Product Introduction
Copper foil manufacturing equipment refers to the machinery and systems used to produce copper foil through the electrodeposition process. The core components include the cathode drum and the electrolytic cell.
Cathode Drum
The cathode drum is a critical component in copper foil electrodeposition. It is a cylindrical conductive drum that serves as the cathode in the electrolytic cell.
Typically made of stainless steel or titanium
Surface is finely polished to ensure uniform and smooth copper deposition
Rotates continuously during operation to form consistent copper foil thickness
Electrolytic Cell
The electrolytic cell is the core unit where copper electrodeposition occurs.
Anode: High-purity copper
Cathode: Rotating drum (stainless steel or titanium, copper-coated)
Enables controlled deposition of copper onto the drum surface
