The demand for foamed door boards in the U.S. construction sector is surging, driven by the need for lightweight, highly insulative, and water-resistant materials. Our specialized PVC/WPC Foaming Door Board Extruder Lines are engineered to help manufacturers produce high-quality rigid foam panels used for interior and exterior doors, partitions, and cabinetry.Optimized Foaming Process: We utilize either Conical or Parallel Twin Screw Extruders paired with a special foaming T-die and advanced vacuum calibration system. This configuration ensures the foaming agent is evenly dispersed and activated, resulting in a consistent, low-density foam core and smooth, hard surface skin.Precise Density Control: The ability to accurately control the board density is your competitive advantage. Our lines feature highly accurate dosing and feeding systems, allowing you to fine-tune the material composition and expansion ratio to produce boards ranging from low-density Foamed PVC Sheet (suitable for si…
