Background
An equipment integrator / manufacturer in Optoelectronics and display needed to coating on a lens holder using polyurethane potting compound.
Process challenge
Bead width and height must stay stable with no edge creep.
Solution
We recommended Dispensing Valve + Glue Distributing Machine, with using a servo dispensing module with a programmable speed profile to hold a constant extrusion rate.
Result
- Volume drift held within ±3% over an 8-hour run.
- Shot volume 1.5 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
- Workpiece: lens holder
- Fluid: polyurethane potting compound
