Brief Introduction 

This PU Sandwich panel production line is an automatic production line. In the PU sandwich panel producing procedure, the product line can continuously produce sandwich panel with PU as its core material. The liquid state raw materials were continuously injected into the middle of two steel panels and reacting,foaming,solidifying in the double-rubber belt, the PU sandwich panel could be cut out automatically according to the required length for users.

Detail specification

1. Two sets of uncoiler

It is Automatic and hydraulic, can be used to uncoil steel coil which is maximal 1300mm\'s wide, no more than 5 ton\'s weight and steel coiler\'s inner diameter is about 500mm.

2. Two sets of roll forming machine

Function: Roll forming for the profiles of PU panel

Use the welding H-beam, motor driver, sprocket chain driving

Technical data: Material of roller NO.45forged steel, with digital controlled procession,plated with hard chrome on surface of forming rollers

3. Pu sandwich foaming line

(1) One preheating room: It is built by heat-insulation material, and it could heat up the steel sheet to 25-38

 by heater.  

(2) Two sets of conveyor rack: up conveyor is about 24m, down conveyor is about 30m.They lead the steel sheet from the roll forming machine to preheating room and to foaming,to cutting.

(3) One set of PU two component Liquid mixing and injecting section for foaming : it adopt Chinese high pressure pump. It have the temperature control system and material-level monitoring system. The tank of the material is about 150L. Two tanks. 

Foaming and double rubber device include motor driver system to make panel.

The width of belt board is 1250mm, the range of adjusting distance between upper and lower frame belt board: min 25mm, max 200mm. And the range of adjusting thickness of sandwich panel :30mm,50mm,100mm.(30-50 for celling , 50-100 for wall)

4. Panel automatically cutting system: 

Cutting machine can move 2500mm longitudinally along product line; 

fly saw of the cutting machine can move transversely 1900mm, Cutting machine moves longitudinally and 

transversely along the slide way. 

Cutting machine adopts oneside blade band saw manner, cutting and revolving after cutting. The cutting 

saw can
