Insulated Sandwich Panel Machine

The insulated sandwich panel machine is an automated production equipment system specifically designed for producing insulated sandwich panels for buildings. This machine combines two types of metal panels (usually aluminum zinc coated steel plates or stainless steel plates) with an intermediate insulation core material (such as polyurethane, rock wool, or polystyrene) to form building panels with excellent insulation properties. The continuous insulated sandwich panel production line integrates mechanical, electrical, hydraulic, and computer control technologies, achieving fully automated continuous production from raw materials to finished products.

Main components and functions of insulated sandwich panel line

• Open book system
  Double winding machine design, capable of simultaneously processing upper and lower panel materials
  Automatic correction device ensures material alignment accuracy (± 1mm)
  Hydraulic or pneumatic tensioning system maintains constant tension
  Equipped with a pre-treatment cleaning device to remove surface oil stains and impurities

• Forming system
  Multiple sets of high-precision forming rollers (usually 16-24 sets)
  CNC processed hardened steel rollers with a service life of up to 5 million meters
  Quick replaceable mold system, suitable for different plate types and thicknesses
  Real time thickness monitoring and automatic adjustment function

• Foam/filling system (for PU/PIR sandwich panels)
  High pressure foaming machine (working pressure usually 150-250bar)
  Accurate polyol and isocyanate metering system (proportion error<1%)
  The temperature control system maintains the optimal reaction temperature of the raw materials at 18-25 ℃
  Automatic cleaning function prevents pipeline blockage

• Composite compression system
  Double belt continuous press, pressure range 5-15 tons/square meter
  Heating system (electric heating or thermal oil) promotes rapid solidification
  The speed synchronization control system ensures the flatness of the upper and lower board surfaces

• Cutting system
  Hydraulic or servo driven high-speed flying saw
  Cutting accuracy ± 1mm, angle error<0.5 °
  Automatic stacker crane, with a stacking height of up to 2 meters
  Automatic waste recycling device

Selection and maintenance suggestions for insulated sandwich panel manufacturing machines

• Selection considerations:
  Product positioning (high-end/mid-range/economical)
  Common board types and specifications for the target market
  Local environmental regulations require
  After sales service network coverage

• Daily maintenance points:
  Daily inspection of hydraulic system oil level and pressure
  Lubricate all moving parts weekly
  Monthly calibration of the measurement system
  Quarterly comprehensive maintenance of electrical system

• Common troubleshooting:
  Wave pattern on the board: adjust the gap or tension between the rollers
  Uneven foaming: check the temperature and mixing ratio of the raw materials
  Cutting deviation: calibrate encoder and saw blade position
