PP Hollow Sheet Extrusion Line – Versatile Manufacturing System for Lightweight Hollow Profile Boards
High-Performance Production Solution for Packaging, Construction, Advertising & Logistics Applications
Our PP Hollow Sheet Extrusion Line is a precision‑engineered manufacturing system designed for the high‑output production of polypropylene (PP) hollow profile sheets – also known as fluted boards, corrugated plastic sheets, or twin‑wall boards. Covering sheet widths from 1100mm up to 2800mm and thicknesses from 2mm to 40mm, this production line is the ideal choice for manufacturers supplying the rapidly growing markets for lightweight, durable, and environmentally friendly material solutions – delivering products used in packaging, construction, advertising, and logistics applications worldwide .
Built as a complete system comprising high‑efficiency single‑screw extrusion equipment, precision vacuum calibration tables, and automated finishing units, this line ensures exceptional product quality, consistent hollow‑cell structure, and reliable continuous operation – providing a complete manufacturing solution from raw material blending to finished sheets ready for fabrication.
Why Choose Our PP Hollow Sheet Extrusion Line?
Advanced Single‑Screw Extrusion Technology
PP hollow sheet production demands specialised processing equipment capable of handling both virgin and recycled polypropylene materials with precision. Our lines feature high‑performance single‑screw extruders (SJ series) with specially designed barrier screws and advanced temperature control systems that ensure excellent plasticisation, high output, and stable extrusion . High‑capacity models deliver outputs of 350–500+ kg/h, maximising production efficiency while maintaining consistent melt quality and pressure stability .Precision Vacuum Calibration & Shaping Systems
Achieving accurate hollow‑cell geometry requires advanced calibration technology. Our lines feature:- High‑power vacuum calibration tables – with independent vacuum subsystems and precise temperature control to ensure uniform sheet flatness within ±0.2mm and consistent hollow‑cell structure
- Multi‑section calibration design – each section with individual vacuum regulation to eliminate deformation and edge collapse
- Specially designed cooling channels – enabling rapid, even cooling without void formation, even for thick sheets up to 40mm
Superior Material Properties & Product Performance
PP hollow sheets produced by our lines offer exceptional performance characteristics that make them the preferred choice across multiple industries:- Lightweight yet high strength – excellent strength‑to‑weight ratio reduces transport and handling costs
- 100% waterproof and moisture‑proof – non‑absorbent, ideal for outdoor and humidity‑sensitive applications
- Impact and puncture resistant – superior durability compared to corrugated cardboard
- Chemical and corrosion resistant – resists a wide range of chemicals, grease, and dirt
- Tear‑resistant and wear‑resistant – long service life with reusability up to 60–150 cycles
- Environmentally friendly – 100% recyclable, non‑toxic, and formaldehyde‑free
- Excellent fabrication properties – can be sawed, drilled, nailed, stapled, scored, creased, folded, heat‑welded, and die‑cut
- Printable and colour‑stable – ideal for high‑quality graphics and advertising applications
Versatile Product Capability
Our line is engineered to produce a comprehensive range of PP hollow sheet configurations, offering manufacturers maximum flexibility to serve diverse market segments:- Single‑wall hollow sheets – standard fluted boards for general applications
- Double‑wall and multi‑wall sheets – enhanced strength with multiple cell layers
- Three‑layer co‑extrusion sheets – core layer with recycled material and surface layers with virgin PP for cost‑effective performance
- Cross‑section designs – I‑type, S‑type, V‑type, X‑type, and custom cell geometries
- Sheet widths – 1220mm, 1400mm, 1800mm, 2100mm, 2400mm, 2600mm, 2800mm
- Sheet thicknesses – 2–6mm, 6–12mm, 12–18mm, up to 40mm with the same die (adjustable range)
Fully Automated Production Control
Integrated with advanced Siemens PLC control systems and intuitive HMI interfaces, the line offers full automation of extrusion parameters including melt temperature, screw speed, vacuum pressure, haul‑off force, and cutting length. The electronic control system optimises the entire line operation, achieving high quality and high output with minimal operator intervention . Real‑time data acquisition, recipe management, and fault diagnostics ensure consistent quality and minimise production downtime.Complete Downstream Finishing Systems
The line includes comprehensive downstream equipment for completing the finished product:- Hydraulic screen changer – ensures continuous operation with quick screen changes
- Melt pump – stabilises melt pressure for consistent sheet thickness
- Vacuum calibration table – precise shaping and sizing with uniform vacuum distribution
- First haul‑off unit – multi‑roller design with wear‑resistant rubber rollers for stable traction
- Oven / Annealing system – removes internal stress to ensure perfectly flat, distortion‑free sheets
- Corona treatment unit – enhances printability for advertising applications
- Cooling table – final cooling before cutting
- Second haul‑off unit – assists in stress removal
- Trimming device – trims edges to precise width with clean, straight cuts
- Automatic cross‑cutting machine – precision cutting to preset lengths
- Discharge / Stacking table – safely collects finished sheets
