new generation of high- performance single screw extruders from battenfeld- cincinnati. At Palad, it has replaced an old extruder in a PE 100 pipe extrusion line. “We are particularly impressed with the lower melt temperature compared to the previously used extruder, combined with better melt homogene- ity and consequently better pipe quality”, Fuad Dweik adds. Thanks to the lower melt temperature, Palad also achieves signi fi cantly more even wall thickness distribu- tions within extremely narrow tolerances, plus less un- desirable sagging. Of course, the better pipe quality also reduces material consumption and produces less scrap. “Both the material savings and the roughly 10% reduc- tion in energy consumption due to the lower heating rates make this extruder a particularly cost-ef fi cient alter- native”, concludes the General Manager, who is already thinking about a further investment in another solEX NG extruder of the new generation for other existing lines. The completely redesigned processing unit is responsible for the above-mentioned advantages of the newsolEXNG extruders, which are available with screw diameters of 60, 75, 90 and 120 mm and cover a throughput range from Ideal for Large-Diameter Pipes – Less Sagging, Better Quality Next Generation Extruder solEX NG “The most outstanding advantages of the new extruder are lowmelt temperature with high output” is how Fuad Dweik, Managing Partner of Palad HY Industries Ltd., domiciled inMigdal HaEmek, Israel, sums up his assessment of the recently commissioned solEX NG 75-40 frombattenfeld-cincinnati GmbH, Bad Oeynhausen. He is a long-standing customer of the Germanmachine manufacturer and was the fi rst pipe manufacturer in Israel to opt for the single screw extruder of the latest generation, which offers many additional advantages
