DC and DC/AC solutions for precise layers and repeatable colours
Anodizing, hard anodizing, and electrolytic aluminium colouring are among the most important decorative and functional surface treatment processes. Coating quality, colour consistency, and process efficiency depend on precise control of current density, voltage, and—depending on the method—AC components. plating electronic provides process-engineered power supplies and control concepts with one clear goal: stable operation, practical usability, and repeatable results.
Switch-mode technology for compact, efficient plant concepts
For anodizing applications, we rely on proven switch-mode technology with advantages that matter in practice: compact designs, high efficiency, water-cooled options, and robust concepts for industrial environments. Especially with process-close installation, cable runs can be reduced and plant layouts can be designed more efficiently.
Process control for anodizing and hard anodizing
To regulate current density and process sequences reliably, the control concept is critical. Programmable controllers support functions such as automated process regulation, surface/area detection, and corrections that help stabilize results and reduce operator effort—particularly in demanding applications such as hard anodizing or titanium anodizing.
Colouring with variable sine waveforms and defined process time
For colouring processes, plating electronic offers solutions that enable a variable sinusoidal waveform during colouring. This allows process times to be influenced deliberately: for lighter colours, colouring time can be extended to increase accuracy and repeatability. For darker colours, shorter colouring times can increase bath throughput and reduce energy consumption. The result is more control over colour nuance and productivity—without unnecessary complexity.
DC/AC pulse technology for a wide range of applications
In many applications, DC/AC pulse technology provides a strong foundation for stable anodizing and colouring. Depending on the system concept, power can also be scaled via parallel connections to cover a broad range of process requirements. The key is proper engineering of the complete setup—power, control, interfaces, and plant environment.
