The line is a kind of specialized equipment used for producing
color-steel-sided sandwich panels with
the middle layer of anti-combustion polyurethane.
The thickness of the produced sandwich panel ranges from 30 to 150
mm, the width between 700 and 1000 mm and the length on request.
The production line is mainly applied to make wall and roof panels
structure buildings, which can also make various other insulation
panels if replacing facing sheet. Its
operation principle is as follows: Rigid poly foam 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.

To support the finished panels
These sandwich panels are mostly used for industrial purpose, these
are very light weight but can bear
very heavy load. It also reduces the heat inside the building.
With a wide range of different colors, available in cut-to-length
supply and ready-to-install,
this modern building product takes a good share in a highly
economic, weather-independent and fast,
modular building process.
Beside the extremely high thermal-insulation values of the
polyurethane-core,the panels create
a high overall stiffness with their "composite" function and
therefore support very good statically values.
• Light weight: 10~ 14 kg/m2and hence reduced steel frameworks and
system can become economical.
• Good thermal insulation, with average coefficient of thermal
conductivity is 0.018 ~ 0.020 W/mk.
• Available in customized length. And in wide range of colors.
• Cold and heat resistance: Perfect temperature resistance
deformation from -110º C to 120º C.
• Great energy saver and hence indispensable in air-conditioned,
cooled and heated buildings.
• Virtually zero maintenance throughout life.
• Installation is convenient and Flexible; not requiring large-
scale lifting devices, and thus lowering building costs.
• High intensity and large rigidity ensures suitability for
weight-bearing structures and for supporting and protective
• Non-water absorbent.
• Environmentally friendly. And bring down life cycle cost for any
