 SPC Floor Advantages


spc floor advantages


  • ECO-friendly

    SPC floor uses calcium powder and PVC as the main raw materials, non-toxic and renewable resources

  • Wear-resistant

    There is a wear-resistant layer on the surface, its wear-resistant revolution can reach 8000-16000 . Ordinary laminate flooring are generally only 1200-9000 revolutions.


  • Waterproof and Damp-proof

    SPC floor produced by the SPC floor machine solves the problem of rotting, swelling and deformation of wood products due to moisture absorption and water absorption in the environment, suitable for any place.

The multi-rip saw is used to cut the SPC large board into several small pieces, and then turn over the board and enter the DET line to do the click profile on the long and short sides. It can be matched with automatic feeding system to reduce labor.


  5. V groove painting line (optional)

    Cut some of the upper edge of the SPC floor at 30/45°, and then paint it. After paving, the seam will show a V-shaped notch. The edge color is rich and layered, and it is more beautiful.


  6. IXPE laminating line (optiaonal)
