Automotive electronics pressure sensor sealing and bonding: silicone sealant case study

Background

An equipment integrator / manufacturer in Automotive electronics needed to sealing and bonding on a pressure sensor using silicone sealant.

Process challenge

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

Solution

We recommended Pneumatic Valve + Glue Supply System, with tuning rotor/stator fit and flow path geometry to the filler particle size.

Result

• Setup time cut from 40 minutes to under 15 minutes.
• Shot volume 0.02 mL with deviation within ±3%.
• Cycle time 0.3 s per dot with no stringing or dripping during continuous running.
