Our system is engineered for superior efficiency, quality, and reliability, ensuring you get the maximum value from your recycled materials and a faster return on your investment.
Superior Pellet Quality
Produces uniform, dense, and thoroughly degassed pellets with excellent melt flow, ideal for injection molding and extrusion.
Automated & Stable Operation
VFD-controlled feeding and smart sensors prevent blockages and ensure consistent throughput, reducing operator workload.
Advanced Two-Stage Filtration
A dual-extruder design with multi-stage filtration removes both coarse and fine contaminants, extending screen life and reducing downtime.
Maximum Degassing Efficiency
An innovative dual-zone vacuum system effectively removes moisture, inks, and volatiles, eliminating bubbles and imperfections in the final pellet.
Streamlined Process: Flakes to Pellets
Our seamless, four-step process guarantees the conversion of low-value plastic waste into a premium manufacturing resource.
Consistent Feeding
Washed flakes are automatically fed into the system via a speed-controlled screw conveyor for stable processing.
Plasticizing & Degassing
Material is melted in the first extruder, while the dual-zone vacuum system powerfully removes moisture and volatiles.
Two-Stage Melt Filtration
Melted plastic is forced through a two-stage hydraulic screen changer in the second extruder to ensure ultimate purity.
Pelletizing & Drying
The pure polymer is cut into uniform pellets by a water-ring pelletizer and instantly dried, ready for immediate sale or use.
Two-Stage vs. Single-Stage Performance
See how our advanced two-stage pelletizer stacks up against conventional single-stage solutions. The difference directly impacts your bottom line.
| Feature | Traditional Single-Stage Pelletizer | Our Advanced Two-Stage Pelletizer |
|---|---|---|
| Degassing Efficiency | Limited; often leaves moisture and volatiles. | Superior; dual-zone vacuum removes >99% of volatiles. |
| Melt Filtration | Basic single screen; frequent clogging and changes. | Advanced; coarse + fine filtration reduces downtime. |
| Final Pellet Quality | Prone to voids, bubbles, and impurities. | Dense, uniform, high-purity pellets for premium applications. |
| Operational Stability | Sensitive to material variations; prone to stops. | Highly stable with automated feeding and controls. |
Precision-Engineered Core Components
Every part is engineered for performance, longevity, and ease of maintenance. Explore the features that set our machine apart.
VFD Screw Conveyor
Provides precise, automated control of the material feed rate, optimizing the extruder's performance and preventing overloads.
Primary Extruder
Dedicated to meticulously melting and homogenizing the plastic flakes while performing initial degassing and coarse filtration.
Secondary Extruder
Further plasticizes the material and uses a high-mesh filter to eliminate fine contaminants, ensuring final pellet purity.
Dual-Zone Vacuum Degassing
This innovative system efficiently removes volatiles, inks, and moisture, crucial for producing high-quality, transparent, or colored pellets.
Water-Ring Pelletizer
A robust and reliable die-face cutting system that transforms the molten plastic into uniform granules with high efficiency.
Centrifugal Drying System
Combines a vibration sieve with a horizontal centrifugal dryer to rapidly remove surface water, preparing pellets for immediate packaging.

Frequently Asked Questions
Get answers to common questions to help you evaluate the right pelletizer for your operation.
This machine is primarily designed for pelletizing washed rigid plastic flakes, including PP (polypropylene) and HDPE (high-density polyethylene). It can also be adapted for other rigid plastics like HIPS and ABS. For heavily contaminated or printed materials, our two-stage system is particularly effective.
A two-stage system offers vastly superior degassing and filtration. The first extruder melts the plastic and removes most volatiles, while the second refines the melt and performs fine filtration. This results in higher quality pellets with fewer impurities and "voids." It also reduces the frequency of filter changes, leading to significantly less downtime and higher operational efficiency.
Yes, we offer comprehensive support services. This includes optional on-site installation, commissioning, and operational training for your team to ensure you can operate the machinery safely and efficiently from day one.
All our new recycling machines come with a 12-month comprehensive warranty, covering parts and manufacturing defects. We also provide lifetime technical support and spare parts services to ensure the long-term performance of your investment.
