Project background

Zhixin Anhui base will face industry pain points when undertaking the Li Auto new generation battery pack project in 2025:

  • The traditional rubber pump is not continuously supplied 15 times per hour
  • The error of the quantitative machine ± 3% The annual waste of rubber exceeds 800,000 yuan
  • The efficiency of the one-way dispenser limits the cycle time of the production line 42 seconds/piece

Hongguang system architecture (trinity solution)

Patent No.: ZL2025 2 0321548.3 ISO 21987 certification system

(1) HG-55G high-flow rubber pump system

  • Double helix booster design: flow range200-5500mL/minContinuously adjustable
  • Equipped with pressure self-balancing algorithm, the glue supply pressure fluctuates <±0.5%

(2) HG-QM3000 high-precision quantitative machine

  • It adopts mass flowmeter + volumetric dual metering mode, and the accuracy is reached ±0.15%
  • In the tank 32 sets of recipesMemory function, change time < 20 seconds

(3) HG-DH2000 double-pass heating glue gun

  • Dual working mode: forward gluing/reverse gluing, improving efficiency 40%
  • Eight-zone temperature control system: gun body temperature gradient control <±0.3℃
