Automotive electronics pressure sensor dispensing: UV-curing structural adhesive case study

Background

An equipment integrator / manufacturer in Automotive electronics needed to dispensing on a pressure sensor using UV-curing structural adhesive.

Process challenge

High fluid viscosity and resistance causing pneumatic extrusion to lose speed.

Solution

We recommended Pneumatic Valve + Glue Supply System, with replacing time-pressure control with a positive-displacement screw valve to meter by volume.

Result

Volume repeatability improved from ±5% to within ±2%.
Shot volume 0.1 mL with deviation within ±3%.
Cycle time 0.6 s per dot with no stringing or dripping during continuous running.
