sandwich panel production line

    The sandwich panel production line includes complete sets of equipment such as color steel plate unrolling, pressing, feeding (steel plate, polyurethane or rock wool), double track forming, finished product cutting, conveying, stacking, cooling (optional for customers), packaging, etc. It adopts microcomputer fixed-length counting device and new technology of field communication bus to realize continuous automatic control of the whole production line, thus making the production line easy to operate and reliable, which is the ideal equipment for producing polyurethane and rock wool sandwich panels with metal surface.

1. Sandwich Panel Making Machine can product beautiful sandwich panels with high practicality, such as insulation, sound – proofing and flame retardance.
2. Hot air circulation furnace strictly controls pu foaming and solidification temperature in suitable range.
3. Precise measurement, high stability, little dust making of the high pressure foaming system protect worker’s health from harm in producing.
4. The pu sandwich panel making machine using 141B(or cyclopentane), instead of CFC as vesicant, PU foaming treatment becomes an enviroment-friendly production technology.
5.  Special double belt conveyor design ensures flat surface, even thickness and anti-deformation of panels.

The first stage of the production line is the preparation of the core material. The core material is typically made of foam, such as polyurethane or polystyrene, which is cut to the required size and thickness using a cutting machine. The outer layers of the sandwich panel are typically made of steel or aluminum, which are also cut to size using a cutting machine.

The second stage of the production line is the application of the adhesive. The adhesive is typically a two-component polyurethane or epoxy resin that is applied to the core material using a spraying machine. The adhesive is spread evenly over the core material to ensure that it adheres properly to the outer layers.

The third stage of the production line is the joining of the outer layers with the core material. The outer layers are placed on top of the core material, and the sandwich panel is then passed through a set of rollers that apply pressure to the panel. The pressure helps to ensure that the adhesive bonds properly to the outer layers and the core material.

The final stage of the production line is the cutting and shaping of the sandwich panels. The sandwich panels are cut to the required size and shape using a cutting machine. The edges of the panels are then finished to ensure that they are smooth and even.

Conclusion

Sandwich panel production lines are an essential component of the construction industry, producing high-quality sandwich panels in a continuous and efficient manner. By understanding what a sandwich panel production line is and how it works, builders and contractors can make an informed decision about the best method for producing sandwich panels for their construction projects.
