Consumer electronics TWS earbud housing coating: silicone sealant case study

Background

An equipment integrator / manufacturer in Consumer electronics needed to coating on a TWS earbud housing using silicone sealant.

Process challenge

Tight cycle time with frequent changeovers that squeeze setup time.

Solution

We recommended Screw Valve + Dispensing Valve, with using a high-flow pneumatic valve for staged potting together with vacuum de-airing.

Result

• Volume drift held within ±3% over an 8-hour run.
• Shot volume 0.05 mL with deviation within ±3%.
• Cycle time 0.6 s per dot with no stringing or dripping during continuous running.

Project facts

• Industry: Consumer electronics
• Workpiece: TWS earbud housing
• Fluid: silicone sealant
• Process: coating
• Recommended lines: Screw Valve, Dispensing Valve
