Sandwich panels are innovative structural materials consisting of three layers: two outer coatings and internal insulation. They are used in construction to create strong, thermally insulated and lightweight walls, roofs and ceilings. Sandwich panels are used in both industrial and private construction, due to their high stability, strength and energy saving. These properties can be obtained thanks to highly efficient production technology. It will be discussed in our article.

Production Process of Sandwich Panels

The manufacture of sandwich panels is a technologically complex procedure that includes several stages. They can be characterized as follows:

• Preparation of materials. At the first stage, metal sheets or other surfaces are treated, as well as cleaned from dirt. Also at this stage, the insulation is prepared.
• Application of adhesive composition. This stage involves applying an adhesive composition to one of the metal surfaces. In the future, this layer of glue will serve to glue all the layers.
• Application of insulation. Insulation is applied to the adhesive layer. Depending on the type of sandwich panels, polyurethane foam (PU foam), mineral wool or foam can be used for insulation.
• Overlay the second layer. This stage consists in applying a second layer of metal to the insulation, which will become the outer lining of the sandwich panel.
• Pressing and aging. The assembled layers are compressed and subjected to high pressure in a press. The panels are then held at a certain temperature and humidity to completely harden the adhesive composition.
• Cutting and processing. The final stage of production is cutting the formed panels to the desired dimensions and processing them to remove excess materials.

Only a general description of the process is presented here. If you have any questions about the details of the production of sandwich panels, use the help of MaxProduct specialists (the phone number is listed on the website). However, we recommend that you first read the section where you may find the information you are interested in.
