Follow-up order to extend capacities
Hamza Industry Co. is a long-standing and devoted customer, and has been using a KraussMaffei Berstorff direct extrusion line and other pipe extrusion equipment to produce pipes for several years. “Hamza is extremely impressed by the quality of our machines and the process engineering expertise of our company," said Andreas Kessler, General Sales Manager at KraussMaffei Berstorff. “Hamza therefore again made a clear decision in accepting our offer when it was necessary to extend its production capacities.
" The scope of the order comprises a KMG 81-40/R corotating twin-screw extruder as the main extruder for the filled middle layer, a KME 38-30 B/R coextruder for the thin internal and external layers, the KM-RKW 73 three-layer pipehead and downstream units for calibration and cooling. The system processes highly filled PP into pipes with a diameter ranging between 20 and 250 mm and at a maximum output rate of 700 kg/h./ line The pipe components are compounded using a special material weighing system and are extruded simultaneously as the finished pipe in the direct extrusion process.
Direct extrusion: Profit-maximizing and material-friendly
Direct extrusion is the combination of two process technologies, i.e. compounding and processing, in one step. This technology offers the processor significant advantages, for example potential savings on material costs, energy consumption and handling costs. The single-stage process also protects the pipe material since it only has to be melted once. Pipes containing a high proportion of minerals are used especially in building construction because they have excellent sound-insulating properties. |
