New energy and storage battery pack housing underfill: instant adhesive case study

Background

An equipment integrator / manufacturer in New energy and storage needed to underfill on a battery pack housing using instant 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 adding regulated supply with a drum pump for continuous feed to suppress pressure ripple.

Result

Overflow and stringing defects reduced by roughly 60%.
Shot volume 0.02 mL with deviation within ±2%.
Cycle time 0.5 s per dot with no stringing or dripping during continuous running.
