Details of PU Sandwich Panel Machine: 

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 of steel 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.

Competitive Advantage: 

Our production system is a fully automation equipment system to produce various shapes of sandwich panels using a rigid-polyurethane foam as a core material which is known as a top insulation in nowadays with low heat conductivity, heat reserving, anti-sweating, high strength durability and availability at construction site.

•    Light weight: 10~ 14 kg/m2 and 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 structures. 
•    Non-water absorbent. 
•    Environmentally friendly. And bring down life cycle cost for any built environment.
