Medical and consumables IVD reagent cartridge dispensing: instant adhesive case study

Background

An equipment integrator / manufacturer in Medical and consumables needed to dispensing on a IVD reagent cartridge using instant adhesive.

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

• Volume repeatability improved from ±5% to within ±2%.
• 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: IVD reagent cartridge
• Fluid: instant adhesive
• Process: dispensing
• Recommended lines: Screw Valve, Sensor
