Description
Our innovative three-in-one combined mini pelletizing and mini 3D filament extrusion line offers an impeccable solution to your manufacturing needs. Designed for seamless transitions between pelleting and filament production, this versatile setup ensures optimal resource utilization while minimizing operational interruptions.
The line features shared components, including a 16 mm single screw extruder, water bath/air conveyor, and center control systems, maximizing cost efficiency without compromising the quality of both pellets and plastic 3D filaments. Its compact layout guarantees efficient space utilization within your facility. Streamlined operation is achieved through easy switching between the water bath and air cooling conveyor, corresponding with either the pelletizer unit or winder unit, enabling quick adaptation to changing demands.
Our combination line excels in material compatibility, accommodating a wide range of materials with diverse properties. Whether producing pellets or 3D filaments, you can trust our commitment to delivering consistent results and superior performance.

Operating Process:
-
3D Filament Process:
- When the 3D filament process is required, the single screw extruder is connected to a filament die with a precise hole diameter of 1.75 mm or 2.85 mm.
- The melted filament strand exiting from the die is guided into a water bath with an adjustable temperature of up to 85°C, then the residual water on the filament surface is eliminated by an air wipe nozzle to ensure the filament is completely dry before passing through pull rolls and a strand guide, and finally being collected at the winder.
- The air conveyor is designed with a swing mechanism, allowing it to be easily moved 90° from its current position to the backside. This adjustment creates additional space for operations focused on using only the water bath.
- For hydrophilic (water-sensitive) materials, the air conveyor can be employed in place of a water bath, enhancing the cooling process efficiency by extending the cooling path.
-
Pelletizing Process:
- When the demand switches to pelletizing extrusion, the single screw extruder is connected to the strand die, which has a hole diameter of 3 mm.
- Depending on the material being processed, the water bath or an air conveyor belt is used: if the material is hydrophobic (repels water), the water bath is utilized, whereas if the material is hydrophilic (attracts water), the air conveyor belt, specifically designed with Teflon material and equipped with three fans to facilitate the cooling process, is used.
- The melted filament strand exiting from the die is guided into a water bath with an adjustable temperature of up to 85°C. After the water bath, the residual water on the filament surface is eliminated by an air wipe nozzle.
- The continuous strand is then cut into uniform 3-mm pellets using a high-speed pelletizer.
