The SPC (Stone Plastic Composite) Floor Production Line is a turnkey extrusion solution for manufacturing high-performance SPC rigid vinyl floorboards. The line converts PVC, calcium powder (stone powder grade), and solvents into stable, waterproof, and dimensionally accurate SPC sheets/boards. Designed for continuous production, the system combines automated metering and high-speed mixing, conical twin-screw extrusion, four-roller calendering, UV tempering, and precision slitting / cutting / packing to deliver finished SPC planks ready for lamination or direct sale.
Core benefits: zero formaldehyde / no glue options, excellent dimensional stability, waterproof and fire-retardant final boards, and flexible downstream finishing.
Product: SPC Floor Production Line (stone-plastic composite flooring)
Key process steps: automatic metering → hot mixing → cold mixing/cooling → twin-screw extrusion → four-roller calender → UV tempering → slitting/cutting → packaging
Typical outputs: rigid SPC sheets / wear-layer laminated boards / click-lock flooring panels
Ideal for: flooring manufacturers producing SPC rigid core boards for commercial and residential flooring
Mixing (Process 1)
Automatic metering by formulation ratio → high-speed hot mixing (hot mixing temp approx. 125 °C) to evenly disperse ingredients and remove moisture → cold mixing to cool blend to ~55 °C and prevent caking/discoloration.
Extrusion (Process 2)
Conical twin-screw extruder for melt/pressure control → sheet die head for extrusion forming → four-roll calender to fix base material thickness → application of color film / wear layer (if required) → cooling → cutting.
UV tempering (Process 3)
Surface UV treatment and tempering with hot water (80–120 °C) and cold water cooling (≈10 °C) to stabilize and harden the surface.
Slitting & packing (Process 4)
Precision cutting, slitting, trimming/chamfering → inspection → packaging and stacking.

(Additional items such as UV units, laminators, wear-layer applicators and packaging stations can be added per specification.)
Health & safety: zero benzene and formaldehyde options; produces glue-free SPC variants; environmentally friendlier production with recyclable outputs.
Stable performance: boards exhibit no cracking, expansion or deformation; low maintenance and long service life.
Waterproof & moisture proof: suitable for environments where traditional wood cannot be used (kitchens, bathrooms, basements).
Fire retardant: achieves fire rating B1 level (subject to formulation and testing).
Pest & bacteria resistance: anti-insect, termite-proof and antibacterial properties possible via formulation.
Acoustic performance: good sound absorption (up to ~20 dB), suitable for hospitals, libraries and offices.
Ease of installation: interlocking click lock or dry-back formats supported.
Aesthetic options: wide choice of wood-grain decorative film and embossing textures for a realistic wood look and tactile surface.
Material inputs: Polyvinyl chloride (virgin, mixed or recycled), stone/calcium powder (stone-grade), solvent (chemical or food-grade solvents as required).
Temperatures: Hot mixing ~125 °C; cold mixing target ~55 °C. UV tempering hot water 80–120 °C; cold water ≈10 °C.
Calendering: Four-roll calender ensures fixed board thickness and high surface quality.
Finish options: Online lamination of color film / wear layers, embossing and UV coating available as add-ons.
Q1 — What SPC board thicknesses and widths can this line produce?
A1 — Thickness and width depend on die and calender tooling. The four-roll calender and T-die allow flexible thickness control; typical SPC boards range from 3 mm up to ~8 mm depending on configuration. Provide target board spec and we will tailor the die and calender.
Q2 — What raw materials and ratios are required?
A2 — The line processes PVC resin (virgin, mixed or recycled), calcium/stone powder and solvent/plasticizer as required by your SPC formula. Automatic metering supports precise batching per your formulation.
Q3 — Can the line produce click-lock SPC with wear layer and decorative film?
A3 — Yes. The extrusion and downstream units support application of color film and wear layer, UV tempering and subsequent cutting to produce laminated SPC planks suitable for click-lock finishing.
Q4 — What level of automation and control is included?
A4 — The system includes automatic metering, automatic feeding and can be supplied with PLC control for process parameters (temperatures, speeds, haul-off synchronization). Options for full PLC/HMI suites are available.
Q5 — What services are provided after purchase?
A5 — We provide installation, commissioning, operator training and technical support. Spare parts and preventative maintenance guidance are also available.
Q6 — How do I size the extruder and line for my desired capacity?
A6 — Capacity depends on target board dimensions and board throughput. Provide your intended production (m²/hr or kg/hr) and board specs and we will recommend extruder size, calendering and downstream tooling.
Q7 — What environmental / safety controls are needed?
A7 — Typical requirements: solvent handling ventilation, solvent recovery (if used), compressed air, adequate power supply and wastewater management for tempering stages. We advise specific local compliance measures during project engineering.
