Depositioning

Aspinalls' latest design of copper foil electrodepositioning machine is a comprehensive, symbiotic arrangement of technologically advanced facilities offering our customers a reliable, consistent and enduring production unit operating to the principles first described by the likes of Faraday and Edison decades ago.

These facilities include a rotating drum cathode, (with a drive control system allowing management of the drum speed to better than +/-0.5%), which is maintained at a close tolerance gap to a pair of submerged curved anodes. The condition of the cathode plating surface is maintained by applying an automatically controlled polishing brush between production runs. A commutator contact system allows the plating current to flow from a rigid busbar system to the rotating cathode at minimal voltage drop. An internal electrolyte distribution system, fixed between the anodes at the base of the machine, ensures a consistent and controlled supply of plating liquor throughout the cell. As the drum rotates into the electrolyte filled anode-cathode gap, copper is deposited on its surface. As it emerges from the electrolyte, the deposit is washed and squeegeed before being peeled from the cathode surface as a continuous foil product. An integrated rewind system, with control software linked to the drum drive, allows the foil to be accumulated in roll form on an insulated mandrel at a controlled tension throughout its manufacture.

At a consistent plating current, the mean thickness of the deposit is a function of the speed of the drum cathode rotation, which can be controlled to consistently produce foils with a nominal thickness at a set point of 10mm to 175mm.

Aspinallsí electrodepositioning machines are routinely operated at currents exceeding 45000 amps and many have been in almost continuous service for more than 10 years.
