Inside the SPC Flooring Production Line Manufacturing Process: Step-by-Step

1. What is SPC Flooring?

SPC (Stone Plastic Composite) flooring is a rigid core luxury vinyl flooring that combines natural limestone powder, PVC resin, and stabilizers to create an ultra-durable, 100% waterproof flooring solution.

Key Features:

✔ 100% Waterproof – Ideal for kitchens, bathrooms, and basements.

✔ Extremely Durable – Resists scratches, dents, and heavy foot traffic.

✔ Realistic Designs – High-definition printing mimics wood, stone, or tile.

✔ Easy Installation – Click-lock system allows for floating floor installation.

✔ Low Maintenance – Stain-resistant and easy to clean.

✔ Stable & Rigid – Resists expansion/contraction due to temperature changes.

2. Composition of SPC Flooring

Core Layer (SPC Core)

• Limestone (Calcium Carbonate, CaCO₃) – Provides rigidity and stability.

• PVC Resin Powder – Binds materials and ensures flexibility.

• DOTP Plasticizer – Enhances flexibility and durability.

• Stabilizers (Ca/Zn) – Prevents degradation from heat and UV exposure.

• Stearine & PE Wax – Improves smoothness and processing efficiency.

• Carbon Black – Adds color consistency and UV resistance.

Decorative Layer

• High-resolution printed film (wood, stone, or abstract designs).

Wear Layer

• UV-Coated Polymer – Protects against scratches, stains, and fading.

Optional Underlayment

• Attached foam or cork for sound absorption and comfort.

3. SPC Flooring Manufacturing Process

Step 1: Mixing Machine

• The PVC mixer unit is for mixing PVC powder, CaCO3 and other additives. This equipment is widely used in PVC sheet production and profile production.

Step 2: SPC Flooring Extrusion Line

• SPC Floor Sheet Extrusion Line manufactured by HallMark is one of the most important process for whole SPC flooring production line.SPC (stone plastic composite) flooring, also named Rigid vinyl plank, is a new type of environmental protection floor developed based on high technology. The raw materials are natural stone powder and PVC resin powder as well as additives.

Step 3: UV Coating Machine

• UV Coating Machine is used to coat UV paint on the surface of SPC board/PVC marble board/PVC ceiling/PVC doors etc.. It can help to keep the glossy uniform and improve the scratch resistance of the surface.UV coating directly affects the wear resistance and scratch resistance of the SPC flooring products.

Step 4: Cutting and Double end tenoner Line

• This production line is used to cut the SPC floor slab of the extrusion line into several small pieces through multi-blade saws, and then enter the slotting machine to perform button processing on the long and short sides.

Step 5: SPC Floor V Groove Painting Machine

• SPC Floor V groove painting line is used for SPC floor V-shape groove paint .Cut some of the floor upper edge at 30/45°, and then paint it with water-based paint . After paving, the seam will show a V-shaped notch. The edge color is rich and layered, and it is more beautiful.

Step 6: IXPE/EVA Laminating Machine

• Bond the underlayment materials on the backside of the flooring to improve the ability of sound insulation.After adjusting the flooring straight system, the floor go with the conveyor and be coated with glue, go through the heating oven ,laminate the underlayment (IXPE/EVA) tightly by rubber rollers ,then trimming.

Step 7: SPC Floor Packing and Stacking Line

• Packing and Stacking line of packaging machine is a high-speed automatic packaging line, designed and developed for the automatic packaging of standard plastic floors on the market.
