The Graebener® Engineering

Essential for Plate Design and Line Technology

We analyze your design regarding manufacturability and work with
you to develop
modifications so that your plate can be successfully
manufactured – also with regard to the necessary features for an economic series production. You do not have a design yet? We would be pleased to implement your idea as a
CAD model for you.

For your own production, we analyze all production steps – from the coil to the finished bipolar plate – and develop a scalable and future-proof line concept based on the analysis and in consideration of your infrastructure.

The Graebener® Production Laboratory

From Prototyping to Small Series Production

In our production laboratory, we are able to verify the manufacturability of your bipolar plate design using a selected area as test geometry – this way, you obtain initial results quickly and cost-effectively. This also applies to the design optimizations we work out.

With the continuously optimized and patented Graebener® technology used in the laboratory, we are able to produce smallest lot sizes and small series of your plate design – and later transfer the production parameters one-to-one to your own Graebener® production line.

Your Graebener® Production Lines

From the Individual Machine to the Line

We realize your individual single machines for hydroforming, cutting, welding and straightening including all tools.

For larger and more complex projects, we develop tailor-made and scalable lines for series production – from the coil to the finished bipolar plate.

In addition, we support you with our stack press in the technical testing of your stacks.
