Medical and consumables swab tube underfill: filled thermal gel case study

Background

An equipment integrator / manufacturer in Medical and consumables needed to underfill on a swab tube using filled thermal gel.

Process challenge

Large potting volume where voiding and incomplete fill are hard to balance.

Solution

We recommended Screw Valve + Sensor, with fitting quick-change interfaces and parameter recipes to shorten setup time.

Result

• Overflow and stringing defects reduced by roughly 60%.
• Shot volume 0.02 mL with deviation within ±2%.
• Cycle time 0.7 s per dot with no stringing or dripping during continuous running.

Project facts

• Industry: Medical and consumables
• Workpiece: swab tube
• Fluid: filled thermal gel
• Process: underfill
• Recommended lines: Screw Valve, Sensor
