The complete set of equipment for polyurethane sandwich panel production line is mainly composed of uncoiling system, film cutting system, forming machine system, steel plate preheating furnace, high pressure foaming system, double track system, double track heating system, cutting system, horizontal cooling system, palletizing System, packaging system and other series of equipment, the main core equipment part is the molding machine system.

The production process of polyurethane sandwich panel
There are basically two ways to produce polyurethane sandwich panels: continuous production and discontinuous production. At present, the continuous production process is suitable for enterprises with high output requirements, while the discontinuous production process is suitable for products with special shapes that cannot be continuously produced, or the production volume is not enough to invest in continuous equipment.
In the continuous production process, the materials used to make the sandwich panels are processed together at high speed. The polyurethane foam is continuously sprayed between the upper and lower surface materials that have been formed at a constant speed, and there is a polymerization reaction there to produce different forms of Polyurethane sandwich panel. After the sandwich panel is fully formed, the cutting is performed at the expected length, and the production line of the cutting process does not stop.
In the non-continuous process, the materials are processed separately, which means that after the face material is formed, it is cut to the required length, then assembled together into the laminator, and the foam is injected between the face materials to generate a predetermined shape Polyurethane sandwich panel.
