Foil process data

Built around ultra-thin foil handling, not furnace temperature alone.

AKS starts with foil material, thickness, width, surface target, and tension window, then engineers heating length, cooling capacity, atmosphere, drive control, and web stability.

Why AKS

Heat, atmosphere, cooling, and tension control in one line.

AKS focuses on the sections that decide ultra-thin foil value: accurate heat, protective atmosphere, cooling stability, and high-precision tension control that keeps the web flat and stable.

  • Precision drive and tension coordination reduces foil wrinkle, wave, and breakage risk.
  • Protective atmosphere supports bright surface quality for stainless steel, copper, and aluminum foil.
  • Cooling temperature and air volume are controlled to improve ultra-thin foil flatness.
Foil line value

Performance targets that matter after installation.

AKS links furnace engineering to practical foil value: surface brightness, stable tension, lower defect risk, and repeatable ultra-thin material annealing.

Stable

Ultra-thin web handling

High-precision tension control helps keep stainless steel foil, copper foil, and aluminum foil stable through heating and cooling.

Bright

Controlled surface finish

Protective atmosphere and accurate temperature control support clean, bright foil surface quality.

>98%

Yield and uptime focus

Designed for precision foil annealing, reduced rework, and stable continuous production.
