Twin Screw Dryer-Free Vented PET Sheet Extrusion Line

Product Overview

The CX Series Twin Screw Dryer-Free Vented PET Sheet Extrusion Line from Chenxing Machinery represents a paradigm shift in PET sheet manufacturing. Unlike traditional PET sheet production systems that mandate a separate pre-drying phase—costing manufacturers 4-6 hours of downtime, substantial energy expenditure, and dedicated dehumidifying equipment—our dryer-free design integrates moisture removal directly into the extrusion process via a specialized co-rotating twin-screw configuration paired with a high-efficiency vacuum venting system.

In a conventional PET sheet extrusion line, raw PET pellets must be dried to a moisture content below 50 ppm before entering the extruder. PET is hygroscopic; residual moisture causes hydrolysis during melt processing, leading to chain scission, reduced intrinsic viscosity (IV), loss of mechanical properties, and visible defects such as bubbles or haze in the finished sheet. The dryer-free approach eliminates this bottleneck entirely. By the time molten PET reaches the venting zone of the twin-screw extruder, vacuum extraction pulls water vapor and low-molecular-weight volatiles out of the melt stream in seconds—achieving what a desiccant dryer takes hours to accomplish.

The engineering implications are compelling:

Available in three configurations—a multi-layer co-extrusion model (CX85/40&36/40~1000), a single-layer model (CX75/40-1000), and a high-efficiency high-output model (CX95/40-1500)—the CX Series delivers 450 kg/h to 800 kg/h of finished PET sheet with thicknesses from 0.15 mm to 1.5 mm. The line is engineered for 24/7 continuous operation and serves thermoforming converters worldwide who produce food packaging trays, cosmetic containers, medical device blisters, and industrial retail packaging.

This product line complements our broader APET PETG CPET sheet extrusion line offerings and shares core extrusion technologies with our SBP series sheet line and SPC four-roll floor production line, all built on Chenxing's decades-long expertise in screw design, temperature control, and downstream handling.

Complete Production Line Layout

The CX Series PET sheet extrusion line is a fully integrated turnkey system. Every functional module—from raw material intake to finished sheet winding—is engineered for seamless interoperability, modular maintenance, and future upgradeability.

Twin-Screw Extrusion & Vacuum Venting Unit

At the heart of the line sits the co-rotating twin-screw extruder. Screw diameters of Φ75, Φ85, or Φ95 mm combined with an L/D ratio of approximately 40:1 provide the residence time and shear intensity needed to melt PET uniformly without thermal degradation. The screw geometry is purpose-designed with distinct functional zones:

• Feed Zone: PET pellets enter via a screw feeder / automatic feeding machine or forced-side-feeding hopper. Granular material is conveyed forward by intermeshing screw flights.

• Melting & Compression Zone: Barrel heating (electric resistance) and screw-induced shear raise the material temperature above PET's melting point (~260°C). Co-rotating intermeshing screws ensure distributive and dispersive mixing.

• Venting / Devolatilization Zone: A mid-barrel vacuum port connected to a liquid-ring or rotary-vane vacuum pump extracts moisture, glycol, acetaldehyde, and residual oligomers from the melt. This is the critical "dryer-free" step—replacing the entire upstream drying train.

• Metering & Homogenization Zone: Melt is homogenized and pressure-stabilized before discharge.

Each barrel segment features independent PID-controlled electric heating bands and water-cooling circuits. Closed-loop melt thermocouples feed back to the PLC, maintaining temperature uniformity across the entire melt stream. A melt pump (gear pump) downstream further damps pressure pulsations and ensures precise volumetric delivery to the T-die.

Multi-layer co-extrusion configurations (CX85/40&36/40~1000) deploy a secondary co-extruder (45 kW, Φ36 mm screw) that feeds a barrier, tie, or recycled-content layer into a feedblock upstream of the die.

Three-Roll Calendering & Cooling Section

Molten PET exits the T-die as a continuous web and immediately enters a three-roll vertical or inclined calender stack. The rolls are precision-ground, hard-chrome-plated steel cylinders with internal counter-flow water cooling. Critical functions include:

• Gauging: The nip gap between rolls determines final sheet thickness (0.15–1.5 mm), maintained via servo-hydraulic positioning with micron-level accuracy.

• Surface Finishing: Mirror-polished roll surfaces transfer a high-gloss or matte finish to both sheet faces, essential for transparent food-grade packaging.

• Initial Cooling: Rapid surface quenching sets the amorphous or semi-crystalline morphology appropriate to PET, preventing crystallization haze.

Post-calender, a multi-stage cooling conveyor—combining forced-air and water-cooled roller segments—brings the sheet to handling temperature gradually. Controlled cooling prevents warpage, internal stress, and dimensional drift. Auxiliary temperature control is supported by an optional SML air-cooled chiller / industrial chiller or SML water-cooled chiller.

Haul-Off, Winding & PLC Control

After cooling, the sheet enters a multi-nip haul-off unit with synchronized servo-driven rollers. Speed coordination between the calender, haul-off, and winder is maintained by closed-loop tension control, preventing wrinkles and thickness variation.

At the end of the line, an automatic turret winder or a guillotine cross-cutter produces either continuous master rolls (for downstream inline thermoforming) or cut-to-size flat sheets. For operations that also process post-industrial trim or edge scrap back into feedstock, integration with a plastic crusher or plastic grinding machine creates a closed-loop material flow.

The entire line is orchestrated by a Siemens or Mitsubishi PLC with a color touchscreen HMI. Operators set recipe-based parameters (barrel zone temperatures, screw RPM, melt pump speed, line speed, roll gap), monitor real-time trends, and receive automatic fault diagnostics. The system supports OPC-UA / MES integration for smart-factory data acquisition. A green-painted safety guardrail with stair-access platforms surrounds the elevated sections, and the base frame incorporates heavy-duty steel construction with vibration-damping mounts.

Note on rPET Integration: For converters aiming to meet sustainability targets, the CX85 co-extrusion model can sandwich up to 60% post-consumer rPET in the core layer, achieving both regulatory compliance (EU Regulation 2022/1616, FDA 21 CFR) and cost reduction. Vacuum venting in all three models mitigates the moisture variability inherent in recycled feedstocks. For rPET flake pre-processing, we recommend pairing the line with a plastic pelletizer for size reduction and a ZSQ vibrating screen for fines removal.

Key Features

1. Dryer-Free Technology — Eliminate Pre-Drying Entirely

This is the defining innovation of the CX Series. Traditional PET extrusion mandates a dehumidifying drying system—typically a desiccant-wheel dryer paired with a crystallizer—that conditions raw pellets for 4 to 6 hours at 160–180°C before they can enter the extruder. This adds capital expenditure, floor space, maintenance overhead, and continuous energy draw for both heating and desiccant regeneration.

The CX Series sidesteps this entirely: co-rotating twin screws convey PET through progressive heating and compression zones; by the time the melt reaches the mid-barrel vent port, it is fully plasticized. A vacuum pump (typically achieving -0.08 MPa to -0.095 MPa) extracts water vapor, residual glycol, acetaldehyde, and low-molecular-weight oligomers directly from the melt phase. The result is a melt stream with moisture content equivalent to or lower than that achieved by conventional drying—achieved in seconds rather than hours.

Quantified benefits: Energy savings exceed 30% compared to lines with separate dryers. Capital cost avoidance eliminates the crystallizer, desiccant dryer, drying hopper, and associated conveying system. Factory floor footprint shrinks by approximately 15–20 m². Start-up time from cold machine to production drops from 5–6 hours to under 1 hour.

2. Vacuum Venting System — Maximize Sheet Clarity and Mechanical Integrity

The multi-stage vacuum venting zone is not merely an auxiliary feature; it is the quality gate of the entire line. As PET undergoes melt-phase processing, trace moisture, glycol (a PET degradation byproduct), and acetaldehyde can form micro-bubbles, haze, and yellowing in the finished sheet. The vented barrel design—with vacuum applied at the precisely calculated decompression zone of the screw—creates a low-pressure environment where these volatiles flash off before the melt passes into the metering section.

Consequences for the end product: optical clarity suitable for transparent packaging applications; intrinsic viscosity (IV) retention above 0.70 dL/g, preserving drop-impact resistance and thermoforming draw depth; reduced acetaldehyde levels critical for taste-sensitive food-contact applications (bottled water, fruit juices); elimination of "fish-eye" defects and gel formations that plague non-vented PET sheet.

3. Co-Rotating Twin-Screw Plastification — Gentle Shear, Superior Homogeneity

Unlike single-screw extruders that rely on barrel-wall drag for melting, the intermeshing co-rotating twin-screw design provides distributive and dispersive mixing with controlled shear intensity. PET is a shear-sensitive polymer; excessive shear generates localized hot spots that accelerate thermal degradation. The CX Series screw geometry—with optimized flight clearances, kneading block placement, and reverse-element positioning—balances melting efficiency against shear history.

The twin-screw architecture also enables broad feedstock flexibility. The line processes virgin bottle-grade PET, post-industrial rPET regrind, post-consumer rPET flake (washed), PETG, and CPET without screw or barrel changes. For operations that blend recycled content, a disc plastic pulverizer / SMP pulverizer or SMF pulverizer upstream ensures consistent particle size distribution fed into the extruder.

4. Independent Multi-Zone PID Temperature Control

Each barrel segment—typically 8 to 12 zones depending on extruder length—is equipped with a dedicated ceramic-band or cast-aluminum heater, a water-cooling circuit, and a thermocouple feeding into the PLC. PID algorithms adjust heating and cooling actuation independently per zone, maintaining set-point temperature within ±1°C. This granularity is essential for PET because:

• Over-temperature in any zone can trigger thermal degradation (yellowing, IV drop).

• Under-temperature causes incomplete melting, leading to gel specks and thickness variation.

• Precise profiling across the feed → compression → venting → metering zones optimizes material transition through each functional stage.

The die body and die lips are independently heated as well, ensuring uniform melt distribution across the full sheet width.

5. Three-Roll Calendering — Micron-Level Gauge Control

The calender stack is the final shaping stage where melt becomes sheet. CX Series lines employ a vertical or 45° inclined three-roll configuration. Rolls are manufactured from forged alloy steel, internally rifled for turbulent-flow water cooling, hard-chrome-plated, and super-finished to a mirror surface (Ra ≤ 0.025 μm). Roll temperature is independently controlled via external TCU or chiller circuits.

Servo-hydraulic or electro-mechanical roll-gap actuators maintain nip clearance to within ±5 μm across the sheet width. This translates to end-product thickness tolerances of ±0.01 mm—critical for downstream thermoforming where inconsistent gauge causes thin spots, webbing, and part rejection. The mirror roll surface transfers directly to the sheet, producing a Class-A glossy finish without post-polishing.

6. High Throughput for 24/7 Continuous Operation

The CX95/40-1500 high-efficiency model delivers up to 800 kg/h of finished PET sheet. For a typical fruit-tray thermoforming operation consuming ~15 kg/h per cavity set, this one line supplies over 50 forming stations in parallel. The line is engineered for non-stop production: automatic screen changers (optional) enable filter changes without interrupting melt flow; automatic turret winders enable roll changeover at full line speed; PLC-based predictive maintenance alerts notify operators before component wear causes downtime.

For mid-volume operations, the CX75/40-1000 (450 kg/h) and CX85 co-ex line (500 kg/h) provide right-sized throughput with full dryer-free capability.

7. Modular Architecture — Built for Adaptability

Every functional module—feeding, extrusion, calendering, cooling, haul-off, winding—is mechanically independent and electrically interfaced via industrial communication buses (Profinet / EtherCAT). This modularity yields three operational advantages:

• Fast Maintenance: A faulty cooling-roll drive can be swapped without dismantling upstream or downstream sections.

• Field Upgrades: A single-layer line can be retrofitted with a co-extruder and feedblock months after initial installation.

• Quick Product Changeover: Recipe-based parameter sets stored in the PLC recall barrel temperatures, roll gaps, and line speeds for a given product SKU within minutes.

  
  

8. Energy-Efficient and Environmentally Compliant

Beyond the 30%+ energy reduction from eliminating pre-drying, the CX Series incorporates additional eco-design features: high-efficiency IE3/IE4 motors across all drives; regenerative braking on the haul-off and winder sections recapturing kinetic energy; insulation jackets on barrel heaters reducing convective heat loss; and an optional volatile organic compound (VOC) capture manifold at the vent port that routes exhaust to a thermal oxidizer or activated-carbon filter. These measures align with tightening environmental regulations in the EU, North America, and Southeast Asia.

9. Customizable to Your Production Needs

No two converter operations are identical. Chenxing configures each CX Series line to match:

• Sheet width (up to 1500 mm standard; wider on request)

• Number of layers (1 or 3; up to 5 layers available with additional co-extruders)

• Automation level (basic PLC to full MES/SCADA integration)

How It Works — Dryer-Free Vented PET Sheet Process

The CX Series transforms raw PET pellets into finished sheet in eight sequential stages. Each stage is monitored by the central PLC and can be adjusted independently.

Step 1 — Raw Material Feeding
Virgin PET pellets, rPET flake, or a blend is loaded into a floor-level hopper. A screw feeder / automatic feeding machine conveys material at a controlled rate into the extruder's feed throat. Optional loss-in-weight gravimetric dosing ensures blend ratios are maintained within ±0.5%.

Step 2 — Twin-Screw Melting & Plastification
Material enters the feed zone of the co-rotating twin-screw extruder at ambient temperature. As screws rotate at 200–600 RPM, intermeshing flights convey material forward through progressively tighter compression zones. Barrel heaters raise the material temperature above 260°C. The combination of conductive heating and viscous shear dissipation fully plasticizes the PET within the first two-thirds of barrel length.

Step 3 — Vacuum Devolatilization (Dryer-Free Core)
At the mid-barrel decompression zone—where screw channel depth increases to reduce melt pressure—a vacuum port opens to a pump system maintaining -0.08 to -0.095 MPa. Water vapor, glycol, acetaldehyde, and oligomers flash out of the low-pressure melt surface. This step is functionally equivalent to 4–6 hours of desiccant drying, compressed into the melt residence time of approximately 1–2 minutes.

Step 4 — Melt Metering & Homogenization
Post-venting, the melt passes through a final mixing and compression zone where any remaining striations are homogenized. The melt pump (gear pump) at the extruder discharge provides positive-displacement volumetric delivery to the T-die, decoupling die pressure from screw-speed fluctuations and ensuring sheet-weight consistency.

Step 5 — T-Die Extrusion
The homogenized melt enters a coat-hanger or fishtail T-die, which distributes flow laterally across the full sheet width. Adjustable die lips (manual or automatic thermal-bolt systems) permit fine-tuning of transverse thickness profile.

Step 6 — Three-Roll Calendering
The molten web drops vertically or tangentially into the roll nip of the three-roll calender stack. The rolls compress the melt to target thickness, impart the desired surface finish, and begin rapid surface cooling. Roll temperatures—typically 40–70°C for APET sheet—are regulated to prevent crystallization haze while providing sufficient rigidity for downstream handling.

Step 7 — Cooling & Thermal Conditioning
The sheet traverses a multi-stage cooling section comprising temperature-controlled rollers and forced-air cooling fans. Gradual temperature reduction—from approximately 200°C exiting the calender to below 50°C at the haul-off—prevents internal stresses, warpage, and dimensional instability.

Step 8 — Haul-Off, Winding & Cutting
Servo-driven haul-off rolls pull the sheet at a precisely synchronized line speed. At the line end, an automatic turret winder produces rolls up to 1200 mm diameter, or a cross-cut guillotine shears the sheet into flat panels. The finished product is ready for direct feeding into inline thermoforming machines or for shipment to off-site converters.

Frequently Asked Questions

Q1: How does the dryer-free technology actually work? Isn't PET moisture-sensitive?

Yes, PET is highly hygroscopic and will hydrolyze if processed with moisture present. The dryer-free technology does not ignore moisture—it handles it differently. Instead of removing moisture from cold pellets in a separate drying step, the CX Series removes moisture from molten PET inside the extruder barrel at the venting zone. Co-rotating twin screws convey PET through heating and compression until it is fully plasticized. At the mid-barrel decompression zone, the melt pressure drops, and a vacuum pump (achieving -0.08 to -0.095 MPa) extracts water vapor, glycol, and other volatiles from the melt surface. Because mass transfer from a low-viscosity melt is orders of magnitude faster than from solid pellets, the venting step achieves equivalent or superior dehumidification in roughly 1–2 minutes versus 4–6 hours in a desiccant dryer. The resulting IV retention and sheet clarity are fully comparable to conventionally dried PET processing.

Q2: What is the maximum percentage of post-consumer rPET that the CX Series can process?

On the single-layer models (CX75/40-1000 and CX95/40-1500), we recommend up to 30% post-consumer rPET flake blended with virgin PET, provided the flake has been washed, dried, and ground to a consistent particle size (≤10 mm). Beyond 30%, variability in IV, contamination, and melt-flow stability may affect sheet quality. On the CX85/40&36/40~1000 co-extrusion model, the ABA configuration can incorporate up to 60% rPET in the core (B) layer, with virgin PET forming the food-contact skin (A) layers. This approach achieves high recycled content without compromising regulatory compliance or optical properties.

Q3: How does the CX Series compare with a conventional single-screw PET sheet line in terms of energy consumption?

A conventional single-screw PET line with desiccant drying typically consumes 0.38–0.45 kWh per kilogram of finished sheet, with the dryer alone accounting for 0.10–0.15 kWh/kg. The CX Series dryer-free twin-screw line reduces total specific energy consumption to approximately 0.26–0.31 kWh/kg—a reduction of roughly 30%. For a mid-volume plant producing 3,000 tonnes of PET sheet annually, this translates to approximately 300,000–400,000 kWh saved per year, or USD 30,000–50,000 in electricity cost reduction (at industrial rates), plus the avoided capital and maintenance cost of the drying equipment.

Q4: Can the CX Series produce PET sheet for direct food contact applications?

Yes. All three CX Series models are engineered to produce food-contact-compliant PET sheet. The vacuum venting reduces acetaldehyde to levels below sensory thresholds, and the extruder barrel, melt pump, screen changer, T-die, and calender rolls are manufactured from stainless steel (contact surfaces) with food-grade lubricants where applicable. Sheet produced on CX Series lines has been tested by third-party laboratories for overall migration (EU 10/2011) and specific migration limits, meeting requirements for all food types except retort applications. For converters requiring a formal Declaration of Compliance (DoC), Chenxing provides full material traceability and migration test reports.

Q5: What infrastructure is required to install a CX Series PET sheet extrusion line?

A typical CX75/40-1000 installation requires approximately 28 m × 8 m of floor space (machine plus operator/service clearance). The line requires a three-phase 380V/50Hz power supply (other voltages/frequencies configurable), with total installed power of approximately 180–250 kVA depending on model and auxiliary equipment. Compressed air at 0.6–0.8 MPa for pneumatic actuators, and cooling water at 20–25°C with a flow rate of 15–25 m³/h (closed-loop chiller recommended). Floor load-bearing capacity should exceed 5 tonnes/m² to support the extruder and calender stack. Chenxing provides detailed foundation drawings and utility connection diagrams during the pre-installation phase.

Q6: What is the typical lead time and what support is provided after delivery?

Standard lead time for CX Series PET sheet lines is 90–120 days from order confirmation to ex-works delivery, depending on configuration complexity. Installation and commissioning on-site typically requires 10–14 days with a Chenxing engineering team. Our warranty covers 12 months from commissioning or 18 months from shipment (whichever occurs first) for all mechanical components, and 6 months for electrical/electronic components. After warranty, we offer annual maintenance contracts, remote technical support via video call, and a comprehensive spare-parts inventory in Zhangjiagang with DHL/FedEx global shipping.
