Leading extrusion systems supplier Cincinnati Extrusion exhibit its latest developments in the field of Wood-Plastic Composites at Ligna (May 18 to May 22), the leading fair for wood processing industry in Hanover, Germany. The company has designed latest new extruder model for the production of Wood-Plastic Composites, Fiberex twin vent A135-37D. The model is the company's first parallel, counter-rotating twin-screw extruder for this market, extending its range of conical machines by adding a particularly powerful parallel model. The machine houses two active degassing units, each equipped with a vacuum pump and a double filter for in-production purification, enable an effective removal of moisture from the processing zone and adding to high end-product quality. Materials to be processed include ready-made blends of WPC compounds and WPC agglomerates based on PVC, PE or PP, as well as grinding stock from production, often with a relatively high moisture content. A long service life for the extruder is ensured by the tungsten carbide bimetal coating on both screw and barrel.
Product features, outstanding product characteristics and new design possibilities are the drivers of these materials, which represent one of the fastest growing segments within the global plastics industry. Together with the partner companies Beologic, Greiner Extrusion, Kompetenzzentrum Holz and Tech-Wood, Cincinnati Extrusion will present viable opportunities to enter and successfully start a business in Wood Plastic Composites. Following the North American example, the worldwide Wood-Plastic Composites market is becoming increasingly dominated by outdoor applications, such as decking, railing or siding. Up to 25 % annual growth rates are reported in Europe and Japan.
