Transformation of gluing system from Chongqing to Xindingzhou base

08/03/2025

Customer case: Chongqing Zhixin Dingzhou Base × Chongqing Hongguang Electromechanical Equipment Co., Ltd

Intelligent upgrade project of new energy battery pack gluing system

Project background

When the Zhixin Dingzhou base undertakes the CATL Kirin battery module project in 2025, it encounters three major challenges:

  • Traditional gluing equipment pressure fluctuations are caused by itThe thickness deviation of the adhesive layer ± 0.28mm(Exceeding the process standard by 200%)
  • The ambient temperature difference (-20°C~45°C) causes the viscosity of the compound to change50% fluctuation
  • The frequency of manual intervention is reached8 times per hour, the comprehensive efficiency of the equipment is only 63.5%

Hongguang core solution
