Every plating line is an electrochemical cell: the anode balances ions, current distribution and bath chemistry while metal ions deposit on the cathode. Soluble lead or graphite anodes break down over time — dissolving lead, shedding sludge and letting current drift — which shows up as rough deposits, pitting, burnt edges and rejects in copper, chrome, nickel, zinc and precious-metal baths.
Dimensionally stable anodes (DSA) change this. Titanium coated with Ir-Ta or platinum keeps its geometry for years, releases oxygen instead of dissolving, and holds current density uniform across the rack or reel. The result is repeatable coating thickness, a cleaner bath, longer solution life and far less downtime — which is why modern PCB, automotive and decorative plating lines run on them.
Every plating bath fails in a different way. Match the challenge below with the anode solution Ehisen supplies for it.
PCB copper, reel-to-reel and high-speed lines burn edges and leave uneven thickness when the anode cannot hold uniform current at high density.
Dissolving lead anodes put lead into the deposit and shed sludge that blocks filters, changes bath balance and causes rough, pitted coatings.
Gold, silver, rhodium and decorative nickel show every defect — porosity, colour drift and pitting caused by an unstable or contaminating anode.
Chromic acid, sulphamate and hot alkaline solutions attack anode substrates, shorten anode life and force frequent line stoppages.
Different baths require different anode coatings and formats. Use the guide below to match your plating process with the most suitable Ehisen solution.

Consistent plating is a system result — rectifier, anode, racking and bath control must work together. Ehisen supplies the anode at the heart of the current path.
Converts AC to DC and sets the bath voltage and current density. Low-ripple output prevents nodule growth and keeps coating thickness uniform across the rack.
The current-discharging element — platinized titanium or Ir-Ta / Ru-Ir MMO in plate, mesh or rod format, rated to the electrolyte and target current density.
Workpieces are carried on titanium or copper racks and connected to the busbar. Contact resistance and rack geometry directly affect coating distribution.
Heating, agitation, filtration and dosing keep metal ion concentration, temperature and impurities within range — the basis of repeatable plating quality.
Dimensionally stable anodes can be paired with screens and shielding to control current distribution at edges, avoiding burning and over-plating.
Ampere-hour meters, thickness gauges and bath analysis log performance so plating quality is verified per lot, not just per shift.
Retrofitting or building a plating line follows a proven four-stage sequence. Ehisen supports you at every stage with engineering input and documented hardware.
Bath chemistry, current density, tank size, rack geometry and target coating thickness are reviewed, then anode format, coating and quantity are calculated.
We recommend the coating system and can supply a sample anode for bath testing under your actual operating conditions before full production.
Anodes are manufactured with batch traceability, coating inspection and accelerated life testing, with full process records shipped alongside.
Anodes are positioned, busbar connections verified, and current density checked during the trial run until coating thickness is uniform across the rack.
Buyers choose Ehisen because coating consistency, traceability and engineering response decide how long a plating anode really lasts — not just the catalogue price.
Coating applied on our own production line with a fixed formulation and controlled loading tolerance — samples and bulk runs are made to the same standard.
Every batch carries a LOT number linking substrate material, coating process records, inspection results and shipping documents.
Accelerated life testing per NACE TM0108-2008 at 10,000–20,000 A/m² converts laboratory hours into your operating rating.
Our engineers review your bath chemistry, current density and tank geometry, then recommend coating, format and quantity — within 24 hours.
Export experience across 40+ countries with complete documentation: MTC, coating reports, inspection records, certificate of conformity.
Production planned against your line schedule, with order status updates from coating to packing list.
