Advanced Oil Sealing Protection with Cleanliness and ESD Options

In high-precision e-mobility applications, even the smallest contamination can compromise performance and reliability.

This case study shows how a tailored, cleanliness-compliant protection solution was developed to safeguard critical sealing areas of e-Motors and e-Axle systems, ensuring secure handling, clean assembly, and full process integrity from production to final installation.

About Our Partner

A global automotive technology manufacturer operating in a highly regulated environment where component protection, cleanliness, and traceability are essential throughout production and assembly.

Challenges

Contamination & Cleanliness

During the production of e-Motors and e-Axle drive systems, sensitive interfaces required reliable protection against oil, dust, and process contamination. In addition, all components had to comply with strict Cleanliness standards, with ESD protection required for selected applications.

Fit & Sealing Accuracy

Standard off-the-shelf parts did not fully match the counterpart dimensions, which made it difficult to achieve precise sealing and secure positioning. The customer therefore needed customized protection that would fit exactly and remain stable during handling.

Handling & Assembly Safety

The solution also had to stay securely in place during internal logistics and transport, while still allowing for easy and safe removal on the assembly line, without causing damage, contamination, or delays in the assembly process of sensitive interfaces.
