This nitrided blown film extruder screw barrel is dedicated to various blown film & cast film equipment—including PE, PO, PP, PPO blown film machines, as well as PVC/TPU/PET/PBT film production lines. It has been verified by numerous customers: even when processing materials mixed with waste/recycled plastics or calcium powder, it maintains excellent plasticizing effect, with higher output than standard screw barrels on the market. We also offer high-speed blown film screw barrel options for efficient continuous production.
The JCD Series blown film screw barrel adopts high-quality materials (38CrMoAlA alloy steel, SACM645 chrome-molybdenum steel, or bimetallic coating) and precision processing. Its stable plasticizing performance and wear resistance make it suitable for both general and high-demand blown film scenarios.

Q: Can it handle materials mixed with waste/recycled plastics or calcium powder?
A: Yes—its optimized screw structure ensures excellent plasticizing effect even for materials containing 20%+ waste/recycled plastics or calcium powder, avoiding uneven melting and film quality defects.
Q: What’s the advantage of the high-speed blown film option?
A: The high-speed version is designed with a special thread structure, which improves extrusion efficiency by 15% while maintaining stable film thickness, suitable for large-scale continuous production lines.
Q: How long is its service life when processing abrasive materials (e.g., calcium powder)?
A: Thanks to 38CrMoAlA material + 168H nitriding treatment, its wear resistance is 20% higher than standard screws, with a service life of 12,000+ working hours for calcium powder-containing materials.
With 72-hour quenching and 168-hour vacuum gas nitriding processes, the JCD Series blown film screw barrel achieves precise straightness (0.015mm/1000mm) and stable hardness. Effectively solve the difficulty of unstable extrusion, low output and short service life when processing mixed materials, becoming the preferred component for blown film manufacturers pursuing cost-effectiveness and efficiency.
