pu sandwich line Wall panel and Roof panel Sandwich Panel Line


Our company offers professional PU sandwich panel production line. Our PU sandwich panel is characterized by uninflammability, moistureproof capacity, insect-resistance, sound insulation, and light weight. Besides, it is never out of shape whether in dry or wet conditions. It has good heat preservation capacity. This machine can be nailed as well as sawn, which makes construction easy and convenient. This PU sandwich panel can be repeatedly used.
This equipment is widely used for steel structure workshop, roofs of simple and easy movable houses, wall body, suspended ceilings of air purification room, and separation. The rigid polyurethane foam has been recognized as the best building thermal insulation material by international world today. It has low heat conductivity, and high bending resistance capacity. This rigid polyurethane foam doesn’t absorb water or decay, and it cannot be damaged by insects and mice. It has good fire resistance, and large scope of heat resistance. With the physical properties of polyurethane PU and our unique prescription, we combine high temperature polyurethane with coating steel panel, thus compact forming is achieved.
Then rigid colored steel and soft chemical raw materials are combined to cooperate with polyurethane PU foaming forming machine.
The PU panel forming machine mainly includes decoiler, feeding machine, film-covering installation machine, roll forming machine, PU foaming machine & injecting machine PU, laminator, automatic tracking cutter, and PLC control cabinet, etc.

Reference Work Flow:
Decoiling -- roll forming -- PU injecting -- Belt conveyer -- Fly cutting -- product run out


Application:

Roof Wall PU Sandwich Panel, Insulated Sandwich Panel, Prefabricated House, Prefab House, Mobile House, Cool Room, Air conditioner pipe, etc

Seaworthy nude packing, using steel wire and wood bock to fix the machine inside container, and using the film cover the machine for dustproof
