Especially in the high-voltage sector, it becomes clear that optimizing individual products or components alone is not sufficient. What is required is a systematic approach. With the iFast Competence Center, ARNOLD UMFORMTECHNIK has created a framework in which all relevant dimensions of electrical contact fasteners are brought together.

At the core are three pillars:

Conductivity: consistently low contact resistance achieved through optimized contact geometries, contact pressure, and surface finishes.

Cleanliness: particle-free connections in accordance with VDA 19.1, validated assembly processes, and testing methods capable of detecting even the smallest disturbances.

Sealing: protection against moisture and media through sealing concepts verified according to IP standards and helium leak testing.

Beneath these pillars lies consolidated engineering expertise – ranging from simulation-based design according to VDI 2230, FEM analyses, and ultrasonic preload force measurements to electrical resistance testing in the micro-ohm range.

This is complemented by system technology for assembly and process monitoring, ensuring reliable implementation in series production.

The focus of the presentation could be on Electrical Contact Fasteners (ECF); please also see the attached abstract. However, this is still under discussion, and both the presentation and the detailed content will need to be further developed.
