Consumer electronics TWS earbud housing dispensing: instant adhesive case study

Background

An equipment integrator / manufacturer in Consumer electronics needed to dispensing on a TWS earbud housing using instant adhesive.

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

• Filler-related stoppages reduced from three per week to one per month.
• Shot volume 0.02 mL with deviation within ±3%.
• Cycle time 0.3 s per dot with no stringing or dripping during continuous running.

Project facts

• Industry: Consumer electronics
• Workpiece: TWS earbud housing
• Fluid: instant adhesive
• Process: dispensing
• Recommended lines: Screw Valve, Dispensing Valve
