These bimetallic overlay twin screw barrel sections are precision-engineered core components for co-rotating parallel twin-screw extruders, specially designed for lithium battery diaphragm production. Crafted from high-strength 38CrMoAlA/SACM645 alloy steel with a dense bimetallic overlay layer, they deliver exceptional wear resistance, corrosion resistance, and dimensional stability—critical for processing the ultra-pure PE/PP resins used in high-performance lithium battery separators.
The mirror-smooth inner surface and uniform bimetallic layer effectively prevent material adhesion, thermal degradation, and metal contamination, ensuring the lithium battery diaphragm meets stringent industry standards for thickness uniformity (±0.005mm), impurity-free quality, and consistent electrochemical performance.

Q: Why is bimetallic overlay critical for lithium battery diaphragm production?
A: Lithium battery diaphragms demand zero metal contamination and ultra-smooth material flow. The bimetallic overlay prevents base metal wear and eliminates the risk of metal particles entering the resin, while its corrosion resistance ensures long-term stability when processing sensitive PE/PP materials.
Q: How do these barrel sections ensure diaphragm quality?
A: Their precision-machined inner surface (Ra ≤ 0.4μm) and stable dimensional accuracy eliminate material dead zones and ensure uniform plasticization, directly translating to consistent diaphragm thickness and impurity-free quality—critical for battery safety and performance.
Q: Can these barrels be customized for my specific diaphragm production line?
A: Yes. We provide full customization based on your extruder model, barrel length, and process parameters, ensuring seamless compatibility and optimal performance for your lithium battery diaphragm production.
By combining high-strength alloy steel with advanced bimetallic overlay technology, these barrel sections solve the core pain points of contamination, inconsistent quality, and frequent component replacement in lithium battery diaphragm production. They are the preferred choice for manufacturers of high-performance lithium battery separators, delivering reliable quality and efficiency for critical energy storage applications.
