quality and component life. e ign t at perform. u ion™ cre . New barrier screw delivers higher throughput at lower melt temperatures than earlier barrier designs. Has proven its benefits in processing polyolefins, PET, ABS and PLA in various extrusion and blow molding processes. Nordson XALOY can modify any extruder to extend or shorten its L/D ratio to cope with changed process requirements. We engineer and deliver complete retrofit packages including a compatible screw and barrel suitable for your process plus heater bands, cover modifications and front barrel support modifications, as required. f cient™ cre . This barrier screw has proven its value in more than 30 years of field trata lend® i er. Low-shear distributive mixer produces a melt of uniform temperature. It’s highly suitable for processing shear-sensitive engineering resins such as polycarbonate or ABS as well as polyolefins and materials containing high levels of colorants, fillers or glass fibers.

Extrusion Screws S eci c tions se Nordson XALOY screws are typically manufactured from a 4000 series alloy, (usually 4140), nitriding steel (Nitralloy 135M), CPM tool steels, or any grade of stainless steel depending on the application. Certain applications require the use of stainless steels or special alloys for better resistance to corrosive wear. However, these screws require a secondary treatment to provide better resistance to wear (see Hardsurfacing Materials Chart).
