Fully automatic anodising line for aluminium profiles

In China, a fully automatic anodising plant is a convenience; in Europe it is arithmetic. A manual plant producing 200–300 tonnes of profiles per month needs 8–12 people per shift for racking, transferring and unracking. At European wage levels that crew, on two shifts, costs roughly the lower end of this line's price — every single year. The automatic line runs the complete cycle — profile stacking onto flight bars, programme-controlled transport between tanks, unloading and destacking — with 1–2 operators at the main HMI panel.

The process sequence is classic: degreasing, etching, anodising, electro-colouring and sealing. The difference is that coating thickness is set on the panel (typically 5–25 μm) and held by the controller from the counted electrical charge, not by an operator's feel — which ends the shift-to-shift repeatability debate. Tanks are powered by energy-saving IGBT rectifiers and built from PP, stainless steel or FRP-lined concrete. A worthwhile option is the ED module (electrophoretic coating): a clear or tinted lacquer applied electrically in the same line, a quality standard across Asian markets and increasingly specified for export profiles — including solar frame contracts. (US spelling: automatic anodizing line.)

Honestly: this is a project-class investment, not an off-the-shelf product. It needs a layout design for your building (which we do free of charge), utilities, effluent neutralisation and EU conformity work on guarding and safety circuits — we price that work openly instead of pasting a dubious CE sticker; the details are in our guide to CE marking of Chinese machinery. Below roughly 150–200 t/month a compact manual line is the more sensible entry point; above it, the wage difference alone pays back the machinery difference in 3–5 years. Send us your volumes and we will run the numbers both ways.
