Looking for a high output reprocessing solution? Davis Standard’s extrusion capabilities for reprocessing combine innovative technologies for recycling the waste stream into a reusable product.
Our range of single screw and twin screw compounding and reprocessing systems address key efficiency factors such as: solids feeding and conveying, venting and devolatilization, compression and melting, polymer homogenization, and process controls.
Within our extrusion recycling technology line is scrap-reclaim and wide-mouth feed technology, ram stuffer and scrapper extruder options and complete reclaim systems. Heavy-duty gear reducers, customized feed throats, single or multi-venting options and process feed systems are just a few ways we can give you a competitive advantage.
In the area of extrusion technology for film reprocessing, Davis-Standard supplies extrusion systems that offer versatility for turning low bulk density film waste into a useable product. Extrusion systems typically include the extruder, a melt filtration device, pelletizing unit and material handling system. Material size reduction and transfer conveyors can be customized depending on application. Our relationships with major melt filtration and pelletizing suppliers ensure system continuity.
Our Ram Stuffer extruder model is specifically designed for processing the broadest range of feed stocks. This includes everything from light bulk density fluff to shredded flakes, and even heavy bulk density, regrind materials. The Ram Stuffer extruder uses a pneumatically actuated plunger to force the material into the feed section of the screw. The feed section has grooved technology to enhance the conveying of the feed material into the extruder barrel. In a similar way, our scrap reclaim extruder model uses the same wide mouth feed throat design as the Ram Stuffer without the pneumatic plunger. This affords a lower cost alternative when the feed material is slightly heavier in bulk density.
