Value

Precise heating for sensitive foil materials.

  • Copper foil and aluminum foil need controlled heating to protect surface and material properties.
  • Automatic temperature control, records, alarms, and energy monitoring support repeatable precision foil annealing.
  • AKS cooling and atmosphere philosophy can be tuned around non-ferrous foil surface requirements.
Selection notes

Foil process design depends on material sensitivity.

For copper foil and aluminum foil producers, the best furnace route is not decided by furnace temperature alone. AKS reviews foil thickness, width, alloy, surface target, tension window, and required uptime before recommending the annealing line design.

  • Copper foil route: protect conductivity-related material targets while controlling oxidation.
  • Aluminum foil route: balance ductility recovery, surface cleanliness, and web stability.
  • Both routes depend on protective atmosphere, cooling configuration, and high-precision tension control.
