Usage :

The discontinuous PU sandwich panel production line is mainly applied to make wall panels of steel structure and roof

panels, being also able to make various other insulation panels if replacing facing sheet.


This production line is used to produce continuously of two-sided sheet, which is a kind of sandwich panel to insert polyurethane or phenolic aldehyde. Its working principle is that the polyurethane or the phenolic aldehyde materials are sent to the mixing machine based on a regular proportioning by the metering pump on the foaming machine. After mixing, the raw material is distributed equably on the bottom board. Then all of them will be sent into the double caterpillar laminated conveyer together with the upper board. The foam will be foaming and curing between two delivery link joints of the double caterpillar laminated conveyer. The laminated board after curing will be cut off by the automatic cutter according to the length needed on the production line.

Operation principle:


Rigid polyfoam raw materials, according to a certain blending ratio, are delivered into mixing head to agitate through

metering pump unit on the injection machine and then uniformly injected onto the bottom facing sheet of sandwich

panel. After the injection the bottom facing sheet shall move toward the double-belt conveyors together with panel's

top facing sheet. Between the two conveyors, injected raw material is foamed and hardened into shape. At the end of

the line, the formed sandwich panel is cut into preset length by an automatic tracking cutter.
