A complete polyurethane sandwich panel production machine typically includes the following key components:

• Uncoiling system: used to unfold metal coils (color steel plates, stainless steel plates, etc.), equipped with automatic correction devices to ensure that the materials enter the production line smoothly;
  

• Forming unit: Process flat metal into the desired concave convex structure through multiple rolling processes to enhance the mechanical strength of the sheet metal;
  

• Foaming system: composed of high-pressure foaming machine, mixing head, and temperature control device, precisely controlling the ratio and reaction conditions of polyurethane raw materials (isocyanates and polyols);
  

• Composite section: Inject liquid polyurethane between two layers of metal panels and foam them under specific temperature and pressure to form a sturdy sandwich structure
  

• Double track laminating machine: provide constant pressure and temperature environment to ensure that foam is fully foamed and tightly bonded with the panel;
  

• Fixed length cutting system: using hydraulic or servo drive to achieve precise length cutting of sheet metal;
  

• Stacking device: Automatically stacking finished boards to improve packaging efficiency.

The continuous polyurethane sandwich panel production line integrates multiple advanced technologies:

• Automation control system: PLC and touch screen human-machine interface achieve full process monitoring, and parameters can be accurately adjusted;
  

• Energy saving design: Heat recovery system reduces energy consumption, foam formula optimization reduces raw material waste;
  

• High precision measurement: using gear pumps or servo measurement systems, mixed proportion error control;
  

• Flexible configuration: By changing the mold, different thicknesses and widths of sheets can be produced.

The pu sandwich panel machine can not only produce traditional building panels, but also manufacture:

• Flame retardant board;
  

• Specialized boards for medical cleanrooms;
  

• Ultra low temperature insulation board for cold chain logistics;
  

• Lightweight soundproof panels are used in ship cabins.

Sinowa is a polyurethane sandwich panel machine manufacturer in china, provide customization and design services, in the field of industrial construction, polyurethane sandwich panels produced by machines have become the preferred choice for large factories and logistics warehouses due to their excellent load-bearing capacity and fast installation characteristics.
