HDPE/PP Rigid Plastic Pelletizing Machine
Reliable double-stage extrusion technology for turning HDPE/PP flakes into premium quality, uniform granules.
Designed for Efficiency & Quality
Our granulation line is packed with features to optimize your recycling process.
Smart Ration Feeding
The hopper automatically adjusts feeding speed based on extruder ampere load, preventing overload and Useconsistent throughput.
Double Filtration
Two separate filtration systems—one on the main extruder and one on the secondary—ensure the highest possible purity for your pellets.
Vacuum Degassing
Multiple degassing points, including a specialized "Noodle Outlet" zone, effectively strip humidity and volatile gases.
World-Class Components
Built with reliable electric elements from Schneider, Siemens, and Teco for long-term stability and ease of maintenance.
Processable Materials
Ideal for various rigid plastic forms.
Rigid Plastic Flakes
Pipes & Profiles
Solving Recycling Challenges
We transform common operational headaches into profitable opportunities.
Contaminated Flakes
Recycled rigid plastics often contain impurities that clog screens and degrade pellet quality.
Double Filtration System
By filtering the melt twice (after main screw AND after secondary screw), we guarantee superior purity even with lower-grade inputs.
Bubbles & Moisture
Residual moisture causes foaming and "popcorn" pellets, which are rejected by buyers.
Enhanced Degassing
Our design features vacuum zones and a unique "Noodle Outlet" degassing section to aggressively remove humidity, ensuring solid, dense pellets.
Unstable Output
Manual feeding leads to surging, screw starvation, and varying pellet sizes.
Auto-Ration Feeding
The automated feedback loop between the feeder and extruder motor current ensures the screw is always optimally filled, stabilizing output capacity.
Process Flow
From flake to pellet: a robust double-stage workflow.
Feeding
Screw loader with ration control feeds flakes into the hopper.
Main Extrusion
First stage melting and initial filtration of impurities.
Degassing
Moisture removal via vacuum and noodle outlet zones.
2nd Extrusion
"Baby" extruder provides stable pressure and final fine filtration.
Pelletizing
Water ring cutter and vibration sieve produce uniform, dry granules.
Technical Specifications
Processing PP, PE, ABS, PC, PS flakes and scraps.

Trusted by Recyclers
See what our clients say about the RTM Series.
"The double stage filtration made a huge difference for our contaminated HDPE jerry cans. Extrusion is smooth and the pellets are pure."
"We hit the 650kg/h target easily with the RTM160. The auto-ration feeding really stabilizes the whole line."
"Very impressed with the degeneration capabilities. No more foaming in our pellets, even with wet flakes."
