Why UET Twin Screw Extruders Outperform
Every design decision targets one goal: a more uniform melt at a lower cost per kilogram with maximum reliability.
High Torque Density
Deep screw channels and high torque grade (up to 18 N·m/cm³) push output up without raising screw speed or melt temperature.
Modular Barrel & Screws
Swap screw elements and barrel sections to change recipes — changeover time cut by 30% with quick-release clamps.
±1.5°C Temperature Control
Independent zoned heating/cooling with PID control protects heat-sensitive materials like biodegradables from degradation.
Superior Mixing & Dispersion
Optimized kneading block geometry delivers uniform color strength and high-load filler dispersion (up to 85% CaCO₃) without over-shearing.
Wear-Resistant Core
Bimetallic barrel (HRC 58-62) and powder-metallurgy screw elements extend service life 3x in abrasive, high-fill applications.
−15% Specific Energy
Efficient gearbox and optimized screw profiles lower kWh/kg versus conventional twin screw designs — save $8,000+/year.

Expert Answers
Twin Screw Extruder Questions, Answered by Engineers
Get clarity on technical specs, pricing, lead times, and performance
What is a twin screw extruder used for?
Twin screw extruders are primarily used for compounding — intensively mixing polymers with fillers, pigments, additives, or blending different resins. Common applications include: masterbatch production (filler, color, additive), engineering plastics modification (glass fiber reinforced PA, PBT), biodegradable plastics (PLA, PBAT), cable compounds (XLPE, LSZH), and PVC compounding. They excel where high mixing quality, devolatilization, or reactive extrusion is required.
How do I choose between UET-B, UET-D, and UET-Max series?
Choose based on your material and output needs:
• UET-B: Standard torque (6.5-9 N·m/cm³) — best for color masterbatch, low-fill compounds (<50% filler), and budget-conscious buyers. Output: 80-1,500 kg/h.
• UET-D: High torque (10-12 N·m/cm³) — ideal for high-filler masterbatch (70-85% CaCO₃), engineering plastics, and 24/7 production. Our best seller. Output: 150-2,500 kg/h.
• UET-Max: Ultra-high torque (13-18 N·m/cm³) — for maximum throughput, cable compounds, reactive extrusion, and the most demanding materials. Output: 200-4,500 kg/h.

What L/D ratio do I need for my application?
L/D (Length-to-Diameter) ratio affects mixing quality and residence time:
• L/D 28-32: Simple blending, low-viscosity materials, basic color masterbatch
• L/D 32-40: Filled compounds (CaCO, talc), glass fiber reinforcement, standard engineering plastics
• L/D 40-46: High-filler masterbatch (80%+), reactive extrusion, devolatilization (removing moisture/volatiles), difficult dispersion
Most customers choose L/D 36-40 as it offers the best balance of mixing and cost. We can customize L/D at no extra charge for orders over $50,000.
