Core Technology Principle & Process

The machine employs a precision conductive roller system, which allows the continuous metal coil to act as the anode in a controlled electrolyte solution. Under a regulated electric current, metal ions dissolve directionally, creating precise etched patterns outside the masked protection areas. The process is clean, controllable, and highly efficient.
