Yongte PVC foam board extrusion line is a specialized production system designed for manufacturing PVC foam boards, which are lightweight, durable, and versatile materials used in a wide range of applications, including signage, furniture, construction, and more.

Components of PVC crust foam board extrusion line:

Production flow of PVC crust foam board extrusion line:

• Raw Material Handling: loading PVC resin powder, foaming agents, stabilizers, and other additives into a high-speed mixer or blending unit to create a uniform compound.

• Primary Extrusion: The mixed PVC compound is fed into conical double screw extruder with a specific screw design to achieve uniform melting and pressure buildup. The extruder barrel is heated to melt the PVC material effectively.

• Foaming and Expansion: Foaming agents incorporated in the compound expand and create a cellular structure within the material during extrusion, resulting in a lightweight and foamed PVC board.

• Die Head Design: The molten PVC  foam material is pushed through a die head, which imparts the desired thickness, width, and surface texture to the foam board.

• Calibration and Sizing: The extruded foam board passes through a calibration unit to control its dimensions and thickness. Sizing tools and cooling systems help ensure uniformity and consistency.

• Cooling Conveyor: The freshly extruded PVC foam board is transferred to a cooling conveyor to cool, allowing it to retain its final shape.

• Surface Treatment: optional embossing or lamination units to apply textures, patterns, or protective coatings to the surface of the foam board.

• Cutting Machine: Once the PVC foam board is fully cooled and set, it is cut to the desired length and dimensions using a cutting machine.

• Edge Trimming: Edge trimming units may be used to ensure clean and smooth edges on the foam board for a professional appearance.
