Background
An equipment integrator / manufacturer in Medical and consumables needed to sealing and bonding on a IVD reagent cartridge using polyurethane potting compound.
Process challenge
High fluid viscosity and resistance causing pneumatic extrusion to lose speed.
Solution
We recommended Screw Valve + Sensor, with using a precision dispensing valve with suck-back and servo three-axis motion for uniform coating.
Result
- Setup time cut from 40 minutes to under 15 minutes.
- Shot volume 0.008 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: IVD reagent cartridge
