Medical and consumables medical catheter underfill: UV-curing structural adhesive case study

Background

An equipment integrator / manufacturer in Medical and consumables needed to underfill on a medical catheter using UV-curing structural adhesive.

Process challenge

Particle fillers settling and clogging after long idle periods.

Solution

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

Result

• Potting void defects reduced from 4% to below 1%.
• Shot volume 0.05 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: medical catheter
• Fluid: UV-curing structural adhesive
• Process: underfill
• Recommended lines: Screw Valve, Sensor
