Consumer electronics phone mid-frame part coating: filled thermal gel case study

Background

An equipment integrator / manufacturer in Consumer electronics needed to coating on a phone mid-frame part using filled thermal gel.

Process challenge

Very small shot volume with high repeatability demands, plus overflow and stringing risk.

Solution

We recommended Screw Valve + Dispensing Valve, with pairing a micro screw valve with a level sensor in closed loop for accurate volumetric output.

Result

• Material utilisation improved by about 8% with visibly less waste.
• Shot volume 0.1 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: phone mid-frame part
• Fluid: filled thermal gel
• Process: coating
• Recommended lines: Screw Valve, Dispensing Valve
