PU Sandwich Panel Line rock wool Panel with cooling system production line
PU sandwich panel line is an automatic production line,which is consisting of decoiler,film coating,pre-cutting equipment,roll forming machine system,preheating,foaming,solidification,band saw cuttinig,cooling,stacking and packiang.The whole line integtates technologies of mechanics,chemistry,eletrical control,hydraulic pressure pneumatic and temperature control.
Main Features of PU Sandwich Panel Machine:
1. The Packaged Equipment is used for discontinuous production of
PU-laminated sandwich panels with color-steel or galvanized
facings. Refer to the panel form drawings for details of panel
form. The maximum length of panel that can be made is 6,000 mm
while the thickness is ranging from 50 to 200mm. With a
transitional padding plate, panels of 20 mm in thickness can also
be produced. The equipment can also be utilized to make sandwich
panels of other forms as long as the forming machine gets changed.;
2. The packaged equipment is made up of two decoilers, two forming
machines, two cross-cutters, two sets of membrane-compounding
mechanisms, one multiple-layer laminator, one reaction injection
machine of low pressure and roller conveyors;
