Conical twin screw extruder ensures efficient material plasticization.
The one-step forming extrusion process enhances production efficiency and product consistency, making it ideal for high-quality decorative marble sheet manufacturing.
Integrated PLC control systems enable real-time monitoring, quick parameter adjustments, and fault diagnostics, reducing downtime and operator dependency for stable, continuous operation.
Midtech’s PVC Artificial Marble Sheet/Wall Panel/Interior Decoration Board Production Line is used to make PVC imitation marble sheet which have marble, carpet, stones, natural scenery, stereo design on the surface. And the board is popular in the hospital, school, office buildings, shopping malls,supermarkets, transportation and other public places.
The production process begins with material preparation using crushers and millers, followed by mixing. The materials are then extruded, laminated, and shaped through calendering. Subsequent steps include cooling, cutting, stacking, and optional UV coating, resulting in the final PVC marble sheet.

Core Advantages
Extruder
World famous brand electrical component such as Siemens, Schneider, WEG,LS etc.
High torque gearbox with adopts NSK/SKF bearing;
Special design of screw screw and barrel suit for high calcium.
Intelligent PLC controlling system with human-friendly interface.
Mould
T type mould Hanger flow passage.
PVC-friendly mold materials reduce wear and sticking, lowering cleaning and repair frequency.
Maintains precise thickness and flatness even under continuous high-speed operation.
Offers excellent thermal stability for long, stable operation.
Three-Roll Polishing Stack
Multiple sets of heat-conducting oil-controlled calendering rolls precisely control.
Enable online embossing and lamination synchronization.
A synchronous control system matches the calender speed with the downstream puller.
Roll gaps can be adjusted electrically or manually. An emergency stop device allows quick stop.
It’s a synthetic decorative panel that mimics natural marble, used for interior wall decoration, flooring, ceilings, and furniture panels. It offers heat insulation, moisture resistance, flame retardancy, and corrosion resistance at a lower cost than real stone.
What are the main components of the production line?
The complete line includes: high-speed mixer & cold mixer → conical twin-screw extruder → T-shaped die → three-roller calender (with lamination station) → cooling rollers → haul-off & trimming unit → shearing/cutting machine → automatic stacker. An optional UV coating line adds gloss and durability.
What extruder models are commonly used?
The two most common conical twin-screw extruders are:
80/156 model – 75kW motor, output ~10 tons/24h
92/188 model – 90kW motor, output ~15 tons/24h
Is the UV-coated surface durable?
Yes. A proper UV coating achieves 3H–4H pencil hardness, resisting scratches from keys, furniture, and regular cleaning without visible marks. It also provides a high-gloss, protective finish.
