LUIGI BANDERA 2B HTS Counter-Rotating Parallel Twin Screw Barrel

Core Technical Advantages (PIPLL Fully Replicated & Optimized)

· PIPLL replicates the industry-proven 28D optimal L/D ratio, delivering plasticization degree ≥98%

· PIPLL adopts the pre-positioned 20L/D vent design, reducing shear heat and PVC degradation, cutting stabilizer usage by over 10%

· PIPLL implements the segmented functional design for efficient degassing and stable pressure build-up, producing defect-free products

· PIPLL’s deep channel positive conveying system ensures pulse-free feeding, handling 60-80 phr calcium carbonate formulations reliably

Modular Quick Changeover System

PIPLL manufactures standard-length modular barrels with flange connections, allowing independent segment replacement and lower maintenance costs. PIPLL also customizes module combinations to meet your existing production line retrofit requirements.

High-Efficiency Devolatilization & Precision Temperature Control

PIPLL equips all compatible units with 1-2 deep channel vacuum venting sections (≥-0.095MPa) to efficiently remove moisture and volatiles. PIPLL can customize vent number and position based on your specific material characteristics.

PIPLL Comprehensive Graded Wear-Resistant Material System

· Medium Wear: PIPLL uses PTA Ni60 screw flights + centrifugal Ni-based barrel liners (HRC 58-62), 3-4x longer life than nitrided steel

· High Wear: PIPLL provides WC-coated screws + WC-Ni barrel liners (HRC 65-68), ideal for >80 phr fillers and recyclates, lasting over 50,000 hours

· Special Conditions: PIPLL offers SS316, Hastelloy and other corrosion-resistant options for medical and chemical applications

PIPLL Strict Precision Manufacturing & Quality Control

· PIPLL polishes all material contact surfaces to mirror finish (Ra ≤ 0.4μm), eliminating dead spots and simplifying cleaning

· PIPLL achieves screw concentricity ≤ 0.015mm and meshing clearance ≤ 0.02mm, ensuring smooth operation with noise ≤ 78dB

· PIPLL conducts comprehensive pre-shipment testing on every unit, including material spectroscopy, hardness and dimensional inspections
