Fireproof Sandwich Panel Machines

The fireproof sandwich panel machine is an automated production line equipment specifically designed for producing sandwich composite panels with excellent fireproof performance. These panels consist of two layers of metal panels (usually color steel plates, galvanized plates, or stainless steel plates) filled with fireproof materials (such as rock wool, glass wool, or flame-retardant polyurethane) in between. With the continuous improvement of fire safety requirements in the construction industry, fire-resistant sandwich panel production lines have become important equipment in the field of building material manufacturing.

The main equipment components of the fireproof sandwich panel machine

• Uncoiler system
  Fireproof sandwich panel production lines are usually equipped with double unwinding machines, which can simultaneously process the upper and lower layers of metal panels. Modern uncoiler adopts hydraulic or electric drive, equipped with automatic centering device and tension control system to ensure the smoothness and accuracy of the panel unfolding process.

• Panel pre-processing unit
  Including panel cleaning, primer application, and drying system to ensure good adhesion between the metal surface and the core material. The advanced preprocessing line adopts electrostatic precipitator and infrared drying technology to improve processing efficiency and quality.

• Fireproof core material conveying system
  According to the different core materials used (such as rock wool, glass wool, etc.), specialized conveying devices are equipped. Rock wool core materials are usually transported using vacuum adsorption conveying technology to ensure the uniformity of the fluffy material during the conveying process.

• Composite bonding system
  One of the core equipment, using high-temperature and high-pressure composite process:
  Two component polyurethane adhesive automatic proportioning spraying system
  Infrared preheating device improves bonding effect
  High pressure composite roller group ensures a tight bond between the core material and the panel

• Continuous foaming system (for polyurethane fireproof sandwich panels)
  High pressure foaming machine, with a proportioning accuracy of ± 1%
  Temperature control system maintains stable foaming environment
  Automatic flow control system ensures even foaming

• Forming machine and press machine
  The multi pass forming roller group gradually presses the composite board into the desired shape (such as corrugated board, flat board, etc.). The pressure in the high-pressure zone can reach 200-300 tons, ensuring the compactness of the board.

• cutting system
  Hydraulic or servo driven flying saw cutting
  Laser length measurement system, cutting accuracy ± 1mm
  Automatic stacking device improves production efficiency

• control system
  PLC+human-machine interface control system can store multiple production parameter formulas and achieve fully automated production. Some high-end devices are equipped with IoT interfaces, supporting remote monitoring and maintenance.

Core technical characteristics of fireproof sandwich panel machine

• Fireproof performance guarantee technology: Ensure that the fireproof performance of the core material is not affected by high temperatures during the production process through a temperature control system
  

• Intelligent temperature control system: Multi zone temperature control to ensure that different materials are compounded at the optimal temperature
  

• Automatic correction device: ensures alignment accuracy of multi-layer materials within ± 0.5mm
  

• Energy saving design: The heat recovery system can reduce energy consumption by 15-20%
  

• Modular design: can quickly replace molds and process parameters according to product requirements

Production process of fireproof sandwich panel
