Extrusion International 2-2026

35 Extrusion International 2/2026 ensure that quality parameters are maintained. This enables the material-saving and highly ef cient extru - sion of microducts and sheath pipes. This also includes the addition of colours and production and product- optimising additives. Here, too, a rather unusual but optimal combination of devices was developed for this application: the hopper scales measure the through- put gravimetrically, i.e. based on weight, and transmit the signal to the extruders or gravimetric dosing de- vices. This guarantees both cost-ef cient and optimal feeding of the extruders with very low tolerances for the end products. Almost 2,000 metres of piping for transporting gran - ulate, mostly with a diameter of 60 millimetres, con- nect all plant components between silos and conveyor equipment at the extruders. Integrated into the system are dust extraction systems, comprehensive sensor tech- nology and control and monitoring technology tailored precisely to egeplast's requirements, with interfaces to production management and ERP systems. Ef ciency, safety, competitiveness Automation and digitalisation not only bring signi - cant increases in ef ciency, but also safety: it is now very easy to assign material batches to individual products. The motan control system automatically ensures that a production order is prioritised according to batch purity and that the silos are emptied, keyword ‘ fo’. „The extrusion lines are very durable and powerful, so we chose high-quality peripheral technologies to match,“ explains Torsten Ratzmann. The central ma- terial supply system also has to cope with the wide variety of variants, which is actually atypical for pipe production, and that was a real challenge – especially since there were less than 18 months between the start and the actual operation of this large project, including the construction of the hall. What we have created here also serves as a blueprint for other plants in our group." In the process, solutions were devel- oped on a large scale that are unique in the indus- try to date. There are no off-the-shelf systems here, but rather highly efficient systems precisely tailored to specific requirements – from material storage and central supply to the extrusion lines to the technology for winding the individual pipes and storing them in a fully automated warehouse. This relieves employees of routine tasks and makes better use of their quali- fications. Training in automation and programming is now car- ried out almost exclusively in-house. There is constant feedback between these employees and motan in order to gradually optimise organisation and production and guarantee the long-term competitiveness of the beauti- ful Münsterland region. motan gmbh Otto-Hahn-Str. 14, 61381 Friedrichsdorf, Germany www.motan-group.com egeplast international GmbH Robert-Bosch-Str. 7, 48268 Greven, Germany www.egeplast.de SURFACE TREATMENT Precise solution for egeplast: Dosing and mixing system with Minicolor G dosing device and BTW hopper scale (Source: motan) Material supply via the extruders with Metro G conveyor devices and intermediate containers above the machine level (Source: motan)
