- Product Detail
Single screw extruders are essential for producing polyester PET yarn monofilament. The yarn monofilament extrusion screw barrel is the core component of the polyester PET yarn monofilament extruder. Monofilament products’ performance and quality are determined by screw and barrel structural design and the strength of their materials.
Polyester PET yarn monofilament extrusion screw barrel
1. The screw and barrel are made from premium 38CrMoAlA. Processes using strict tempering and nitriding, the hardness of the screw barrel and various indicators of durability, allowing a longer service life. The screw and barrel are all machined using high precision CNC screw barrel milling machines. Each set of screw barrels has a high degree of consistency in extrusion.
2. With our large screw barrel machining equipment, we can quickly make quality large PET fiber monofilament extrusion screw barrels (D90, D105, D120, D160).
3. We offer three-stage monofilament screws and combination monofilament special screws as well. The screw and barrel feed section structure was optimized for stable feed and balanced output in the extrusion section, boosting plasticisation and extrusion efficiency. The melt will be compressed by increasing the melting and compression time. Monofilament will be more dense and homogeneous this way, ensuring quality.
4. We also offer special screws that can process recycled PET pellets for monofilament processing. Bimetallic alloy treatment and electroplating can be provided for transparent PET materials.
5. Screw and barrel construction ensures stable pressure fluctuations, stable temperatures, and stable extrusion volumes.
6. Screw barrels fit most models and are easy to install. You can also provide assembly information to our engineers for customizing your screw barrel.
