The main components of a low-noise pu sandwich panel production line

• Raw material pretreatment system
  Automatic batching unit: adopts precision measuring device, with error controlled within ± 0.5%
  Polyurethane raw material constant temperature storage tank: keep the raw materials at the optimal reaction temperature (20-25 ℃)
  Metal panel pretreatment line: including cleaning, passivation, drying and other processes

• Core production equipment
  Double track continuous foaming machine: equipped with variable frequency speed regulation, noise level below 75 decibels
  High pressure mixing head system: adopting hydraulic servo control, the mixing efficiency is increased by 30%
  Intelligent temperature controlled foam tunnel: temperature control accuracy ± 1 ℃

• Noise reduction design features
  Fully enclosed production cabin: using composite sound insulation materials, the noise reduction effect reaches 25 decibels
  Vibration isolation foundation: effective isolation of equipment vibration conduction
  Low noise fan system: specially designed vortex fan, reducing operating noise by 40%

Technological innovation points

• Silent hydraulic system: using a silent hydraulic pump, the working noise is only 62 decibels
  

• Intelligent soundproof duct: airflow channel design optimized through acoustic simulation
  

• Modular soundproof cover: a detachable soundproof component that is easy to maintain
  

• Night mode: It can automatically switch to ultra quiet operation mode at night

Production process flow

• Panel pretreatment: metal panel cleaning → surface treatment → preheating (60-80 ℃)
  

• Raw material mixing: High pressure mixing of polyol and isocyanate (pressure 150-200 bar)
  

• Continuous foaming: foam forming is completed between double tracks (adjustable speed of 3-8m/min)
  

• Maturation and shaping: Complete the final curing under controlled temperature conditions
  

• Fixed length cutting: servo controlled flying saw system with an accuracy of ± 1mm
  

• Finished product stacking: Automatic palletizing robot completes packaging
