Background
An equipment integrator / manufacturer in Consumer electronics needed to sealing and bonding on a phone mid-frame part using UV-curing structural adhesive.
Process challenge
Very small shot volume with high repeatability demands, plus overflow and stringing risk.
Solution
We recommended Screw Valve + Dispensing Valve, with using a servo dispensing module with a programmable speed profile to hold a constant extrusion rate.
Result
- Overflow and stringing defects reduced by roughly 60%.
- Shot volume 0.008 mL with deviation within ±3%.
- Cycle time 0.9 s per dot with no stringing or dripping during continuous running.
Project facts
- Industry: Consumer electronics
- Workpiece: phone mid-frame part
- Fluid: UV-curing structural adhesive
