How Twin Screw Extruders Work

1

Material Feeding

Plastic materials are fed into the twin screw barrel through precision gravimetric or volumetric feeders, ensuring consistent flow rates and optimal processing conditions.

2

Co-Rotating Screws Mix & Melt

Two intermeshing screws rotate in the same direction, creating intense shear and distributive mixing. The modular screw design allows customization for specific materials and applications.

3

Compounding & Homogenization

Advanced screw configurations ensure thorough mixing of additives, fillers, and reinforcements, achieving molecular-level homogeneity with precise temperature control throughout multiple barrel zones.

4

Degassing & Purification

Vacuum vents remove moisture, volatiles, and trapped air from the polymer melt, improving final product quality and preventing defects in downstream processes.

5

Die Formation & Pelletizing

The homogeneous melt exits through a strand die or underwater pelletizing system, producing uniform pellets ready for manufacturing or resale.

6

Cooling & Collection

Pellets are rapidly cooled in water baths or air cooling systems, then dried and conveyed to storage silos, maintaining consistent quality throughout the production cycle.

Core Advantages of Our Twin Screw Extruders

Superior Mixing Efficiency

Co-rotating twin screws deliver distributive and dispersive mixing that single-screw extruders cannot match, ideal for complex formulations and recycled materials with contamination.

Flexible Process Control

Modular screw configuration and independent barrel zone temperature control enable processing of diverse materials—from virgin polymers to heavily contaminated post-consumer waste.

Self-Wiping Technology

Intermeshing screw design prevents material buildup and degradation, reducing downtime for cleaning and eliminating cross-contamination between batches.

High Throughput Capacity

Process 200–2,000 kg/hr depending on model, with consistent output quality even at maximum production rates.

Effective Degassing

Multiple vacuum ports efficiently remove moisture and volatiles from recycled plastics, improving pellet quality and downstream processability.

Energy-Efficient Operation

Advanced drive systems and optimized screw geometry reduce specific energy consumption by up to 20% compared to conventional designs.

Turning Plastic Processing Challenges Into Opportunities

Common Industry Challenges

  • Inconsistent melt quality from recycled feedstock with varying contamination levels
  • Poor mixing of additives and fillers leading to product defects and customer complaints
  • Excessive material degradation from prolonged residence time in traditional extruders
  • High moisture content in recycled plastics causing porosity and weak mechanical properties
  • Frequent production stops for screw cleaning and material changeovers
  • Limited flexibility to process different polymer types on the same line

How Our Extruders Solve This

  • Advanced twin-screw mixing technology homogenizes even heavily contaminated recycled materials
  • Distributive and dispersive mixing zones ensure uniform additive distribution throughout the melt
  • Self-wiping screw design and optimized residence time minimize thermal degradation
  • Multi-stage vacuum degassing removes up to 2% moisture without pre-drying, reducing operating costs
  • Quick-change screw modules enable rapid material changeovers in under 30 minutes
  • Versatile barrel and screw configurations process PE, PP, PS, PET, ABS, and specialty polymers

Frequently Asked Questions

What types of plastics can twin screw extruders process?
Our twin screw extruders can process virtually all thermoplastics including PE, PP, PS, PET, PVC, ABS, PA, PC, and specialty polymers. They excel at handling contaminated recycled materials, masterbatch production, and compounding applications with fillers, fibers, and additives. The modular screw design allows customization for specific material characteristics.
What’s the difference between co-rotating and counter-rotating twin screw extruders?
Co-rotating twin screws (where both screws rotate in the same direction) offer superior mixing, self-wiping capability, and shorter residence times—ideal for compounding and recycling. Counter-rotating screws provide higher pressure build-up for profile extrusion and PVC processing. Our standard models feature co-rotating intermeshing screws for optimal performance in plastic recycling applications.
How much moisture can the degassing system remove?
Our multi-stage vacuum degassing system can efficiently remove up to 2% moisture content without pre-drying, and up to 0.5% with standard atmospheric venting. For applications requiring ultra-low moisture (< 0.02%), we recommend combining the extruder's degassing with upstream drying. This significantly reduces energy costs compared to traditional full-capacity dryer systems.
What maintenance is required for twin screw extruders?
Routine maintenance includes daily cleaning of feed throats and die heads, weekly inspection of screw segments for wear, monthly gearbox oil level checks, and quarterly bearing lubrication. The self-wiping screw design dramatically reduces internal cleaning requirements. Screw segments and barrel liners are wear parts that typically last 8,000-12,000 operating hours depending on material abrasiveness.
Can I upgrade my current single screw extrusion line to twin screw?
Yes, twin screw extruders can often integrate with existing downstream equipment like pelletizers, cooling systems, and packaging lines. Our technical team will evaluate your current setup and recommend the optimal twin screw model and necessary modifications. In most cases, upgrading delivers immediate improvements in product quality and production flexibility.
What’s the typical lead time for a twin screw extruder system?
Standard models with common configurations typically ship within 12-16 weeks. Custom configurations with specialized screw designs, additional degassing zones, or integrated feeding systems may require 16-20 weeks. We maintain inventory of critical wear parts and provide comprehensive installation support and operator training.
