EXTRUTEX ATP-S Series Sheet Extruders — Precision Power for PVC Sheet Perfection

Introduction: Precision in Motion

Every great sheet begins as a melt — uniform, pure, and stable.
In the world of PVC sheet extrusion, precision is not a feature; it is the foundation upon which all quality stands.

The EXTRUTEX ATP-S Series, featuring the ATP 90-32S and ATP 114-32S, has been engineered with that single pursuit in mind — perfect melt homogeneity, dimensional stability, and surface quality.
These machines are not ordinary extruders; they are architects of consistency, crafted for manufacturers who demand nothing less than excellence in rigid and foam PVC production.

With decades of extrusion experience behind the EXTRUTEX brand, the ATP-S series embodies the fusion of scientific design and industrial strength — where geometry, thermodynamics, and torque unite to produce the cleanest, most stable sheet extrusion possible.

1. The Engineering Heart: Geometric Screw Innovation

1.1. Special Geometric Screw Design for PVC

The secret of the ATP-S Series lies in its precision-engineered screw geometry, meticulously developed by EXTRUTEX’s research division for UPVC and PVC compounds.
Each flight, channel, and compression zone has been shaped to deliver gradual melting, consistent shear, and controlled pressure buildup.

This design ensures:

• Homogeneous melt across the entire width of the sheet

• Uniform plasticization with no overheating or degradation

• Excellent mixing and dispersion of stabilizers, pigments, and additives

• Minimal gel formation, even at high output speeds

The result? Sheets that are smooth, glossy, dimensionally perfect, and strong — the way professional PVC production should be.

1.2. Bimetallic Barrel and Molybdenum Coating

The barrel and screws are built to endure.
Every EXTRUTEX ATP-S extruder uses bimetallic barrels lined with molybdenum (Mo) coatings, resisting wear from fillers and stabilizers, and corrosion from chlorine-based PVC chemistry.
This ensures longer service life, stable output, and low maintenance, even in 24-hour operations.

2. Model Overview: Tailored for Performance

Both machines are designed to deliver steady output with perfect melt uniformity, meeting the needs of high-volume, precision-oriented PVC sheet production.

3. Melt Mastery: Controlled Plasticization

PVC is a demanding polymer — sensitive to temperature, shear, and residence time.
EXTRUTEX addresses this with a multi-zone temperature control system and the geometric screw’s ability to balance energy input.

The result is a melt that’s:

• Thermally stable

• Evenly homogenized

• Ready for smooth flow through flat dies

This means less yellowing, fewer burn marks, and consistently high surface quality on every sheet.

4. System Integration: From Feed to Finish

4.1. Gravimetric Feeding System

Stable feeding equals stable sheets.
Each ATP-S extruder can integrate with gravimetric or volumetric feeders, ensuring that PVC dry blend or pellet feed remains consistent, regardless of batch density variations.
This eliminates surges and pressure instability during extrusion.

4.2. Degassing and Venting Zones

To eliminate trapped volatiles and moisture, the extruder includes dual venting zones with vacuum ports.
This ensures degassed, bubble-free melt — essential for clear sheets and foam boards alike.

4.3. Precision Heating and Cooling

The barrel zones are individually controlled through PID heating systems and forced-air or oil cooling, allowing perfect control of the melt curve.
Operators can fine-tune each zone to maintain ideal viscosity and pressure for their specific PVC formulation.

5. High-Torque, High-Efficiency Drive System

Behind every EXTRUTEX extruder is a powerhouse of mechanical precision.
The ATP-S series features:

• High-torque gearbox with oil circulation cooling

• AC vector motor for precise speed control

• Vibration-free coupling and rigid alignment

Together, these components ensure silent operation, smooth torque transmission, and maximum mechanical life — turning electrical power into stable, productive motion.

6. Intelligent Control and Automation

The ATP-S extruders are managed by PLC-based intelligent control systems featuring:

• Touchscreen HMI with intuitive interface

• Real-time monitoring of pressure, torque, and temperature

• Automatic synchronization with downstream equipment (calender, take-off, cutter)

• Recipe memory and production data logging

The operator’s job becomes simpler, faster, and safer — no guesswork, no interruptions.

7. Structural Strength and Industrial Stability

Every ATP-S extruder stands on a reinforced stainless-steel frame — vibration-resistant and thermally stable.
Even under full torque and high-speed output, mechanical deformation remains near zero.

This structural integrity not only improves alignment and lifespan but also protects sensitive gearbox and motor components during long-term, high-load operation.

8. Production Versatility

The EXTRUTEX ATP-S series is ideal for a wide range of PVC sheet applications, including:

• Rigid PVC sheets for construction and industrial use

• Foamed PVC boards (Celuka or free foam) for furniture, advertising, and cladding

• Clear and colored PVC sheets for packaging and signage

• Multi-layer or co-extruded PVC panels with optional surface layers

With precise melt control and consistent output, these machines can easily integrate into both single-layer and co-extrusion lines.

9. Economic and Operational Advantages

• Low power consumption thanks to efficient torque transfer and controlled shear

• Reduced maintenance from wear-resistant components

• Minimal scrap generation due to uniform melt and stable sheet output

• Longer service intervals and optimized uptime

• High return on investment, as every kilowatt and every hour delivers productive output

EXTRUTEX doesn’t just build machines — it builds profit into the process.

10. Why Choose EXTRUTEX ATP-S Series?

Because precision isn’t accidental — it’s engineered.

The EXTRUTEX ATP 90-32S and ATP 114-32S stand as hallmarks of what modern PVC extrusion technology can achieve:

• Reliability through mechanical strength and control precision

• Efficiency through intelligent design and energy-conscious operation

• Consistency through advanced screw geometry and thermal balance

• Longevity through corrosion-resistant materials and stable construction

Every sheet produced bears the mark of EXTRUTEX engineering — uniform, glossy, and dimensionally true.

Final Word: The Future of PVC Sheet Extrusion

In every revolution of its screw, the ATP-S Series defines what precision means in extrusion.
It melts, mixes, and shapes PVC into a flawless ribbon of material that cools into perfection — sheet after sheet, hour after hour.

For manufacturers who demand durability, clarity, and consistency, the EXTRUTEX ATP-S Series is more than a machine.
It’s a promise — of precision, performance, and profit, built on geometry, driven by engineering, and perfected in motion.
