Industrial solutions
In battery and fuel cell production, cleanrooms and dry rooms impose particularly stringent demands on the materials and production equipment utilized. Moisture, dust, or impurities can cause lasting damage to the sensitive electrode tracks and metallic foils, thereby impairing the performance and lifespan of the energy storage devices. Furthermore, the winding process necessitates precise and consistent material guidance to prevent tension loss, wrinkling, or material distortion.The innovative WinCore® winding cores from INOMETA are specifically engineered to address these challenges. They are designed to support low-dust, low-abrasion operation, maintain dimensional stability under varying temperature and humidity conditions, and contribute to smooth, consistent web handling. Consequently, they support a high level of process reliability, reduce rejects, and help to significantly minimize downtime in one of the most demanding production areas of the energy storage industry.
As reusable, process-stable winding systems, WinCore® cores are designed for repeated use and can help reduce the need for disposable cores in winding processes.

For WinCore® winding cores, INOMETA employs state-of-the-art high-performance materials such as aluminium, CFRP, and GRP, carefully selected according to specific requirements concerning weight, rigidity, and temperature resistance. Aluminium exhibits particular excellence due to its outstanding thermal stability, whereas CFRP and GRP offer compelling benefits with their low weight and high strength. This material diversity enables optimal adaptation to various production processes and contributes significantly to durability, process efficiency, and process reliability. Compared to conventional paper cores, WinCore® winding cores offer several technical advantages. They are designed to withstand higher mechanical and thermal loads, support low-dust and low-abrasion operation, and maintain dimensional stability even under demanding process conditions.As a result, they provide a durable alternative to conventional paper cores and support the transition to reusable core systems in battery and fuel cell manufacturing.
WinCore® winding cores are indispensable in the early production phases of battery and fuel cell manufacturing. They function as precise carriers for sensitive metallic foils, such as copper, separator- or aluminium, which serve as current collectors in battery cells. Their high concentricity ensures tension-free and crease-free winding of these foils, effectively preventing mechanical stress and material deformation. This gentle handling is essential for the functionality and reliability of the subsequent cells. With WinCore® winding cores, manufacturers benefit from improved material quality and enhanced process stability throughout the substrate and electrode production value chain.
In the critical production steps of coating, drying, and slitting, precise and dependable winding cores are essential for a trouble-free material flow. WinCore® winding cores from INOMETA excel with their outstanding thermal resistance, reliably preventing deformation of the cores even at elevated temperatures. Their precise geometry ensures a consistent unwinding and winding process, which significantly contributes to uniform coating quality. By preventing material displacement or wrinkling, rework and rejects are substantially reduced. These process-reliable winding cores therefore enhance the efficiency and cost-effectiveness of the entire battery and fuel cell production process.
In cell assembly and downstream processing steps, such as the precision cutting and stacking of electrode webs, durable and reusable winding cores are an important component of reliable production processes. WinCore® winding cores from INOMETA are designed for repeated use and provide long-term dimensional stability under demanding operating conditions. Compared to disposable paper cores, they can help reduce process interruptions associated with core replacement. Their reusable design also supports production concepts based on reusable core systems throughout the battery and fuel cell manufacturing value chain.
Production interruptions and material losses represent significant challenges in battery and fuel cell manufacturing. INOMETA’s WinCore® winding cores establish new benchmarks in this regard, owing to their exceptional dimensional accuracy and stability. Their precision manufacturing ensures uniform and tension-free guidance of copper, aluminium, separator- and other delicate foils, effectively preventing unwanted machine halts and disruptions in the production flow.The minimization of wrinkling and material distortion leads to a substantial reduction in rejects, directly translating to enhanced system availability, increased production capacities, and improved economic efficiency of the production lines. WinCore® winding cores support stable and efficient production processes in the modern energy storage industry.WinCore® winding cores from INOMETA particularly demonstrate their advantages in sensitive production environments such as cleanrooms and dry rooms. Manufactured from durable and high-quality materials like aluminium, CFRP, and GRP, they do not generate any dust or fiber discharge – a decisive advantage over conventional cardboard cores, which often lead to contamination in these environments. Furthermore, these dimensionally stable winding cores maintain their exact shape permanently, even under demanding conditions, ensuring consistent material guidance without irregular web lengths.
WinCore® winding cores offer a range of benefits that combine operational efficiency with reusable core technology:
As aluminium solutions for use with expansion shafts and chucks, WinCore® Ecoline winding cores combine tight concentricity with an optional PROTEK® coating for wrinkle-free, reusable (1,000+ cycles) winding in battery and fuel cell production. The Proline version builds on this with custom-made end inserts for extra robustness and maximum dimensional accuracy – ideal for highly automated production processes with the highest demands on process reliability.
The adhesive surface of our WinCore® winding cores with winding support lets thin battery foils be applied without double-sided tape – cutting changeover times and making the core instantly reusable. See how this works specifically for separator and electrode foils.
For abrasive electrode materials, INOMETA offers WinCore® winding cores with an FDA-compliant, cut-resistant surface – resistant to cutter-knife damage and built for the most sensitive areas of battery production. See why this matters specifically for LFP, NCM and LMO slurries.
