Watch our rigid plastic pelletizing line transform scrap flakes into high-quality, uniform pellets, ready for your production line.
Engineered for Crushed Flakes and Regrind
Optimized Force-Feeding System
Engineered for rigid flakes, our vertical force-feeder prevents material bridging and ensures a consistent, high-volume flow for maximum throughput.
Heat Wave Stabilization™
Our proprietary technology guarantees exceptionally uniform heat distribution, gently melting the flakes without degradation to produce consistent, high-quality pellets.
Superior Wear Resistance
Built with gas-nitrided 38CrMoAlA steel, the barrel and screw resist abrasion from rigid plastics, ensuring a long and reliable service life.
From Flakes to Pellets
Our streamlined process ensures maximum efficiency and pellet quality.
Pre-crushed and cleaned plastic flakes are loaded into the hopper. The specialized force-feeder actively pushes the material into the extruder screw, ensuring a stable and continuous supply for high output.
The screw transports, compresses, and melts the plastic. A double-vented degassing zone removes any trapped moisture and volatiles, which is critical for producing high-quality, bubble-free pellets.
The molten plastic passes through a hydraulic screen changer to filter out impurities. It is then extruded through a die head and cut into uniform pellets by a high-speed water-ring or strand pelletizer.

Tailor It To Your Needs
We offer flexibility based on your material and operational preferences.
Water-Ring Pelletizing
Ideal for high-output processing of materials like PP and HDPE. It cuts pellets at the die face for uniform, spherical shapes in a highly automated process.
Strand Pelletizing
A versatile method excellent for engineering plastics like ABS, PS, or glass-filled materials. Strands are cooled in a water bath before being cut into cylindrical pellets.

Frequently Asked Questions
What pre-processing is required for hard plastics?
Yes. For best results, plastics must be pre-processed into clean, dry flakes of a uniform size (<12mm). This involves sorting, crushing, washing, and drying to remove all contaminants.
Can this machine handle mixed rigid plastics?
No. The line is optimized to process one type of plastic at a time (e.g., HDPE or PP). Mixing plastics with different melting points will result in poor-quality pellets, so proper sorting is essential.
How does the machine handle moisture in the flakes?
While input flakes should have under 1% moisture, our extruders feature a double-venting (degassing) system. This actively removes residual moisture and volatiles to prevent porous pellets and ensure a high-quality, smooth finish.
Does the line include a melt filter or screen changer?
Yes, a hydraulic screen changer is a standard and critical component. It filters contaminants from the molten plastic to produce clean pellets and protect the pelletizer blades.
