Background
An equipment integrator / manufacturer in Optoelectronics and display needed to sealing and bonding on a LED module using polyurethane potting compound.
Process challenge
High fluid viscosity and resistance causing pneumatic extrusion to lose speed.
Solution
We recommended Dispensing Valve + Glue Distributing Machine, with using a precision dispensing valve with suck-back and servo three-axis motion for uniform coating.
Result
- Setup time cut from 40 minutes to under 15 minutes.
- Shot volume 0.02 mL with deviation within ±2%.
- Cycle time 0.5 s per dot with no stringing or dripping during continuous running.
Project facts
- Industry: Optoelectronics and display
- Workpiece: LED module
- Fluid: polyurethane potting compound
- Process: sealing and bonding
- Recommended lines: Dispensing Valve, Glue Distributing Machine
