Six Engineering Solutions for PVC Processing
PVC’s thermal sensitivity and corrosiveness demand specialized engineering. We address six critical challenges that generic extruders cannot solve.
Thermal Degradation Prevention
Independent PID heating zones maintain ±0.8°C across all barrels, preventing PVC decomposition above 200°C and eliminating char or discoloration defects.
Dimensional Precision Control
Calibrated die systems with closed-loop haul-off synchronization achieve ±0.02mm tolerance on profiles, lifting batch qualification rates significantly.
Uniform Plasticization
Optimized screw geometry with mixing elements fully gelates powder compounds without over-shear, ensuring mechanical strength and surface quality.
Energy Consumption Reduction
High-efficiency motors, ceramic heating elements, and smart standby modes cut specific energy use by up to 35% while maintaining production output.
Rapid Changeover Systems
Quick-clamp die bases and 120+ stored process recipes enable product or color changes in under 12 minutes, minimizing production downtime.
Corrosion Protection
Nitrided 42CrMo screws and hardened barrels resist HCl attack from PVC decomposition, extending service life and reducing maintenance frequency.

How a UET PVC Extrusion Line Works
Six continuous stages transform PVC compound into finished products with consistent quality.
1. Precision Feeding
Volumetric or gravimetric feeders meter PVC compound into the extruder throat at controlled rates, ensuring consistent material input.
2. Controlled Plasticizing
Rotating screw conveys, compresses, and melts the material at 160–200°C through independently heated barrel zones with PID control.
3. Die Forming
Molten PVC passes through precision-machined die heads that shape it into the target profile — pipe, window frame, or panel cross-section.
4. Vacuum Calibration
Vacuum calibration tanks with cooling water set exact outer dimensions while the profile solidifies, ensuring dimensional accuracy.
5. Synchronized Haul-Off
Variable-speed haul-off units pull the profile at synchronized rates, with planetary saws or automatic cutters achieving ±1mm length accuracy.
6. Automated Stacking
Auto-stackers or coilers collect finished products, ready for quality inspection, packaging, and shipment to customers worldwide.

PVC Extruder Technical FAQ
Professional answers from our extrusion engineering team.
How does a PVC extruder work?
PVC compound (powder or pellet) is fed into a heated barrel where a rotating screw conveys, compresses, and melts it at 160–200°C. The melt is pushed through a die to form the target shape, then sized in a vacuum calibration tank, cooled, hauled off, and cut to length.
Single screw or twin screw: which is right for PVC?
Single-screw PVC extruders usually process pre-compounded pellets and suit pipes and simple profiles at lower investment. Twin-screw (especially conical twin) extruders process PVC powder directly with superior mixing and venting, ideal for rigid profiles and high-output lines. UET engineers recommend the configuration based on your formulation and product.
Why is temperature control so critical in PVC extrusion?
PVC has a narrow processing window and begins to degrade above ~200°C, releasing HCl and causing discoloration or black specks. UET’s closed-loop PID control holds ±0.8°C across every heating zone, keeping the melt stable and degradation-free.
What products can a UET PVC extruder produce?
Rigid and flexible PVC pipes from 20 to 300mm, window and door profiles, wall panels and foamed boards, electrical conduits, decorative trims, and PVC compounds/pellets. Switching products mainly requires changing the die head and downstream auxiliaries.
What output can I expect from each model?
UET-50 delivers 50–100 kg/h, UET-65 delivers 100–200 kg/h, and UET-80 delivers 200–350 kg/h. Actual output varies with formulation, die design, and downstream equipment; we confirm guaranteed output in every proposal.
Can the extruder process recycled PVC?
Yes, within limits. Recycled PVC with stable melt flow can be blended with virgin material; for high regrind ratios we recommend an adjusted screw geometry and melt filtration. Share your regrind percentage and we will specify the right configuration.
What maintenance do the screw and barrel need?
The nitrided 42CrMo screw (≥600 HV) and hardened barrel resist PVC’s corrosive melt for years of service. Routine tasks include cleaning the die at changeover, checking heater bands and thermocouples, and following the gearbox oil schedule.
What auxiliary equipment completes a PVC extrusion line?
A typical line adds a die head, vacuum calibration tank, cooling section, haul-off, cutter, and stacker; compounding lines may also add mixers and auto loaders. UET supplies complete turnkey lines including installation, commissioning, and operator training.
