Continuous PU Sandwich Panel Production Line With Automatically Cutting System

Brief introduction of production line

    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 three formed panels and reacting,foaming,solidifying in the double-rubber ,the PU sandwich panel could be cut out automatically according to the required length for users.
    This PU panel line consists of 10 tons automatic de-coiler with loading car, chain driven transmission, roll former, PU forming machine, PU panel conveyor, non-stop cutting device, electric controlling system.

Main technology parameters of production

• Production Material(mm): (0.25-1.0)×L, yield strength≤G300 Colored steel

Description of PU Sandwich foaming line

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