Product Description
A perfect way to finish off our PE film washing line, our state-of-the-art single-screw extruder offers precision extrusion of the clean PP/PE film resulting in high quality pellets that sell for higher values. This is possible through our patented Heat Wave Stabilization™ technology that efficiently distributes heat evenly throughout the extruder barrel via a centralized temperature control meter and PID temperature control. Super mute blower fans are lined throughout the entire length of the barrel for effective cooling.
Our extruders, designed specifically for use with wet PE film, offer various improvements compared to standard pelletizing equipment you’ll find in the recycling machinery market today. To ensure the utmost reliability, our extruder uses a uniquely designed, high-precision gear box that steadily, yet silently drives the molten place forward. Wether you choose a single-stage or double-stage arrangement, our extruder will come standard with a hydraulic assisted screen change to ensure no interruptions throughout each operating session. Due to the possibility of extra moisture within the recently washed PE film, a pressure release mechanism is implemented to remove excess water vapors generated.
As extruders operate in high-heat, high-pressure environments, our extruder’s barrel and screw shaft is manufactured using a special blend of steel that is strengthened by gas nitriding to increase resistance against corrosion and wear.
Wether you’re a fan of “melt pelleizing” or “strand pelletizing”, we offer both water-ring cutting and pellet granulating as per your needs.

Frequently Asked Questions
What does the single-screw extruder do in a recycling line?
It finishes off the PE film washing line by precision-extruding clean PP/PE film into high-quality pellets that sell for higher values. Our patented Heat Wave Stabilization™ technology distributes heat evenly through the barrel via centralized temperature control and PID regulation, while super-mute blower fans along the barrel provide effective cooling — producing consistent, stable melt for premium granules.
Can the extruder handle wet PE film?
Yes — the extruders are designed specifically for use with wet PE film. Because recently washed film may carry extra moisture, a pressure release mechanism vents off excess water vapor generated during melting, preventing bubbles and defects in the pellets. Still, pre-drying with a screw press or thermal dryer reduces steam load and improves pellet quality and throughput.
Should I choose a single-stage or double-stage arrangement?
Single-stage extrusion suits well-cleaned, pre-dried film and lower budgets; double-stage adds a second screw for extra filtration, degassing, and melt homogeneity — ideal for dirtier or wetter feed. If you are weighing extruder types for your recycling line, our single vs twin-screw pelletizer guide explains which arrangement fits which material and capacity.
What pelletizing options are available?
Whether you prefer water-ring cutting or strand pelletizing, both are offered per your needs. Water-ring cutting suits high output with compact pellet size control; strand pelletizing with a pellet granulator gives uniform cylindrical granules. Both come standard with a hydraulic-assisted screen change so contaminated melt can be filtered with no interruptions throughout each operating session.
Which model matches my output requirement?
The range runs from the SJ-100 (Ø100 mm screw, 45–55 kW, 100–200 kg/h) through the SJ-120 and SJ-150 (up to 300 kg/h), SJ-180 (200–400 kg/h), to the SJ-200 (Ø200 mm, 160–280 kW, 600–800 kg/h). All share a 20/32 L/D ratio, gas-nitrided barrel and screw for corrosion and wear resistance, and hydraulic screen change. Match the model to your washed-film throughput with headroom for peak loads.
What keeps the extruder reliable under high heat and pressure?
The barrel and screw use a special steel blend strengthened by gas nitriding for corrosion and wear resistance, and a uniquely designed high-precision gearbox drives the melt forward steadily and quietly. Routine care includes monitoring barrel temperatures, inspecting the screw for wear, maintaining the hydraulic screen changer, and checking the pressure-release mechanism. A scheduled preventive maintenance program matched to operating hours keeps pellet quality consistent.
