A well-known known manufacturer of diesel filters in the heavy-duty truck market was launching a new program. The failure of seal prototypes put a potential three month delay into the project. As a result, our customer risked losing the entire project to their competition while sustaining a major hit to their brand.
The program manager told us he needed a full seal review with his European engineering team to understand the reason for failure and propose a remedial solution.
Our analysis showed the assembly process created premature compression set leading to leakage. We proposed changes which were adopted with success.
Our customer was able to get their program back on schedule without re-tooling, and confidence from their customer base was restored
