HBM Packaging & Plastics Technologies provide distribution services for a range of plastic profile extrusion systems manufactured by Krauss Maffei Extrusion of Munich. HBM Packaging & Plastics Technologies represent Krauss-Maffei Extrusion in Oceania.
Aluplast GmbH of Karlsrube, Germany, are manufacturers of PVC window systems. They currently operate more than 45 extruders in their production plants around the world.
Krauss Maffei Extrusion have installed a range of plastic extruders at Aluplast’s manufacturing plants. Aluplast were restricted in their floor-space and required extruders that were compact and could be flexibly installed, so they could be moved if necessary. Krauss Maffei Extrusion worked closely with the company and developed a number of different solutions, including using a combination of two 90-32/P twin-screw extruders with a KMD 50 K/P as co-extruder. This particular configuration used only 2.5m x 5.4m floor-space.
Krauss Maffei Extrusion adopted space saving innovations including positioning the main switching cabinet for each unit at the end of the unit and installing small switching cabinets with the necessary control zones and operator panels near the die.
Krauss Maffei Extrusion also installed converters for the water-cooled AC motors over the gearbox. The switching cabinet for the co-extruder mounted on rollers and can be moved aside to allow access to the main motor. The two main extruders can be controlled together or separately by a defined master.
Aluplast’s compact, double strand system for extruding core-technology window profiles achieves a throughput of over 900 kilograms per hour.
