Solve Your Most Complex Compounding Challenges
Standard extruders fail when processing complex material blends. Our twin-screw system is engineered specifically for these demanding tasks.
Problem: Inconsistent Mixing
Single-screw extruders struggle to evenly disperse high levels of fillers, fibers, or masterbatch, leading to inconsistent, low-quality products.
Solution: Homogenous Blending
The intense shearing and mixing action of the co-rotating twin screws guarantees a perfectly homogenous melt, even with high additive content.
Problem: Material Degradation
Poor temperature control and localized overheating in standard extruders can degrade heat-sensitive polymers and additives, ruining the batch.
The Advanced Compounding & Pelletizing Process
A systematic process that ensures superior mixing, stable extrusion, and the creation of high-quality, uniform pellets.
1. Precision Feeding
Plastic resin, along with fillers, reinforcing fibers, and other additives, are accurately dosed into the extruder.
2. Intense Mixing & Melting
The co-rotating screws convey, shear, and intensely mix the materials while our stabilization tech ensures a perfect, even melt.
3. Melt Filtration
The homogenous molten plastic is forced through a hydraulic screen changer to remove any contaminants before pelletizing.
4. Pelletizing & Cooling
The clean melt is extruded and cut into uniform pellets using either a strand or water-ring pelletizing system, then rapidly cooled.

Frequently Asked Questions
What is the main advantage of a twin-screw vs. a single-screw extruder?
A twin-screw extruder provides far superior mixing and compounding capabilities. The interlocking, co-rotating screws create intense shearing and distributive mixing, making it essential for blending different materials, like polymers with fillers, fibers, or colorants. A single-screw extruder is better for simple extrusion of a single, pre-compounded material.
What is “Heat Wave Stabilization™” technology?
It is our patented technology that ensures precise and uniform heat distribution throughout the entire extruder barrel. This prevents hot spots and cold spots, which is critical for processing heat-sensitive materials and ensuring a consistent melt viscosity, leading to higher quality and more uniform pellets.
Can this machine be customized for my specific needs?
Yes. The system is highly modular. You can choose different pelletizing methods like “strand pelletizing” or “melt/water-ring pelletizing.” We can also add components like water tanks, dewatering machines, and product silos to create a fully automated production line tailored to your requirements.
