Why INOMETA relies on aluminium, CFRP and GRP for winding cores<\/h2>\n\n\n\n

For WinCore\u00ae<\/sup> winding cores<\/a>, 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\u00ae 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<\/a> and support the transition to reusable core systems<\/a> in battery and fuel cell manufacturing.<\/p>\n\n\t<\/div>\n\n<\/div>\n\n\n
