The SPC Floor Production Line is designed for continuous production of stone plastic composite flooring for residential, commercial and other interior applications. The complete line integrates extrusion, five-roll calendering, online lamination, cooling, UV coating, fixed-length cutting and stacking to provide an efficient SPC flooring manufacturing process.
The line supports SPC floor thicknesses of 2–8 mm and sheet widths of 1050 mm or 1350 mm, depending on the selected extrusion configuration. Production capacity can reach approximately 15–65 tons per day, depending on the extruder model, product specifications and operating conditions.

The SPC flooring production process combines extrusion, calendering, surface lamination and finishing operations into one continuous production system.
Raw Material Preparation → Extrusion → Die Forming → Five-Roll Calendering → Online Lamination → Cooling → UV Coating → Fixed-Length Cutting → Slotting → Automatic Stacking → Packaging
PVC resin, calcium carbonate, stabilizers and other formulation components are prepared according to the required SPC flooring formulation. Proper material preparation helps maintain stable extrusion and consistent floor quality.
The prepared material is processed through a twin screw extruder to produce the SPC substrate. The extrusion system provides controlled plasticization and continuous material output before the sheet enters the calendering section.
The molten SPC material passes through the extrusion die to form a continuous sheet with the required width and thickness.
The five-roll calendering system forms and laminates the flooring structure. The first three rollers are heated for thermal bonding, while the following rollers provide cooling and embossing functions.
The system allows the color film and wear-resistant layer to be laminated to the SPC substrate without using adhesive.
The color film and wear-resistant layer are laminated online during the calendering process. The large laminating roller provides a larger contact area between the layers, helping improve bonding performance.
The downstream rollers are water-cooled to help stabilize the embossing pattern. A silicone roller is used to create deeper and more realistic surface textures.
The flooring surface can be treated with UV coating to improve surface protection and make routine cleaning and maintenance easier.
After surface treatment, the continuous flooring sheet is cut to the required length. Automatic stacking equipment collects the finished products for subsequent slotting, packaging and storage.
The five-roll calendering system is one of the key components of the SPC Floor Production Line.
Compared with a conventional four-roll configuration, the five-roll design combines heating, lamination, cooling and embossing functions in a continuous process. This configuration helps improve production efficiency and the bonding between the SPC substrate, color film and wear-resistant layer.
An SPC Floor Production Line is a complete manufacturing system used to produce stone plastic composite flooring. It combines extrusion, calendering, lamination, cooling, surface treatment, cutting and stacking processes.
The reference product range on this page is 2–8 mm, depending on the selected configuration and production requirements.
The listed reference sheet widths are 1050 mm and 1350 mm. The final width depends on the selected equipment and die configuration.
Reference capacities range from approximately 15 to 65 tons per day, depending on the extruder model and production conditions.
The described five-roll system uses heat pressing to laminate the color film and wear-resistant layer to the SPC substrate, so adhesive is not required for this online lamination process.
Yes. The five-roll calendering system includes an embossing function, and the silicone roller can be used to create deeper and more realistic surface textures.
Yes. Equipment configuration can be selected according to floor thickness, width, capacity, surface structure and finishing requirements.
