Polyurethane Foam Sandwich Panel Production Line

The Polyurethane Foam Sandwich Panel Production Line is an efficient and automated production equipment specifically designed for producing polyurethane sandwich panels.

The polyurethane foam sandwich panel production line can produce various types of panels, mainly including cold storage panels, wall panels, roof panels, and soft faced coil composite panels. These boards are widely used in the fields of insulation building materials and cold chain building materials, such as refrigerated warehouses, freezers, wall insulation, roof insulation, and various buildings and facilities that require insulation performance.

The main equipment of the polyurethane foam sandwich panel production line includes unwinding system, steel plate feeding system, steel plate automatic docking system, reinforcement unit, forming machine system, high-strength bonding system between steel plate and polyurethane, corona system, steel plate preheating, double track machine and heating system, automatic rock cotton cutting and conveying system, n-pentane foaming system, cutting saw, etc. These equipment work together to complete the whole process from raw material uncoiling, molding, bonding, foaming to cutting and packaging.

In terms of production technology, the two-component raw materials of hard foam are sent to the mixing head by the metering pump of the high-pressure foaming machine at a certain ratio for mixing, then evenly distributed on the bottom surface material of the sandwich panel, and sent to the double track laminating conveyor together with the upper surface material. The hard foam is foamed and solidified between the upper and lower conveyor chain plates of the double crawler laminated conveyor. The cured sandwich panel is cut into finished products of a certain length by a cutting machine on the production line according to production needs.
