Key Features of Eaststar SPC Stone Plastic Flooring Production Line
Powerful and efficient plasticizing: The core adopts the SZ-65/132 conical twin-screw extruder, with twin screws rotating synchronously in opposite directions. It has forced feeding and self-cleaning functions, which has excellent plasticizing effect on SPC powder formulations and high output efficiency.
Reliable operation : The screw barrel is made of 38CrMoAlA alloy steel and undergoes deep nitriding treatment, resulting in high hardness and extremely strong wear resistance; the gearbox and distribution box gears are made of 20CrMnTi carburizing and grinding process to ensure high torque transmission and low noise operation.
Fully automated control: The entire production line achieves seamless integration from automatic feeding, extrusion, vacuum shaping, traction cutting to unloading. The control system uses international brand components such as Siemens, Omron, and ABB to ensure precise operation and reliable performance.
Exceptional Precision: The 6-meter-long vacuum forming table is equipped with multiple vacuum systems and water cooling to ensure uniform cooling and dimensional stability of the sheet metal. The integrated traction and cutting machine uses dual-track traction and alloy saw blade cutting to guarantee precise product length and clean cuts.
One-stop solution: We not only provide the main extrusion line, but also provide high-efficiency high and low mixing units, precision sanders and high-configuration PUR coating machines, providing customers with a one-stop turnkey project from raw materials to finished flooring.

Frequently Asked Questions
Q1: What is an SPC flooring extrusion production line?
A1: The SPC flooring extrusion production line is the core equipment used for the large-scale production of stone-plastic composite (SPC) flooring. It uses a conical twin-screw extruder to plasticize and compact the stone powder/PVC mixture, form the flooring substrate through a die, and then produce high-quality SPC flooring core boards through cooling, shaping, and cutting processes.
Q2: How does SPC flooring compare to LVT or WPC?
A2: SPC flooring offers enhanced rigidity and stability over LVT and WPC due to its stone-plastic core, making it perfect for high-traffic environments.
Q3: Can the machine produce varying SPC flooring thicknesses?
A3: Yes, the machine supports SPC flooring thicknesses from 3 to 6 mm, customizable to meet diverse market requirements.
