Nylon is a typical engineering plastic raw material for spinning and extruding plastic fibres. Modified PA6, PA66 are common staple and filament fibre raw materials. Extruding nylon with a conventional feed screw is difficult because nylon becomes liquid when heated. This screw barrel set can lead to inconsistent spinning and insufficient feed. HUACHEN Screws offers single screw barrel sets that are specifically designed for PA6 PA66 nylon staple and filament fibre extrusion.
1. The screw barrel set is made of high quality 38CrMoAIA alloy steel, after quality tempering, finishing, and surface nitrogen treatment. Furthermore, screws are available with hard chrome plating and bimetallic alloys overlaid on the surface of the screw. The barrel was cast using centrifugal casting, the most advanced production method. So the PA fibre screw barrel set has high wear resistance, corrosion resistance, long service life, and other characteristics.
2. It is mainly used for spinning melts for nylon PA6, PA66, and other chips. The extrusion screw is designed with LTM low temperature mixing elements for better plasticizing performance. Grooved feeding barrel is available with forced feed systems that provide efficient feed capacity. High manufacturing accuracy and straightness are achieved by using specialized machining technology for the screw and barrel. Every screw barrel set produces consistent performance when extruding PA nylon fibres.
