Our three-in-one combined mini pelletizing and mini 3D filament extrusion line offer a flawless solution to your manufacturing requirements. With the capability to seamlessly transition pelleting and filament production, this versatile setup ensures optimal utilization of resources and minimizing operational interruptions.
By sharing common components, such as the 16 mm single screw extruder, water bath/air conveyor and center control systems, cost efficiency is maximized without compromising on quality of both obtained pellets and plastic 3D filaments.
The compact layout of this line guarantees efficient use of space within your facility. Streamlined operation is achieved through ease of switching between the use of water bath and air cooling conveyor, corresponding with either pelletizer unit or winder unit, enabling quick adaptation to changing demands.
Additionally, our combination line offers exceptional material compatibility, accommodating a wide range of materials with diverse properties. Regardless of whether you are producing pellets or 3D filaments, you can trust in our commitment to delivering consistent results and superior performance.

3D Filament Process
When 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, which has an adjustable temperature of up to 85 °C. Upon leaving the water bath, the residual water on the filament surface is eliminated by an air wipe nozzle located at the end of water bath unit to ensure filament is completely dry before passing through pull rolls and a strand guide, and is finally collected at winder.
The air conveyor is designed with a swing mechanism, allowing it to be easily moved 90 °C from its current position to the backside. This adjustment creates additional space for the operations that are focused on using only the water bath.
When working with hydrophilic (water sensitive) materials, an alternative method can be employed that uses an air conveyor in place of a water bath. In this method, the water is drained from the bath, and the filament is initially guided through the now-empty bath. Subsequently, the filament is passed through an air conveyor that is equipped with fan cooling. This approach extends the cooling path of the filament, thereby enhancing the efficiency of the cooling process.
Pellet 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.
The continuous strand is then guided into either a water bath or an air conveyor belt, depending on the material being processed. If the material is hydrophobic, meaning it repels water, the water bath is utilized. Conversely, if the material is hydrophilic, meaning it attracts water, the air conveyor belt is used. The air conveyor belt is specifically designed with Teflon material and is equipped with three fans to facilitate the cooling process.
After passing through water bath and/or air conveyor belt, the polymer strand is cut into uniform 3-mm pellets using a high-speed pelletizer and is then ready for further processing.
This pelletizing line offers a flexibility of using a single screw extruder (16 mm) for standard operation. For the intensive mixing of multiple polymers or incorporating additives, an optional twin-screw extruder (12 mm or 16 mm) can be chosen to ensure optimal material homogenization.
