Stone Plastic Composite Profile Production

This is a technologically advanced ​PVC Stone Plastic Profiles Extrusion Line, specifically engineered for producing high-performance mineral-filled composite profiles. The complete line integrates automatic feeding, high-speed mixing, precision extrusion, vacuum calibration, multi-stage cooling, precise haul-off, and length cutting into a highly efficient automated production system. At its core, the twin-screw extruder​ ensures exceptional homogenization and fusion of PVC resin with mineral fillers such as stone powder. Equipped with an ​intelligent temperature control system​ and ​vacuum calibration table, the production line precisely controls the forming process, guaranteeing outstanding dimensional stability, high density, and refined surface texture of the profiles. The produced stone plastic profiles exhibit excellent properties including ​fire retardancy, moisture and water resistance, impact resistance, and zero formaldehyde emission, making them an ideal eco-friendly altern…
