Anodizing is an electrochemical process that thickens the natural oxide layer on a metal — most commonly aluminum — by making the part the anode in an electrolytic bath. The resulting oxide layer is harder, more corrosion-resistant, and can be dyed before sealing.

Cost depends primarily on automation level, tank count and material, rectifier capacity, and whether wastewater treatment and ventilation are included. See our full cost breakdown for ranges by configuration — the honest answer is that budget and configuration should be worked out together, not estimated from a single number.

A complete plant needs process and rinse tanks, a hoist or automated transport system, a DC or pulse rectifier, chemical dosing and bath-analysis equipment, heating/cooling, local exhaust ventilation with scrubbing, a PLC/SCADA control system, and wastewater treatment.

Anodizing wastewater requires pH neutralization, removal of dissolved metals, and — where cyanide or chromium are present — specific destruction/reduction steps before discharge. EVESS's EGC technology treats these as a single mixed stream rather than requiring segregated pretreatment lines.

Manual lines suit small-batch or prototype production with 1–2 operators per shift. Semi-automatic lines automate transport while keeping operator-guided process steps, for medium volumes. Automatic lines run continuously under PLC/SCADA control with only supervisory staffing, for high-volume manufacturing.
