Manufacturing of Wood-Plastic Composites production of wood plastic composites with the An improved product quality, higher throughput rate and a broad processing range characterize Palltrusion™ technology. The Palltruder® produces an optimum end product: Granules with reproducible quality affecting a wide material spectrum - at low The granules produced, Pallwood®are further processed in additional production processes such as extrusion, injection moulding, pressing, i.e. P-Fix®, etc. into high quality end products.

granules with high bulk

Four main processing steps characterize Palltrusion™ technology: Metering of the components - natural raw material, plastic and additives, - palltrusion, cooling and screening. The technical characteristics of the system are convincing due to modular and compact design. Most modern control techniques guarantee a fully automatic continuous operation. The Palltruder® preferably processes material with a moisture content of up to 8 percent. Steam arising in the process is directed through a filter unit into the atmosphere by a vacuum device. Fines are automatically re-introduced The moisture content...

1. Knives 4. Pressure pieces 3. Pressure Disc 6. Cooling disc The mixing ratio, the type of plastic and the natural fibers as well as their moisture content are decisive for the throughput rate to be The effectiveness of the Palltruder® is improved by the integration of intelligent, gravimetrical sensor technology. The quality of the granules produced is kept constant by the stabilization Fibers from natural materials - especially wood flour, plastic chips or flakes, fibers or powders as well as lubricants and other additives are equally dosed into the Palltruder®. Frictional heat and high pressure,...

depending on feed material, moisture content and mixing ratio PALLTRUDER® Characteristics : • Produces dry, free-flowing and homogeneous granules with high bulk density • Flexible material choice and recipe • Continuous processing • Automatic start without preheating • High throughput rate, low energy consumption • Moisture content of the granules < 1%. 20-50% higher throughput rates possible on the Extruder
