Rolling – Micrometer Precision
Ultra-Thin Metal Foils with Controlled Properties
Rolling is a core process in the manufacturing of our technical metal foils - especially lead foil, tin foil and other non-ferrous metal foils. At EppsteinFOILS, we operate state-of-the-art rolling mills that enable us to produce foils with minimum thicknesses of just 0.005 mm - with exceptional precision and process reliability.
With finely tuned rolling parameters, precisely regulated forces and thermally stable conditions, we achieve ultra-tight tolerances, consistent flatness and specifically defined mechanical and physical properties - all tailored to the foil's intended application.
Process Control for Maximum Reproducibility
Our rolling mills are equipped with continuous thickness measurement, automated control systems and closed-loop regulation. This ensures that each foil consistently meets the specified requirements.
Key adjustable parameters in the rolling process:
- Final thickness and tolerance range
- Surface quality
- Flatness and dimensional accuracy
At EppsteinFOILS, we rely exclusively on rolling technology - intermediate annealing steps are not used. This makes the process efficient, material-friendly and consistently reproducible.
Application-Specific Precision Rolling
Tailored Properties for Maximum Performance
By precisely adapting rolling parameters to the intended application, we can achieve a wide range of functional characteristics. These include:
- Ultra-thin lead foils for X-ray grid applications
- Ductile tin foils for body electrodes or sealing elements
- Lamination-ready non-ferrous foils for technical composites
- Extremely flat foils for coating or laminating processes
Whether for medical electrodes, solar technology, materials testing or electronics - our customers receive foil qualities precisely aligned with their downstream processing requirements.
Surface Cleaning for Optimal Functionality
A proprietary foil cleaning process developed by EppsteinFOILS ensures that every rolled metal foil features a defined, particle-free surface. This is essential for downstream operations such as lamination, soldering, electrical contact or coating.
The surface of our foils is:
- Free from oil residues and contaminants
- Chemically and physically stable
- Ideally prepared for further processing or functionalization
Our customers benefit not only from precision rolling but also from expert consultation and development support provided by our experienced engineering teams.
