Industrial Sandwich Panel Production Machine

Industrial sandwich panel is a type of building panel composed of two layers of metal panels (or other material panels) and an intermediate sandwich material continuously compounded by automation equipment. It is widely used in construction fields such as industrial plants, logistics and warehousing, cold storage, and clean workshops. The sandwich panel production machine is a professional equipment for manufacturing such panels, which achieves high efficiency and high quality panel production through highly automated process flow.

The industrial sandwich panel production machine integrates mechanical, electrical, hydraulic, pneumatic, and computer control technologies, and can produce various specifications and properties of sandwich panels according to different needs, including rock wool sandwich panels, polyurethane sandwich panels, phenolic sandwich panels, and other types.

The main component system of industrial sandwich panel machine

• Open book system
  The unwinding system is the starting part of the production line, responsible for unfolding and preliminary processing of metal coils:
  Dual station unwinding machine: capable of non-stop roll changing and improving production efficiency
  Automatic correction device: Ensure that the material alignment accuracy is within ± 1mm
  Shear welding machine: achieving seamless connection between coils
  Storage rack: provides buffering to ensure continuous production
  Surface cleaning device: removes oil stains and impurities from metal surfaces

• Forming system
  The forming system processes flat metal into the desired shape through multiple rolling processes:
  Upper and lower panel forming machine: using 20-32 rolling processes for progressive forming
  Servo drive system: ensuring molding accuracy and speed stability
  Online size detection: Real time monitoring of panel forming quality
  Quick mold changing device: can complete mold replacement within 30 minutes

• Foam/filling system
  The system configuration varies depending on the type of sandwich material:
  Polyurethane foaming system: including high-pressure foaming machine, mixing head, temperature control system
  Rock wool conveying system: automatic measuring, cutting, and conveying device
  Temperature control system: maintain the optimal performance state of materials

• composite system
  The composite system is the core of the production line, achieving a strong bond between the panel and the core material:
  Double belt press: provides uniform pressure, with a pressure range of 0.3-0.5MPa
  Heating system: infrared or hot air heating, temperature control accuracy ± 2 ℃
  Cooling system: Ensure product shaping quality
  Composite roller group: special surface treatment to prevent material adhesion

• cutting system
  Hydraulic shearing machine: maximum cutting thickness can reach 300mm
  Flying saw cutting machine: cutting accuracy ± 1mm
  Length measurement system: laser ranging, accuracy 0.5mm
  Waste recycling device: automatic collection of scraps

• Stacking and packaging system
  Automatic stacker crane: Stack according to preset program
  Flip device: Achieving alternating stacking of products in both forward and reverse directions
  Film packaging machine: dustproof and moisture-proof packaging
  Labeling system: automatic printing and pasting of product information

Considerations for the selection of sandwich panel manufacturing machines

• Product positioning:
  Determine the main types of sandwich panels produced (PU/PIR/rock wool, etc.)
  Consider product application areas and performance requirements

• Capacity demand:
  Determine production line speed based on market size
  Consider the development needs for the next 3-5 years

• Automation level:
  Balance between labor costs and automation investment
  The demand for automation in quality control

• Space layout:
  Factory length (usually 60-150 meters)
  Equipment occupation and logistics channel planning

• Budget and Investment Return:
  Equipment purchase cost
  Operation and maintenance costs
  Calculation of investment payback period

Industrial sandwich panel production machines are developing towards intelligence, flexibility, and greenness, continuously improving production efficiency, product quality, and environmental performance through technological innovation, meeting the growing demand for high-performance enclosure materials in the construction industry. Choosing suitable production equipment and using and maintaining it reasonably is a key factor for enterprises to improve their market competitiveness.
