Sandwich Panel Machine For Construction

The sandwich panel machine for construction is a highly automated industrial system designed for continuous production of high-quality composite panels. Sandwich panel plant for construction usually adopts modular design, which can be flexibly configured according to different production needs, achieving full process automation control from raw material preparation to finished product cutting.

The core production process includes: metal coil unwinding → surface pretreatment → forming → foaming/bonding → composite → fixed length cutting → stacking and packaging. The advanced sandwich panel production line can reach a speed of 10-15 meters per minute, producing over 5000 square meters of finished panels per day, greatly improving the production efficiency of building enclosure systems.

Core components of sandwich panel production machines for construction

• Metal panel forming system
  Metal panel processing is the first key process in sandwich panel production. Modern uncoiler adopts a hydraulic expansion shaft design, equipped with automatic centering device and tension control system, which can process color coated steel plates, aluminum magnesium manganese plates or stainless steel coils with a thickness of 0.3-1.2mm. The forming unit adopts a multi pass progressive rolling process, which gradually shapes the flat metal coil into the desired plate profile through 12-24 sets of precision rollers.

• Core material processing unit
  The polyurethane (PU) foaming system is the core of polyurethane sandwich panel production, consisting of a precise high-pressure foaming machine, temperature control system, and two-component mixing head. The advanced foaming equipment adopts reaction injection molding technology, with a mixing accuracy of ± 1%, and the foaming density can be accurately adjusted within the range of 30-60kg/m ³.
  For inorganic core materials such as rock wool and glass wool, the equipment is equipped with an automatic feeding system, precise gluing device, and high-pressure composite unit.

• Composite and post-processing technology
  The composite section adopts a multi roll pressure system, with a pressure of 0.3-0.8MPa, ensuring a firm bond between the panel and the core material. The temperature control system maintains a constant temperature in the composite area (usually 40-60 ℃) to promote sufficient curing or complete foaming reaction of the adhesive. The online thickness detector monitors the deviation of finished product thickness in real time, with an accuracy of ± 0.2mm.
  The fixed length cutting adopts a hydraulic or servo driven flying saw system, with a cutting accuracy of ± 1mm and a saw blade life of up to 80000 to 100000 cuts. The stacker crane is equipped with automatic counting and layering devices, with a maximum stacking height of up to 2 meters, and can automatically sort according to order requirements.

The following key parameters should be considered when selecting a sandwich panel production line for construction:

• Production speed: 6-15 meters per minute (depending on configuration)
  

• Applicable plate thickness: 40-200mm
  

• Board width: standard 1000-1200mm, special up to 1600mm
  

• Installed power: 150-400kW (whole line)
  

• Compressed air consumption: 1.5-3m ³/min
  

• Equipment size: length 60-120 meters, width 4-6 meters

Daily maintenance of sandwich panel manufacturing machines for construction:

• Check the oil level at each lubrication point daily
  

• Clean the residue on the roller surface every week
  

• Monthly verification of measurement system accuracy
  

• Check the wear of the transmission system every quarter

Key points for safe operation of sandwich panel making machines for construction:

• Explosion proof electrical configuration is required in the foaming area
  

• Set grating protection in the cutting area
  

• Clear warning signs for high-temperature areas
  

• An emergency stop device is installed every 20 meters

The continuous sandwich panel line for construction has achieved the production goals of high quality, high efficiency, and low energy consumption through technological innovation, providing high-quality enclosure system solutions for green buildings. With the deepening development of intelligent manufacturing, future devices will become more intelligent and flexible, further meeting the personalized customization needs of the construction industry.
