Corrosion-critical parts
Stated as an alkaline high-corrosion plating process that meets the needs of the European and American automotive industry.
Fengfan's Eco-Zinie 300 is an alkaline zinc-nickel alloy process built for automotive-grade corrosion protection, and the company works as a hands-on alkaline zinc nickel plating process supplier that supports bath setup, pilot runs and long-cycle control. For lines already in production, the same team also serves as a dependable zinc nickel plating chemicals supplier, keeping additive supply, technical response and export packaging aligned with continuous plating schedules.
Eco-Zinie 300 is an alkaline zinc-nickel alloy process. These are the conditions the product page states it is built for, and the points worth confirming before a line trial.
Stated as an alkaline high-corrosion plating process that meets the needs of the European and American automotive industry.
Described as having a wide range of current density and high efficiency, which is what keeps a running line inside its cycle time.
Suitable for the rack and barrel plating process, so the same chemistry serves both part-presentation formats.
Designed for bath stability and system integration, with continuous filtration and a broad operating window.
Eco-Zinie 300 is supplied as a modular additive system of distinct components. Each one is dosed separately, so deposit characteristics can be tuned without changing hardware.
Listed in the operating table at 4 to 12 ml/L, with 8 ml/L optimal for rack work and 10 ml/L for barrel work.
The complex agent in the system, dosed at 90 to 120 ml/L. It is the component behind the stated dispersion and even metal distribution.
The brightener, dosed at 0.5 to 2 ml/L. The page describes the resulting layer as white and bright.
The nickel supplement, dosed at 12 to 16 ml/L, which is how the 11 to 16 percent nickel content in the deposit is held.
The system is stated to support continuous filtration cycles that keep the bath clear, and to be compatible with standard passivation and cleaning sequences, so it slots into an existing alkaline line rather than replacing it.
The published operating window for Eco-Zinie 300, with the optimal values given separately for rack and barrel plating. Values are quoted as the product page states them.

Process flow as published: alkaline chemical degreasing → washing → acid degreasing → cleaning → activation → cleaning → zinc-nickel alloy plating → cleaning → bright dip (dilute hydrochloric acid, pH 3.5 to 4.0) → cleaning → passivation → cleaning → sealing → dry curing. Where a value is not documented for your line, confirm it with the technical team rather than assuming an industry range.
What the product page states about the deposit itself, and what has to be requested because it is not published.
Because the corrosion and thermal-shock statements depend on the passivating agent used, keep the process and its matched passivation on the same specification sheet when you request a quotation.
Structured the other way round: start from what the line is doing, then check the documented parameter that governs it. Every figure below comes from the operating table above.
| What you observe | Documented parameter to check | Published range |
|---|---|---|
| Nickel content drifting low in the deposit | Eco-Zinie 300 C nickel supplement dosing | 12 to 16 ml/L |
| Uneven distribution or poor throwing power | Eco-Zinie 300 A complex agent, plus filtration continuity | 90 to 120 ml/L; 1 to 2 filtration cycles per hour |
| Deposit dull rather than white and bright | Eco-Zinie 300 B brightener, and the bright dip pH | 0.5 to 2 ml/L; bright dip pH 3.5 to 4.0 |
| Burning or rough deposit at high current | Cathode current density and zinc metal content | 0.5 to 4 A/dm²; 5.0 to 10.0 g/L Zn²⁺ |
| Caustic balance drifting on a long run | NaOH concentration | 110 to 135 g/L |
| Results varying through the day | Bath temperature | 23 to 28 °C, with 26 ± 2 °C optimal |
| Consumption higher than planned | Make-up component and bath maintenance routine | Eco-Zinie 300 MU at 4 to 12 ml/L |
This matrix maps symptoms to the published parameter set. It is a starting point for a technical conversation, not a substitute for your own bath analysis.
What integration and supply look like once the process is chosen, using the terms stated on the product page.
Stated to integrate into standard industrial plating lines without extensive adjustments, and to suit both automated systems and manually controlled setups that need high reproducibility.
Continuous filtration keeps the bath clear and in balance. The process is described as extending bath life and lowering chemical consumption and maintenance frequency.
Straightforward dosing schedules are stated, supported by technical resources that help repeat the process in manual or automated lines.
Stated at 200,000 pcs per day, which is the figure to compare against your own monthly output before a continuous-supply agreement.
Standard export packaging, with delivery stated at 15 to 25 working days. Minimum order quantity and price are both negotiable.
L/C, D/A, D/P, T/T, Western Union and MoneyGram are listed as accepted terms.
Compliance documents are matched to the order: the product page does not publish a REACH, RoHS or other certification status, so ask for the current document set for your market rather than treating certification as included.
No price is published for the process, so the useful exercise is to look at what moves cost per plated part and get those numbers confirmed on your quotation.
Bath life and additive dosing are the two levers the page names: the process is described as engineered to increase bath life and minimise chemical consumption, with dosing schedules that keep repeatability high.
Continuous filtration at 1 to 2 cycles per hour is part of that, because a clear, balanced bath is what keeps consumption predictable.
Bring your monthly volume, tank volume, rack or barrel mix and target nickel content. Minimum order quantity and price are both negotiable, and delivery runs 15 to 25 working days, so the quotation can be built around your supply schedule.
Ask for the consumption figures per 1,000 parts so the cost per plated part can be compared against your current process.
Every figure in this module that would normally be a price or a consumption rate is deliberately left to the quotation: the product page publishes none, and a number invented here would be unusable in a costing sheet.

it deposits a zinc-nickel alloy coating on steel parts, and it is chosen where corrosion protection has to hold up longer than plain zinc. this page presents the eco-zinie 300 process for automotive-grade work such as fasteners and stamped parts.
bath setup, pilot runs and long-cycle control are handled with the plating line rather than sold as chemicals alone. production parts are run through pilot testing before the bath is committed to full output.
the eco-zinie 300 is the zinc-nickel option on this page, while the related fengfan lines cover bright alkaline zinc for rack and barrel plating (zn 50), a cyanide-free alkaline zinc line (zn-500) and a sulfate zinc brightener (sz-30b). choose the zinc-nickel process where corrosion demand is highest and a zinc-only line where a bright zinc finish is enough.
confirm the source manufacturing capacity, the nickel content your specification calls for, and the additive consumption your line will run through. those answers decide the pack size and the replenishment rhythm.
the same team supplies the additives, answers technical questions and prepares export packaging, so replenishment, technical response and shipping follow the plating schedule. consistency is judged against the process rather than against a single order.
