Extrusion?Solutions?for?Wood-Plastic?Composites
Wood-plastic composite decking products continueto show exponential growth in the marketplace as an alternative to traditional wood decking, and today’s strongmovement towards outdoor living spaces is fueling this growth.
Leading wood-plastic decking producers use ENTEK extruders, and not justbecause of the company’s high performance co-rotating twin screw extruders.ENTEK’s expertise in overall plant operations has helped decking producers makehigher quality products with their materials, increase line production capacity, and grow their businesses and profitability.
If you are working with wood-plastic composites, contact ENTEK today to find outhow we can help you achieve your goals of:•easier start-ups
•cost-effective delivery of resin, wood fiber and additives to the process•higher productivity•higher performance
•systems integration with all key elements at your plant
Besides providing state-of-the-art twin-screw extruders, ENTEK offers turnkey solutionsfor your entire processing plant. Our engineers have helped numerous customersestablish complete plant-wide operations, often from the ground up.
Whether you’re looking to add an extrusion line, considering a plant expansion, orplanning an entirely new production facility, ENTEK is field-proven and has the experience to help. And we do it with no strings attached – unlike other suppliers,ENTEK does not require fees or licenses for the use of its technology.
The schematic pictured below illustrates a typical layout for an ENTEK wood-plasticcomposite system for producing deck boards. If fiber-plastic composites are your busi-ness, we would like to talk with you. We’re confident we can partner with you toimprove your productivity and as a result, improve your bottom line.
Loss in Weight Feedersfor accurate formulation and steady state operations. Feeder controls are fully integrated into the extruder controls.
E-MAX™ Twin-Screw Extrudersfeature segmented barrels and screws for
optimization of any formulation. The co-rotating design yields excellent dispersive and distributive mixing for high throughput and consistent finished product.
Melt Pumpfor pressure generation and control. Allows for combined compoundingand direct profile extrusion.
Diescan be ENTEK or customer supplied. ENTEK will supply all adapters to connect downstream equipment to the outlet of the extruder.
Cooling Tanksuse water drench cooling for maximum heat transfer. The cooling tankis closed loop with pump, filters and heat exchanger. Rollers are powered by a beltdrive, helping to move the profile along and reducing stress on the profile for betterdimension control.
Servo Cuttersallow for precise manual or automatic cutting of profiles. A rotary
encoder compensates for fluctuations in product speed to maintain accurate cut lengths.Surface Finishingis highly customer specific. ENTEK will work with customers toincorporate the solution that best meets their needs.
Process Controlallows for continuous machine monitoring. Historical data can be compiled to help optimize the process and central alarming assists with
troubleshooting. Data files can be used in Microsoft Excel for auto process reporting.
The process begins with your materials. Your formula of wood flour orother natural fiber material, along with virgin or regrind plastic needs tobe tested, adjusted, and optimized, and this is where you’ll immediatelynotice the ENTEK difference. At our in-house lab in Lebanon, Oregon,we will work with you to run comprehensive trials of your material toperfect the process.
Industry Leading Throughput
Tell us your production goals, and we'll help you choose the bestENTEK extruder for your application. When you go into production,you can be confident that ENTEK extruders feature the highest outputrates in the wood-plastic composites industry. Our co-rotating twin-screws are designed for maximum throughput, and are constructedtowithstand the harshest material formulations and operating conditions. For high-volume deck and railing profiles made from HDPE or PP andwood, the E-MAX™103mm is an industry workhorse, achieving ratesof 3,000 to 3,500 lbs/hr or better day in and day out.
