Automotive electronics harness connector potting: silicone sealant case study

Background

An equipment integrator / manufacturer in Automotive electronics needed to potting on a harness connector using silicone sealant.

Process challenge

Large potting volume where voiding and incomplete fill are hard to balance.

Solution

We recommended Pneumatic Valve + Glue Supply System, with using a servo dispensing module with a programmable speed profile to hold a constant extrusion rate.

Result

Material utilisation improved by about 8% with visibly less waste.
Shot volume 0.1 mL with deviation within ±3%.
Cycle time 0.3 s per dot with no stringing or dripping during continuous running.
