Production Lines for Hydrogen Components
Graebener
Features
- Machines and production lines for fuel cell and electrolyzer components.
- Reproducible forming results at wall thickness starting from 50 µm.
- Gentle forming with integrated cooling; very homogeneous wall thickness across the duct cross-section.
- Forming of pre-coated materials; different material thicknesses in one tool.
- Considerably lower tooling costs and almost no tool wear.
- 100% leak test of the formed single plate integrated directly in the process.
