The VihoX 120 PP/PS Single-Screw Sheet Extrusion Line is an industrial-scale manufacturing solution engineered for converters requiring heavy hourly throughput to feed high-speed thermoforming machinery. Driven by a powerful 90–132 kW main motor with an installed electrical capacity of 160–190 kW, this extrusion line incorporates a high-efficiency Φ120 mm single screw with a 32–35:1 L/D ratio, delivering stable plasticizing output between 250 and 350 kg/h.
Equipped with an 800–1000 mm precision T-die and an enlarged vertical three-roller calender stack (Φ400–500 mm) driven by independent AC motors, the VihoX 120 achieves line speeds up to 30 m/min while maintaining consistent web cooling across sheet widths of 650 to 850 mm. Its combination of heavy mechanical construction and independent roller drives makes it ideal for high-volume single-layer PP, GPPS, and HIPS packaging production.

Extruding up to 350 kg of polypropylene per hour demands exceptional plasticizing stability. The VihoX 120 features an alloy steel barrel with bimetallic lining and cast aluminum ceramic heating elements controlled by multi-loop PID microprocessors. The deep-channel feed throat incorporates spiral grooved water-cooled sleeves, preventing premature resin bridging when feeding lightweight regrind or high-melt-flow homopolymer PP pellets.
Unlike conventional mechanical chain-driven stacks, the calender rollers on the VihoX 120 are driven by independent AC vector motors coupled to precision planetary reducers. This independent drive architecture allows operators to program minute speed differentials (draw ratio compensation) between the top, middle, and bottom rollers. This capability eliminates surface chatter, optimizes sheet gloss, and prevents internal residual stress that causes cup curling during downstream thermoforming.
The high throughput of the VihoX 120 makes it the primary extrusion engine for scaled packaging operations:
The 120 model increases hourly capacity to 250–350 kg/h (approx. 40% higher than the 110), powered by a 90–132 kW motor and featuring independent roller drives for superior high-speed web control.
Yes. Equipped with a forced feeding hopper and grooved barrel section, the line easily handles up to 50% clean crushed skeleton regrind mixed with virgin pellets.
A heavy-duty hydraulic plate-type screen changer with integrated accumulator ensures instantaneous screen switching in under 2 seconds without stopping line throughput.
We recommend an industrial water chiller rated at 15 to 20 HP (approx. 45,000 to 60,000 kcal/h) to maintain optimal roller temperatures during peak summer production.
Yes. The frame architecture accommodates standard beta-ray, X-ray, or optical inline thickness measurement scanners with feedback loop displays.
The dual-station winder uses magnetic powder brakes or variable-frequency torque motors with ultrasonic roll diameter tracking, ensuring constant tension as roll diameter expands.
A dedicated factory transformer with a rating of ≥ 250 kVA is recommended to support the 160–190 kW installed load with sufficient operating safety margin.
Yes. Our engineering division prepares detailed 2D/3D plant layout drawings, cooling water piping schematics, power distribution diagrams, and compressed air sizing specifications.
