Polyurethane Edge Banding Sandwich Panel Machine

The polyurethane edge banding sandwich panel machine is a specialized equipment used for automated production of polyurethane edge banding rock wool/polyurethane sandwich panels.By combining rock wool core material with color steel plate or aluminum plate surface material and using polyurethane material for edge banding, building panels with fire resistance, insulation, and waterproofing properties are formed.

Functions

• Automated Composite: Achieving high-precision lamination bonding between steel plates and rock wool;
  

• Polyurethane edge sealing: edge sealing is achieved through high-pressure foaming technology to enhance overall airtightness and durability;
  

• Thickness adjustment: Supports customized sheet thickness ranging from 10mm to 200mm to meet different building requirements.

Features

• Modular design
  The entire line adopts a modular assembly structure, and each module (such as unwinding machine, foaming system, cold bending forming machine, cutting machine, etc.) can be flexibly combined, compatible with the production of various products such as roof sandwich panels, wall sandwich panels, and cold storage panels. For example, by switching molds, the width of the board (standard board width 1000mm) and the type of core material (polyurethane/PIR/rock wool) can be quickly adjusted.

• Intelligent control system
  Centralized control: All action components are linked and controlled by the main control center, with fault self diagnosis and remote monitoring functions;
  Energy consumption optimization: Adopting a fully enclosed internal insulation design, the energy consumption is only 40% of similar equipment. When the room temperature is above 5 ℃, the temperature should not exceed 1 hour to reach the process temperature.

• Non hydraulic servo technology
  Abandoning traditional hydraulic systems and adopting precision servo lifting mechanisms to adjust plate thickness, avoiding the risk of hydraulic leakage and reducing maintenance costs by over 60%.

• Environmental protection technology
  Use pentane or 141B as the foaming medium.

Configuration of pu edge banding sandwich panel production line
