challenge
Challenges in fuel cell development
There were quality issues with the manual application of sealant.
- uneven application patterns
- lack of repeatability
- increased rework and scrap
Consequence | Limited process stability, high quality risks and development costs.
Task | Automating sealant application.
objective
Development of an automated, CNC-based dosing solution
- ensures maximum process reliability and precision
- which operates in a fully monitored and reproducible manner
- which serves as a technological precursor to series production
The objective:
A stable, verifiable dosing process for all fuel cell components.
our solution
CNC dosing system for precise sealant dosing
In close consultation with the customer, DoBoTech developed a tailor-made CNC system concept.
Main features of the system:
- Automated precision: volumetric dosing accurate to a tenth of a millimetre
- Intelligent process monitoring: real-time shape, position and volume checks
- Traceability: full integration into the customer’s master computer system
- Technical cleanliness: design in accordance with TecSa regulations
results
Benefit
The CNC dosing solution brought about a significant leap in quality in development production.
- Automated precision: significantly improved
- Rejects & rework: almost completely eliminated
- Dosing quality: consistent across all components
- Reproducibility: precisely traceable sealant layer and quantity
With this solution, development can be validated under near-series conditions for the first time.
