Consumer electronics phone mid-frame part sealing and bonding: instant adhesive case study

Background

An equipment integrator / manufacturer in Consumer electronics needed to sealing and bonding on a phone mid-frame part using instant adhesive.

Process challenge

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

Solution

We recommended Screw Valve + Dispensing Valve, with tuning rotor/stator fit and flow path geometry to the filler particle size.

Result

• Overflow and stringing defects reduced by roughly 60%.
• Shot volume 1.5 mL with deviation within ±3%.
• Cycle time 0.9 s per dot with no stringing or dripping during continuous running.

Project facts

• Industry: Consumer electronics
• Workpiece: phone mid-frame part
• Fluid: instant adhesive
• Process: sealing and bonding
• Recommended lines: Screw Valve, Dispensing Valve
