Product introduction
Complete SPC flooring line for industrial production
Jiahao SPC flooring production line is designed for manufacturers producing rigid stone plastic composite flooring at industrial scale. The line can be configured with 110/220, 115/230, 125/235 and 132 main machine options, combined with auto dosing, hot and cold mixing, conical twin-screw extrusion, sheet die forming, five-roll calendering, cooling, cutting and downstream finishing.
According to the production route, the line can include scrap recycling, SPC board extrusion, 48-hour board curing, UV coating, 24-hour coating curing, slitting and slotting, optional V-bevel painting, IXPE or EVA underlay lamination, automatic packing and finished product storage.
With hourly capacity options from 1,000 to 2,600 kg/h, the line is suitable for buyers planning large-scale SPC flooring manufacturing. Under stable production conditions, one full day of output can support container-level finished flooring shipment planning.
Production process
From auto dosing to finished product packing
The process route follows the full SPC flooring production flow from raw material preparation to extrusion, curing, UV coating, slotting, underlay lamination and packing.
Scrap recycling and auto dosing
Production scrap can be crushed and reused, while the auto dosing system weighs and prepares the raw material formula.
Hot and cold mixing
Hot mixer reference temperature is 125 ℃, followed by cold mixing at 55 ℃ to cool material and prevent agglomeration or color change.
SPC board extrusion
The conical twin-screw extruder, sheet die and five-roll calender form and size the SPC board.
Curing and UV coating
The board is cured for 48 hours, then enters UV coating, followed by a 24-hour curing stage for coating and substrate bonding.
Slitting and slotting
Boards are cut and processed into locking profiles. V-bevel painting can be configured as an optional process.
Underlay lamination and packing
IXPE or EVA underlay can be laminated before automatic packing and finished product storage.
