SPC Floor Production Process

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

1. Raw Material Preparation

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.

2. SPC Extrusion

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.

3. Die Forming

The molten SPC material passes through the extrusion die to form a continuous sheet with the required width and thickness.

4. Five-Roll Calendering

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.

5. Online Lamination

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.

6. Cooling and Embossing

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.

7. UV Coating

The flooring surface can be treated with UV coating to improve surface protection and make routine cleaning and maintenance easier.

8. Cutting and Stacking

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.

Five-Roll Calendering System

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.
