Automatic Best price Pu sandwich panel forming machine -- Flow chart

1) Rock wool is non-combustible material, so the rock wool panel has good fire resisting proper

The test shows the temperature of the panel fire-proof is as high as 10001°C
2) Roof and Wall panel thickness 100 REI 120
3) Roof and Wall panel thickness 80 REI 60
4) Roof and Wall panel thickness 50 REI 30
5) The roof and wall panels, thickness 50-80-100mm, were classified 0/1 for reaction to fire.

(Materials are assigned a class from 0 to 5, the higher the class, the higher the degree of combustion)
6) Rock wool panel achieves a notable reduction in air borne sound transfer

particularly when specifying a perforated liner.The impact of rain and hail on

the metal sheet, a problem on most standard constructions is greatly reduced

when adopting CX-RW panels.

The CX-RW panel in thicknesses of 50-100mm
with 100kg/m3 rock wool fibre insulation has achieved results of RW=29-30dB 100kg/m3

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.
