Winding cores for energy and plant efficiency
In battery and battery foil production, winding cores are exposed to high dynamic loads on a daily basis: start and stop processes, rapid speed changes, and precise web tension control determine process stability. The decisive factor here is not the minimum weight of the winding core, but rather a defined and reproducible rotational dynamic that significantly influences energy consumption, winding quality, and the service life of the drive technology – especially when winding sensitive anode and cathode foils as well as thin separator foils.WinCore® winding cores from INOMETA are made of aluminum and are designed as a heavy-duty, reusable solution with geometrically and dynamically stable properties for demanding winding processes. Thanks to their dimensional stability, precise manufacturing, and uniform mass distribution, they support consistent winding geometry across many layers and enable reproducible process parameters in modern high-performance battery cell production facilities.

The defined rotational dynamics of the aluminum winding cores enable energy-efficient plant operation and reduce dynamic stress in the winding system. The uniform mass distribution and high geometric stability of the reusable cores are crucial here, as they allow controlled acceleration and deceleration of the winding package.These stable dynamic properties promote precise winding geometry – a key factor in the quality of electrode and separator films, where even slight fluctuations in web tension or winding tension can lead to rejects.
WinCore® winding cores are available in specific variants that are specifically tailored to the substrate type, coating characteristics, and process-related contact requirements of battery and film production:
Through the targeted selection of the appropriate WinCore® variant, the winding cores support clean, surface-optimized substrate handling – without edge displacement, unwanted material contact, or unstable release conditions. The function-specific surfaces contribute to consistent web guidance and enable uniform winding geometry across many layers.At the same time, the risk of process interruptions during format or speed changes is significantly reduced. The result is higher quality yields in electrode and separator production as well as an overall reproducible production process.
WinCore® winding cores enable energy-efficient winding processes, stable web tension, and consistent winding geometries. However, to ensure consistent quality-oriented production, all web guiding components must work together optimally.
That is why INOMETA combines the process-stable properties of the winding cores with other solutions specially developed for battery and film processes:
