Optoelectronics and display display bezel potting: two-component epoxy case study

Background

An equipment integrator / manufacturer in Optoelectronics and display needed to potting on a display bezel using two-component epoxy.

Process challenge

Particle fillers settling and clogging after long idle periods.

Solution

We recommended Dispensing Valve + Glue Distributing Machine, with adding regulated supply with a drum pump for continuous feed to suppress pressure ripple.

Result

Volume drift held within ±3% over an 8-hour run.
Shot volume 0.4 mL with deviation within ±2%.
Cycle time 0.5 s per dot with no stringing or dripping during continuous running.
