Medical and consumables microfluidic chip sealing and bonding: filled thermal gel case study

Background

An equipment integrator / manufacturer in Medical and consumables needed to sealing and bonding on a microfluidic chip using filled thermal gel.

Process challenge

Bead width and height must stay stable with no edge creep.

Solution

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

Result

• Overall equipment availability improved by about 12%.
• Shot volume 0.1 mL with deviation within ±2%.
• Cycle time 0.4 s per dot with no stringing or dripping during continuous running.

Project facts

• Industry: Medical and consumables
• Workpiece: microfluidic chip
• Fluid: filled thermal gel
• Process: sealing and bonding
• Recommended lines: Screw Valve, Sensor
