A PU (Polyurethane) Sandwich Panel Production Line is a specialized manufacturing system designed to produce sandwich panels, which are composite materials used extensively in construction and industrial applications. These panels typically consist of two outer layers, often made from metal (like aluminum or steel), color-coated steel, non-woven fabric, kraft paper, or aluminum foil, with a core of polyurethane foam that provides insulation, strength, and other properties.

Key Components of a PU Sandwich Panel Line:
- Uncoiling System: For handling and feeding the outer layer materials, such as coils of metal sheets, into the production line.
- Film Covering and Cutting System: Applies protective films on the outer layers if required and cuts them to size.
- Roll Forming Machine:Shapes the metal sheets into the desired profile for the outer layers of the sandwich panel.
- Preheating Oven:Heats the outer layers to prepare them for bonding with the core material.
- High Pressure Foaming System:Injects polyurethane foam into the space between the outer layers under high pressure to ensure even distribution and optimal filling.
- Double Belt Conveyor: Transports the panels through the production process while maintaining flatness and preventing deformation.
- Double Belt Heating Device: Assists in the curing of the polyurethane foam by maintaining the necessary temperature.
- Cutting System:Cuts the finished panels to the specified length after the foaming and curing processes are complete.
- Basic information of PU rolling shutter door machine:
