ISP Machine or ISP (Insulated sandwich panel) production lines produce roofing and wall sandwich panels with thermal materials insulated, like EPS, Rockwool and Polyurethane(PU) etc for cold areas or regions, or for special purposes.
An ISP (insulated sandwich panel) consists of 3 layers (top metal layer, middle thermal material layer (like EPS/XPS board, Rockwool strips, and Polyurethane or PU foam), and bottom metal layer or aluminum foil layer) like a sandwich, so in many occasions it is named as a sandwich panel as well. Through an ISP machine line, or insulated sandwich panel production line, customers is able to make insulated panels or sandwich panels which have been widely applied as roofing, wall panels, decoration exterior or interior wall panels, garage door panels and rolling shutter slats etc.
Insulated sandwich panels have better functions of thermal insulation or heat preservation then single metal roofing or wall cladding sheets, and therefore the isp machine line for insulated sandwich panels are much more complicated and more expensive than roll forming machines.
Take PU insulated metal carving decorative wall panel production line for example. This line consists of 4 or 5 roll forming machines, and furthermore, more than 10 sets of embossing machines are working inline, not saying PU foaming machine and the main laminating eqiupment.
