Heating rollers in calendering and laminating processes<\/h2>\n\n\n\n

In battery manufacturing, thermal process control plays a crucial role in product quality, energy efficiency, and reproducibility. Especially during the calendering and lamination of coated anode and cathode material, aluminium and copper foils, and separator foils, an exact, uniform temperature distribution across the entire roller width is essential.
The smallest thermal fluctuations can cause inhomogeneous material properties, delamination, bubble formation, or adhesion issues.
With INOheat\u00ae<\/sup>, INOMETA offers electrically heated roller systems<\/a> that generate process heat directly within the roller body. Eliminating liquid heating media, external storage tanks, and piping not only reduces space requirements but also lowers energy consumption and simplifies plant peripherals. The result is fast response times, homogeneous heat input, and maximum integration into modern production processes.<\/p>\n\n\n\n

Thermal performance and system integration of INOheat\u00ae<\/sup> heating rollers<\/h2>\n\n\n\n

The heat generated locally in the roller body acts precisely where it is needed \u2013 on the substrate surface. Depending on the design, INOheat\u00ae<\/sup> rollers can reach temperatures of up to 220\u00b0C with a uniform surface temperature distribution and tolerances of less than \u00b11\u00b0C. The precise positioning of the heating elements allows for targeted control of the temperature profile, which is especially important for temperature-sensitive or multi-layer coating systems used in solid-state or thin-film cell production.
Especially when processing sensitive material systems such as metallic foils (e.g., aluminium, copper foils) and porous separator foils, precise temperature control is a key quality factor.
For process-critical applications, you can choose from options like temperature-resistant hard metal surface coatings, non-stick coatings, or elastic covers in various degrees of hardness.
Thermal decoupling is also a key part of the design. The roller’s targeted construction minimizes unwanted heat transfer to adjacent components \u2013 an added benefit for process stability and machine protection.<\/p>\n\n\n\n
