These 38CrMoAlA nitrided twin screw barrel sections are core components for co-rotating parallel twin-screw extruders, specially engineered for EVA/POE solar film and high-end film production. Crafted from high-quality 38CrMoAlA alloy steel and treated with 168-hour vacuum ion nitriding, they form a uniform, dense nitrided layer that delivers exceptional wear resistance, corrosion resistance, and dimensional stability during continuous production.
For EVA/POE and other high-purity, high-uniformity film materials, the smooth surface and stable performance of these nitrided barrels effectively prevent material adhesion and degradation, ensuring film thickness uniformity (±0.01mm) and impurity-free quality that meets the stringent standards of photovoltaic, electronic, and other high-end applications.

Q: Why is nitrided treatment ideal for EVA/POE film production?
A: The ion-nitrided surface is extremely smooth and hard, which reduces material adhesion and avoids thermal degradation of sensitive EVA/POE resins—critical for maintaining film purity and uniformity in photovoltaic applications.
Q: How do these barrel sections improve film quality?
A: Their stable dimensional accuracy and uniform heat transfer ensure consistent material flow, directly translating to film thickness uniformity (±0.01mm) and eliminating defects like streaks or impurities that can compromise solar panel performance.
Q: Can these barrels be customized to fit my existing extruder?
A: Yes. We provide full customization based on your extruder model, barrel length, and installation parameters, ensuring seamless compatibility and optimal performance for your specific production line.
By combining precision machining with advanced ion nitriding technology, these barrel sections solve the core pain points of material adhesion, film defects, and frequent component replacement in high-end film production. They are the preferred choice for manufacturers of EVA/POE solar films and other precision thin films, delivering reliable quality and efficiency for critical applications.
