Background
An equipment integrator / manufacturer in Optoelectronics and display needed to coating on a LED module using conductive silver adhesive.
Process challenge
High fluid viscosity and resistance causing pneumatic extrusion to lose speed.
Solution
We recommended Dispensing Valve + Glue Distributing Machine, with adding regulated supply with a drum pump for continuous feed to suppress pressure ripple.
Result
- Material utilisation improved by about 8% with visibly less waste.
- Shot volume 0.4 mL with deviation within ±2%.
- Cycle time 1.1 s per dot with no stringing or dripping during continuous running.
Project facts
- Industry: Optoelectronics and display
