PU Sandwich Panel Production Line

Metal Sheets Mineral Wool PU Sandwich Panel Machine with Auto Stacker

Main Features of sandwich panel production line

• Panel from the continuous sandwich panel production line is a composite structure consisting of two external facings and an insulating core. The core can be flexible with Polyurethane, Mineral Wool, Glass Wool, PIR, Phenolic or EPS. Various profiles are available according to customer's requirement with pre-painted steel sheets, PVC sheets, Aluminum paper or other similar supports;
• The capacity of the continuous line is 4-8m/min, length of the production line is 100m, the size of the final panel is 3-18m long, 900-1200mm wide, 30-150mm thick, the valid length of double belt conveyor is 24m, the total power is 300KW

Technical Data of sandwich panel production line

Panel automatically cutting system
 
1. 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.
2. Cutting machine adopts one-side blade band saw manner, cutting and revolving after cutting. The cutting saw can revolve, so cutting in two directions is realizable.
3. There is panel tight-pressing system (pneumatic) in the cutting machine.
4. There is location limiter to limit longitudinal and transverse motion of cutting machine.
 
 
Three sets of roll forming machine
 
1. Function: Roll forming for the profiles of PU panel
2. Use the welding H-beam, motor driver, sprocket chain driving
3. Technical data: Material of roller NO.45forged steel, with digital controlled procession,plated with hard chrome on surface of forming rollers
 
 
Sandwich foaming line
 
1. 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.
2. One preheating room: It is built by heat-insulation material, and it could heat up the steel sheet to 25-38 by heater.
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.
4. Foaming and double rubber device include motor driver system to make panel.
5. 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)
