High-Performance Co-Rotating Twin Screw Extruders
Unlock the full potential of your industrial applications with Rumtoo's twin screw plastic extruders. Our extensive experience and innovative technology provide an all-in-one solution for your compounding and pelletizing needs, offering unparalleled reliability for even the most demanding jobs.
Working Principle
- 1. Material Conveying
Raw materials (polymers, fillers, additives) are fed into the extruder. The co-rotating screws then convey the material forward through the barrel.
- 2. Melting & Mixing
As the material moves, the barrel's heaters and the intense shearing action of the screws melt the polymer. The closely intermeshed screw elements ensure a thorough, homogeneous mixing of all components.
- 3. Extrusion & Pelletizing
The uniformly mixed molten plastic is forced through a die, forming strands. These strands are then cut into pellets by a pelletizer (e.g., water-ring or strand cutter) and cooled.
Advanced Technical Characteristics
- Modular Design
Our screws and barrels are designed on a building block principle, allowing for easy customization, upgrades, and interchangeability.
- Exceptional Power Transmission
A state-of-the-art torque distribution system with high-precision gears, imported bearings, and integrated lubrication enhances durability.
- Heat Wave Stabilization™
This patented technology ensures even heat distribution throughout the barrel, creating an ideal environment for consistent, high-quality plastic pelletizing.
- Innovative Screen Changer
Choose from basket, plate-type, or continuous models to keep your operations running smoothly without interruptions during screen changes.
Versatile Applications
Our twin screw extruders excel in a variety of sectors, engineered to handle materials with fillers, reinforcing fibers, or heat-sensitive additives.
- Plastics & Compounding
- Chemicals & Powder Coatings
- Food Industries
- Wood-Plastic Composites

Frequently Asked Questions
The primary advantage is its excellent mixing and compounding capability. The closely intermeshed, self-wiping screws ensure that materials like fillers, additives, and polymers are blended homogeneously, resulting in a consistent, high-quality final product.
The "building block" principle of our screws and barrels offers incredible flexibility. You can easily change screw elements or barrel sections to adapt the extruder for different materials or processes, without needing to replace the entire machine. This saves both time and money.
Depending on your preference, you can opt for either "melt pelletizing" or "strand pelletizing." We can integrate additional components like a water-ring cutter or a strand pelletizer with a water tank to create a complete, automated production line.
