Assembly and final assembly with the highest repeat accuracy
From battery packs with laser-welded cells to BMS integration and complete drive systems: With OCEAN TEC – FLOW, we manufacture precisely, transparently, and reliably – with full traceability at every step.
Precision in every step
We take over the manufacturing and final assembly of your products – with the highest repeat accuracy and according to the strictest quality standards. Through structured processes and the use of the latest tools, we ensure efficient, reliable, and scalable production.
From the assembly group to the final product
Our manufacturing covers the entire assembly process – from outsourced components that are processed by us to complete end products that leave our production. Quality, precision, and traceability are at the forefront.




Battery Packs – Precision in Every Detail
Custom battery packs are being developed in our house:
- Laser welding of cells for maximum durability and safety
- Assembly of BMS electronics (including firmware integration)
- Final assembly of complete battery packs, ready for immediate use
Every step is documented and verifiable in the OCEAN TEC – FLOW system.
Electric drive systems
Complex drive units, such as our jet propulsion systems for maritime use, are also assembled by us:
- Integration of power electronics and motor control
- mechanical assembly of impeller and housing components
- electrical testing and quality assurance up to final acceptance
OCEAN TEC - FLOW
digital process safety
With our own manufacturing system OCEAN TEC – FLOW, we ensure that every assembly step is documented without any gaps:
- Component capture via QR/Data Matrix code
- Assignment to Batches & Serial Numbers
-
Consistent traceability from the assembly group to the final product
Integrated Quality Assurance
Quality is not a downstream step, but part of the process:
- Automated quality checks are directly integrated into the production process for each assembly.
- Inspections are carried out seamlessly during assembly
- Comprehensive documentation of all test results
Transparency & Efficiency
With OCEAN TEC – FLOW, not only are material and process data recorded, but also the start and end times of each assembly. This allows for precise monitoring, analysis, and continuous optimisation of time and cost expenditures.
