Background
An equipment integrator / manufacturer in New energy and storage needed to underfill on a battery pack housing using conductive silver adhesive.
Process challenge
Micro-litre volumes with expensive material and no waste allowed.
Solution
We recommended Glue Supply System + Screw Valve + Glue Distributing Machine, with replacing time-pressure control with a positive-displacement screw valve to meter by volume.
Result
- Overflow and stringing defects reduced by roughly 60%.
- Shot volume 0.1 mL with deviation within ±2%.
- Cycle time 0.5 s per dot with no stringing or dripping during continuous running.
Project facts
- Industry: New energy and storage
- Workpiece: battery pack housing
- Fluid: conductive silver adhesive
- Process: underfill
- Recommended lines: Glue Supply System, Screw Valve, Glue Distributing Machine
