Project background

Tenghai Nanjing Base encountered technical bottlenecks when undertaking the electric drive shell sealing project of Xpeng Motors in 2025:

  • Conventional 5-gallon rubber pumps exist 5% glue supply pulse, resulting in an average of 32 rubber breaking accidents per month
  • The pressure compensation of the pneumatic system is delayed 0.8 seconds, the thickness of the adhesive layer fluctuates ± 0.25mm
  • The temperature deviation of the heating area of the glue gun is ±8°C, resulting in annual repair losses exceeding the 750,000 yuan

Hongguang system architecture (three-in-one solution)

Patent No.: ZL2025 2 0321548.3 ISO 21987 certification system

(1) HG-5G intelligent rubber pump system

  • Three-plunger staggered compensation technology: < flow fluctuations ±0.3%
  • Intelligent liquid level sensing system: 30 minutes in advance to warn of insufficient glue volume

(2) HG-PRS pneumatic pressure regulator

  • Millisecond pressure compensation: 0.02MPa dynamic balance control
  • Pressure curve self-learning function: supports intelligent switching of 8 pressure modes

(3) HG-MicroHeat Micro Heating Glue Gun

  • Five-zone nano heating technology: gun body temperature gradient <±0.5℃
  • Automatic carbon removal module: reduced carbon deposition rate 90%
