The VihoX 105 PP/PS Single-Screw Sheet Extrusion Line is an established, cost-effective industrial workhorse designed specifically for packaging factories producing disposable drinking cups, food bowls, and dairy containers. Featuring a robust Φ105 mm single screw with a 32–35:1 L/D ratio, this line processes standard polypropylene (PP), general-purpose polystyrene (GPPS), high-impact polystyrene (HIPS), and polyethylene (PE) pellets with high melt homogeneity and low energy consumption.
Delivering a consistent output between 150 and 200 kg/h with finished sheet widths from 650 to 850 mm and thickness gauges from 0.3 mm to 2.0 mm, the VihoX 105 features an 800–1000 mm die width and a Φ350 mm three-roller vertical polishing calender. Driven by a dependable chain drive mechanism and powered by a 45–55 kW main motor with approx. 110 kW total installed load, this system offers small-to-medium packaging operations a low initial capital investment coupled with straightforward, low-maintenance daily operation.

Polypropylene requires a gentle, controlled melting curve to avoid thermal degradation, whereas polystyrene demands high shear efficiency to achieve uniform viscosity without overheating. The VihoX 105 screw utilizes a custom-engineered barrier flight profile coupled with a Maddock mixing head. This geometry accelerates melt homogenization, prevents unmelted resin cores from reaching the die, and allows smooth, streak-free color masterbatch blending at ratios up to 4%.
With an installed power rating of only 110 kW and operating consumption hovering around 50 to 65 kW depending on material throughput, the VihoX 105 delivers one of the lowest kWh-per-kg production cost ratios in the B2B packaging sector. The heavy-duty chain drive on the calender stack guarantees synchronized roller rotation with minimal mechanical complexity, enabling factory technicians to perform routine servicing without specialized programming tools.
The 650–850 mm finished roll width makes this extrusion line the standard companion machine for entry-level and expanding cup factories:
Yes. Because PP and PS have different melting points (approx. 190°C–230°C for PP vs 170°C–210°C for PS), the operator simply adjusts the digital temperature controllers on the barrel and die head, followed by a brief purge cycle.
The deep feed flight design of the 105 screw allows up to 30% to 50% clean crushed skeleton regrind to be blended with virgin resin pellets without causing feeding blockages.
The line comes standard with a fast hydraulic plate-type screen changer powered by an independent hydraulic power pack, enabling screen changes in under 3 seconds.
For PS and HIPS, an evaporative cooling tower is often sufficient in moderate climates. For PP extrusion at full 200 kg/h capacity, an industrial water chiller (10 HP) is recommended to maintain crisp roller quenching.
The dual-shaft turret design allows one roll to wind while the operator unloads the finished roll from the alternate shaft. Manual cutting and tape transfer are completed quickly with zero line stoppage.
Standard lead time is 35 to 45 working days. The complete VihoX 105 line packs securely inside one 40-foot High Cube (40HQ) sea container.
The cabinet features high-grade contactors, thermal overload relays, phase-loss monitors, and solid-state relays for PID heating zone temperature stability.
