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.

 

If PUR (Polyurethane) and PIR (Polysocyanate) are preferred, heat resistance is higher and there is no flame walking feature and it goes out. The smoke surface it emits is minimal. N-Pentane blowing gas is preferred.

It has the feature of sticking in the foaming stage. Although PUR is less stable than PIR, it has superior thermal insulation feature. Sandwich Panel Production Line can be positioned as I Type and J Type.The production capacity of the line is mostly related to the Press length. For this reason, Sandwich Panel Production Lines are called according to their Press Lengths.

Uncoiler and Coil Car 


a.Up & down-lift are achieved by the use of a hydraulic cylinder which moves right and left supported by 4 wheels by 4 wheels on a rail.

b.Two units are needed for Upper Coil and Lower Coil operation.

c.The steel sheet(coil) is mounted on an uncoiler by the coil car at which point 4 wedges are expanded, and then 4 wedges are expanded, fixed by hydraulic power, and then driven by a motor.

Roll Forming Machine


a.The upper roll forming unit is primarily responsible for shaping the forms of both sides   of the lower coil (steel sheet) for the use of roof & wall (incl. Inner) panels’ joint parts.

b.The Lower roll forming unit forms, Roof 4 rib and SS (Cold room) panel

c.Type for installation are moveable rail type

d.Roll driving is gear box type.

Foaming system 


Pre Heating,Foaming Machine, 

Foaming Portal and PU Pouring :The oscillating movement of the mixing head is essential to achieve an optimum application of the PUR-mixture onto the lower facing layer.

Heating system for double conveyor:PU foam dispensed between the upper and lower coil has the perfect chemical reaction and curing process at regular temperature.

Cooling conveyor


When customer want to produce PIR panel, this cooling conveyor is necessary to cool   down the heat of PU panel.In the production of PIR panel, which is produced a lot recently, as it reacts at higher temperature and generates more heat than general PU panel, cooling conveyor to cool the panel just produced down gradually at room temperature is needed.


Stacker :


This process is designed to stack finished panels efficiently at the production speed. It is very important that the stacking speed should not be slower than panel production speed.
