High-speed Sandwich Panel Machine

The high-speed sandwich panel machine is an automated production line equipment specifically designed for producing sandwich panels for construction. It can composite two layers of metal panels (usually color steel plates, stainless steel plates, or aluminum plates) with intermediate insulation materials (such as polyurethane, rock wool, polystyrene, etc.) in a continuous production process. This type of equipment is known for its high efficiency, high precision, and high degree of automation, and has become an indispensable production equipment in the modern construction industry.

Main components and functions of high-speed sandwich panel machine

• Open book system
  Dual station unwinding machine: realizing non-stop roll changing to ensure production continuity
  Automatic centering device: ensures precise positioning of the coil when it enters the production line
  Shear welding machine: Connect the front and rear rolls to avoid production interruption

• Panel pre-processing system
  Cleaning device: Remove oil stains and impurities from the surface of metal panels
  Drying system: Ensure that the surface of the panel is completely dry
  Glue application system: Apply adhesive evenly on the inside of the panel

• Core Forming System
  Foam machine (PU sandwich panel): precise control of polyurethane raw material mixing ratio and injection amount
  Rock wool/glass wool laying system: automatic metering and laying of insulation materials
  Composite press: firmly bond the materials of each layer under high pressure and high temperature

• Forming and sizing system
  Continuous compression molding machine: ensuring the flatness and uniform thickness of the sheet metal
  High speed flying saw: completes precise cutting in continuous movement of sheet metal
  Automatic stacker crane: Automatically stack finished products according to the set quantity

• Intelligent control system
  PLC central control system: coordinate the operation of various components
  Human Machine Interface (HMI): Intuitively display production parameters and status
  Quality inspection system: Real time monitoring of key indicators such as board thickness and flatness

Technical features and advantages

• Efficient production: The maximum speed can reach 15-20 meters per minute, and the daily output can reach 8000-12000 square meters
  

• Precise control: Thickness tolerance can be controlled within ± 0.2mm
  

• Multi functional compatibility: The same production line can produce sandwich panels with multiple core materials
  

• Energy saving and environmental protection: adopting a heat recovery system to reduce energy consumption
  

• High degree of automation: achieving fully automated production from raw materials to finished products
  

• Flexible configuration: Different widths (600-1200mm) and thicknesses (30-200mm) of boards can be customized according to customer needs
