PU Insulated Panel Manufacturing Line
The PU Insulated Panel Manufacturing Line is mainly used to produce polyurethane foam boards. It can produce polyurethane fireproof insulation boards with various surface materials, such as aluminum plates, color steel plates, non-woven fabrics, kraft paper or aluminum foil.
Polyurethane insulation board is mainly used for external insulation of building exterior walls, central air conditioning supply ducts, steel structure wall panels, and roof panels. Its excellent insulation and fire resistance make it an important material in the construction industry.
The working principle of the PU Insulated Panel Manufacturing Line mainly involves the following steps:
Raw material ratio and mixing: Polyurethane resin raw materials, curing agents, foaming agents, etc. are transported to the high-speed mixing head by a specific ratio through a metering pump of the infusion machine for uniform mixing.
Fabric and foam: The mixed raw materials are continuously coated onto the upper and lower base materials through the reciprocating motion of the fabric head. Subsequently, the surface material enters the double belt machine and is foamed and solidified between the heated upper and lower layers of the track board.
Trimming and cutting: After the sandwich panel is solidified and formed, it is processed through trimming devices on both sides of the production line to obtain accurate width dimensions. Finally, cut the product according to the set length using a fixed length tracking saw cutting machine.
The continuous production line of composite polyurethane insulation board mainly consists of the following equipment:
Uncoiler: used for unwinding raw materials.
Roll forming machine: performs preliminary forming treatment on raw materials.
Preheating roller conveyor: Preheat the lower substrate to achieve optimal conditions for polyurethane foaming.
Foaming machine: Inject uniformly mixed polyurethane raw materials into the mold for foaming.
Fabric machine: responsible for evenly coating raw materials onto the base surface material.
Double track machine: provides an environment for foaming and curing.
Cut to length cutting machine: Cut the sheet according to the set length.
Roller conveyor: used for conveying sheet materials.
In addition, depending on the different configurations of the PU Insulated Panel Manufacturing Line, it may also include equipment such as laminating machines, trimming machines, and disc board line giant automatic tracking cutting machines.
