Thanks to advancements in powertrain manufacturing, sealing processes have improved assembly efficiency. Formed-in-place gaskets (FIPG) are replacing traditional mechanical fasteners as they are more cost effective, stronger, and easier to apply. However, adhesive bonding rather than mechanically fastening presents different challenges and requires new protocols.

Lead Sales Engineer Lucas Dillingham has presented “Defining Cleanliness in Powertrain Manufacturing for FIPG Applications,” at several events and automotive factories. BTG Labs works with numerous automotive manufacturers on surface chemical cleanliness and what it means for assembly.

Traditional millipore tests reveal particulate contamination, but on a sealing surface, one must detect chemical contamination. To adhere successfully, surface cleanliness on a chemical level is vital.

A byproduct of automotive manufacturing processes is contaminants that are detrimental to adhesion. Processes entailing unwanted contaminants include:

  • Die-casting
  • Machining
  • Washing
  • Assembly

Cutting fluids can be bad news for adhesion.

Most of these contaminants are unavoidable, but that doesn’t mean they aren’t manageable.

Because of the popularity of this topic, Lucas sat down with the microphone to record a new webinar.

In the webinar, he discusses solutions to detecting and controlling chemical contaminants on surfaces.
