Behind every River Flooring plank is a high-precision manufacturing process. Our automated production line ensures every SPC (Stone Plastic Composite) tile meets international standards for durability, stability, and aesthetics.
| Production Stage | Key Technical Details | Quality Control Standards |
| 1. Raw Material Mixing | High-purity PVC resin combined with premium Calcium Carbonate (CaCO3) and eco-friendly stabilizers. | Precise automated batching to ensure a core density of 2,000+ kg/m³. |
| 2. Extrusion & Calendering | High-temperature extrusion followed by multi-roller calendering to form the rigid core sheets. | Strict thickness tolerance control within ± 0.05 mm for ultimate flatness. |
| 3. Film & Wear Layer | Simultaneous thermal lamination of the high-definition decorative film and 0.3mm/0.5mm wear layer. | Peel strength testing conducted per EN 433 to ensure zero delamination risk. |
| 4. UV Coating | Advanced Double-UV coating technology with a ceramic bead finish for enhanced scratch resistance. | Consistent gloss level monitoring and intensive stain resistance chemical testing. |
| 5. Click-Lock Profiling | Precision profiling using industry-standard Uniclin or Valinge high-speed slotting machines. | 100% inspection of gap & height differences to ensure seamless DIY installation. |
| 6. IXPE/EVA Padding | Automated thermal or adhesive attachment of acoustic underlayment (typically 1.0mm - 2.0mm). | 100% adhesion inspection to guarantee the padding remains securely attached. |
As a leading SPC flooring factory in China, River Flooring welcomes global distributors for factory audits.
The SPC (Stone Plastic Composite) rigid core is a highly stable engineering material primarily composed of natural limestone powder (Calcium Carbonate), high-grade polyvinyl chloride (PVC), and eco-friendly stabilizers. Our production line utilizes a specific, optimized ratio (typically 3:1 limestone to PVC) to ensure the core is 100% waterproof, fire-retardant (Class B1), and provides superior dimensional stability, preventing expansion or contraction even under extreme temperature fluctuations.
Durability is built into our production process through a multi-layered defense system. As shown in our manufacturing video, we apply a high-grade, transparent wear layer (available in 12 mil/0.3mm or 20 mil/0.5mm) followed by a specialized Double-UV coating. This stage is critical for creating a surface that is highly resistant to micro-scratches, stains, and UV fading, ensuring our flooring meets commercial-grade durability standards and heavy-traffic requirements.
