Winding cores for the secure guidance of sensitive electrode and separator foils<\/h2>\n\n\n\n

The production of aluminum and copper foils, separator foils, as well as coated anode and cathode materials for lithium-ion batteries places the highest demands on the winding process. The materials used are extremely thin, mechanically sensitive, and often functionally coated \u2013 even the smallest unevenness or edge deformation can impair the quality of the entire winding. INOMETA offers winding cores specially developed for these applications, which ensure maximum web stability, gentle material handling, and high process reliability \u2013 both in dry and wet processes.<\/p>\n\n\n\n

Special requirements for processing thin, functional layers<\/h2>\n\n\n\n

Separator foils, aluminium and copper foils, as well as functionalized electrode materials \u2013 such as anode and cathode coatings \u2013 pose a particular challenge in the winding process due to their low thickness and high sensitivity to mechanical stress. Even the slightest shear forces, uneven tension, or edge deformation can lead to web disruptions, shifts, or material breaks \u2013 especially at high winding speeds. This is exactly where INOMETA’s reliable WinCore\u00ae<\/sup> winding cores with winding support<\/a> come into play: their high concentricity and precisely manufactured geometry ensure that the web material is evenly supported, thus reliably preventing damage to the material edge.
The smooth or functionally coated surface reduces the risk of particle adhesion or cutting damage and ensures consistent web guidance throughout the entire winding process.
Thanks to the integrated winding support, the use of double-sided adhesive tape is eliminated \u2013 even the thinnest battery foils are laid cleanly, adhesive-free, and with low stress directly onto the core. This prevents defects and ensures perfect first windings, without preparatory or subsequent work steps. This prevents misalignment and ensures perfect first windings without any preparatory or subsequent work steps. For applications involving abrasive or sharp-edged materials, INOMETA offers cut-resistant winding core variants that reliably prevent cuts in the core surface and damage to the first winding layers.<\/p>\n\n\t<\/div>\n\n<\/div>\n\n\n

Material-friendly winding core solutions for sensitive battery foils<\/h3>\n\n\n\n

Choosing the right core is crucial for damage-free processing of sensitive film webs. INOMETA cores combine mechanical precision with innovative surface technologies to ensure uniform contact. Additional options such as winding aids or cut-resistant surfaces support automated, clean processing and reduce downtime during operation.
The media-resistant properties of WinCore\u00ae<\/sup> winding cores are particularly beneficial in sensitive production environments such as drying rooms or clean room zones. The materials used are resistant to moisture, oils, and common cleaning agents, which prevents swelling due to ambient humidity. The smooth, closed surfaces are low in particles and easy to clean \u2013 a decisive advantage for applications with strict quality and hygiene standards. For thermally stressed processes such as accelerated drying phases or winding areas near ovens, temperature-stable variants with increased dimensional stability are also available.<\/p>\n\n\t<\/div>\n\n<\/div>\n\n\n
