EXTRUTEX WPC Profile & Panel Extruders — Strength in Nature, Precision in Polymer

Introduction: Engineering the Fusion of Wood and Plastic

Wood Plastic Composite extrusion isn’t just a process — it’s an art of balancing opposites. The warmth of natural fiber meets the precision of polymer science, and only a perfectly engineered extruder can harmonize the two.
That’s where EXTRUTEX ATP Series WPC Extruders stand tall — ATP 75-36W, ATP 90-36W, and ATP 114-36W— a family of machines built to master the complexity of WPC profiles and panels with efficiency, consistency, and quiet mechanical power.

With production capacities ranging from 100 kg/h to 450 kg/h, this series transforms raw flour and polymer blends into high-density, low-moisture, dimensionally perfect WPC products ready for decking, wall panels, ceiling tiles, and decorative profiles.

EXTRUTEX has poured decades of twin-screw engineering into these machines — merging metallurgy, motion control, and process intelligence into a single production heart that never misses a beat.

1. Engineered for the Nature of Composites

1.1 Heavy-Duty All-Steel Frame

Each ATP extruder is built upon a fully-welded steel chassis, vibration-isolated and tube-reinforced, capable of bearing the torque of double-screw drives and the thermal dynamics of composite processing.
Rigid. Balanced. Built to run 24/7.

1.2 Twin-Screw Mastery with WPC Geometry

Unlike PVC powder, WPC compounds behave like living matter — variable, fibrous, moisture-sensitive.
EXTRUTEX’s co-rotating parallel twin screws are engineered with deep channel geometry and optimized mixing zones, allowing for gentle yet thorough dispersion of natural fibers. The result? A perfectly homogenized melt that preserves fiber integrity while achieving excellent surface gloss and density.

1.3 Molybdenum & Bimetal Barrel Coatings

To counter the abrasive wood flour and fillers, every screw and barrel is molybdenum-hardened or bimetal-lined, ensuring long life even under continuous high-friction workloads. Wear resistance is not optional — it’s engineered into every micron.

1.4 Modular Temperature Zoning

Each extruder features multiple independently controlled heating and cooling zones, finely tuned to maintain stability through the entire melt path. This ensures consistent plasticization, preventing scorching of natural fibers or polymer degradation.

2. Intelligent Extrusion Efficiency

2.1 Controlled Feeding for Fibrous Blends

The WPC feedstock is complex — a mix of polymer, fiber, pigment, and additives. EXTRUTEX uses precision gravimetric feeders with anti-bridging systems to ensure steady material flow, avoiding clumps or fluctuations that could disrupt melt uniformity.

2.2 Vacuum Degassing for Purity

Integrated twin-stage vacuum vents remove moisture and volatile gases during melting. This critical step ensures that the extruded product is free from bubbles, voids, or surface streaks — especially vital for decking and visible architectural profiles.

2.3 Synchronized Drive Control

With AC vector motors, torque sensors, and frequency-controlled drives, the system synchronizes screw rotation, feeding rate, and downstream calibration automatically. The result is a seamless flow from hopper to haul-off, ensuring constant dimensional accuracy at every speed.

2.4 Energy Optimization

Through high-efficiency motor systems and low-friction mechanical design, the ATP series achieves up to 20% lower power consumption compared to conventional extruders of the same output class.
Less energy, less wear, more profit.

3. Profitability in Every Kilogram

3.1 Consistent Output, Minimal Waste

Each model — from the agile ATP 75-36W (100–200 kg/h) to the powerhouse ATP 114-36W (up to 450 kg/h) — is optimized for high yield and tight process control. The stable melt pressure and consistent feed result in near-zero scrap rates during full-speed operation.

3.2 Maintenance Made Simple

The barrel assembly, gearbox, and cooling circuits are designed for accessibility. With long-life sealing systems and quick-change heating elements, downtime is reduced to an absolute minimum.

3.3 Longevity Through Design

By combining wear-resistant metallurgy, vibration-free construction, and modular system architecture, EXTRUTEX ensures a service life that outlasts market averages — protecting your investment year after year.

4. Tailored Applications for WPC Excellence

• Decking & Flooring Profiles: Dense, smooth, weather-resistant WPC decking with perfect fiber distribution and matte-gloss control.

• Wall & Ceiling Panels: Lightweight hollow or solid boards with uniform wall thickness and minimal warping.

• Decorative Trims & Structural Profiles: Precise extrusion with sharp edges and smooth surface finishing for both indoor and outdoor use.

• Co-Extruded WPC Panels: Compatible with co-extrusion for surface coloring, embossing, or protective skin layers.

Each ATP extruder can be paired with EXTRUTEX downstream calibrators, cooling tables, and haul-offs for a fully integrated WPC extrusion line.

5. Operator-Centric Design

EXTRUTEX doesn’t just engineer machines — it engineers experiences.

• Touchscreen HMI Controls: Centralized control with recipe memory and live monitoring.

• Quick-Access Maintenance Points: Simplified lubrication and screw removal design.

• Full Safety Suite: Overload and torque protection, emergency stop circuits, thermal cut-offs, and fault alarms — all standard, not optional.

6. Why Choose EXTRUTEX ATP-W Series?

Because this isn’t a repurposed PVC extruder — it’s purpose-built for the composite revolution.

• Designed for wood-filled, bamboo-filled, and rice-husk composites.

• Built with advanced thermal and torque control systems.

• Proven to deliver long-term reliability in the world’s most demanding extrusion environments.

From 100 kg/h to 450 kg/h, the ATP series covers the full industrial spectrum — from compact production lines to high-throughput panel systems.

7. Final Word: Turning Raw Nature into Engineered Beauty

The EXTRUTEX ATP-W Series is more than a machine — it’s the heartbeat of modern composite production. It takes the imperfection of raw fibers, tempers it with molten polymer, and gives birth to materials that bridge the organic and the engineered.

For manufacturers seeking durability, precision, and profit — EXTRUTEX ATP 75-36W, 90-36W, and 114-36W are not just extruders.
They are instruments of transformation — where engineering meets nature, and innovation becomes structure.
