PVC Wall/Ceiling Panel Extrusion Line

The line is suitable for producing rigid PVC boards for:
Residential and commercial wall cladding – bathrooms, kitchens, corridors, offices
Ceiling systems – suspended or direct-fixed PVC ceiling panels/strips
Humid environments – thanks to PVC’s excellent water resistance
Fast renovation projects – lightweight, easy-to-install boards
The five models cover the finished board width range:

Real case: A European renovation material supplier installed the 400 YF model (max. width 400 mm, capacity 450 kg/h) to produce large-size waterproof ceiling panels for a hospital project. The line runs continuously for 18 hours per day, achieving 98% dimensional stability with zero water absorption issues.

2.1 High Output and Energy Efficiency
Extruder models – SJZ55/110, SJZ65/132, SJZ80/156 (conical twin screw) provide excellent mixing and plasticizing capacity.
Max. output – from 150 kg/h (YF108) to 450 kg/h (400 YF).
Energy consumption – extruder motor power from 22 kW to 55 kW, achieving low kWh/kg ratio (approx. 0.15-0.12 kWh/kg).
Advantage: Lower energy consumption per ton compared to single-screw or older twin-screw designs.

2.2 Wide and Flexible Width Capability
Single-line widths: 108, 240, 300, 400 mm.
YF240A can produce two 150 mm boards simultaneously – doubling output on common narrow widths without a second extruder.

2.3 Optimized Cooling System
Cooling water flow: 7-8 m³/h (all models).
Sizing tank and spray cooling ensure fast, uniform temperature reduction – critical for preventing warpage and maintaining flatness on wide boards (e.g., 400 mm).

2.4 Robust Design for Continuous Operation
Conical twin screw barrels are hardened and nitrided.
Gearbox and screw design support 24/7 continuous production with minimal downtime.

Each line undergoes strict quality control before shipment, and we recommend customers follow the same process during production.

3.1 In-Process Quality Checks

3.2 Finished Product Testing (one sample per shift)
Dimensional accuracy – width tolerance ±0.5 mm, thickness tolerance ±0.1 mm.
Water absorption – ≤0.5% after 24h immersion (ASTM D570).
Heat deflection temperature – ≥70°C (ISO 75).
Flame retardancy – self-extinguishing (UL94 V-0 or equivalent).

3.3 Production Line Validation Example
A Southeast Asian customer using the YF240 model reported:
*“After 500 hours of operation, we tested 150 random boards. 100% passed width tolerance, and average impact strength was 8.2 kJ/m² – 12% higher than local standards.”*

Q1: What is the actual output when producing a typical 240 mm wall panel (3 mm thickness)?
A: The YF240 (SJZ65/132, 37 kW) achieves 250 kg/h. With board density 1.45 g/cm³, thickness 3 mm, width 240 mm, this equals approximately 240 m²/h – enough to fill a full truckload in one 8-hour shift.

Q2: Can the line produce co-extruded boards (e.g., with a colored cap layer)?
A: Yes. All models can be optionally equipped with a co-extrusion adapter and auxiliary extruder. The main extruder’s output remains unchanged – just account for the additional material flow.

Q3: What water quality is required for cooling?
A: Softened, clean water with pH 6.5-7.5. Hard water (>150 ppm) causes scaling in cooling channels. A closed cooling tower with filtration is recommended. Flow rate must meet specifications (7-8 m³/h) – insufficient flow will cause board warpage.

Q4: How to choose between YF240 and YF240A?
A:
YF240 → single 240 mm board, simpler sizing and haul-off.
YF240A → produces two 150 mm boards simultaneously. Choose this if your market demands narrow boards (150 mm) and you want to double output from a single line. Investment cost is slightly higher due to dual sizing/cutting units.

Q5: Which spare parts should be stocked?
A: Heating rings, thermocouples, screen packs, cutting blades, one set of screw shaft seals. For the SJZ series, we recommend stocking one gearbox oil pump.

Q6: Can the line use recycled PVC?
A: Yes, with proper formulation. Up to 30% clean, dry recycled material (from the same board production) can be mixed with virgin PVC. Higher ratios may affect melt flow and impact strength – we recommend lab testing first.
Customer feedback (Poland, 400 YF user):
*“We replaced our old 300 mm line with the 400 YF. In the same workshop space, output increased from 300 kg/h to 450 kg/h. The wider boards also reduced our installation time by 30%.”
