Detailed answers about electroplating calculations, copper, nickel and zinc baths, surface preparation, acid activation, guided plating, troubleshooting, timers and saved reports.
What PlateLab does, who it is for and which processes it supports.
PlateLab is an electroplating process app for planning and documenting copper, nickel and zinc plating. It combines a guided 18-step workflow with plating calculators, bath-efficiency checks, DIY bath recipes, surface-preparation guidance, acid-dip guidance, timers and troubleshooting.
It is designed to help a user move from an unprepared part to a controlled plating run while keeping the important inputs, calculations and checks in one place.
PlateLab currently calculates copper, nickel and zinc electrodeposition. Each metal uses its own atomic weight, density, expected efficiency ranges, bath guidance and current-density profiles.
The base part can be selected from a broader material list, including copper alloys, steels, zinc, Zamak, lead, nickel-plated surfaces, tin and pewter. Base-material selection is used mainly for preparation and acid-activation guidance.
Both. Guided Plating explains the sequence and decisions for a first run, while Quick Plating and Bath Efficiency provide faster calculation paths for users who already know their setup.
Experienced users should treat PlateLab's generic recommendations as planning values. A commercial bath manufacturer's technical data sheet always takes precedence for temperature, pH, additives and current-density limits.
Yes. Metric mode uses square millimetres, micrometres and millilitres where appropriate. Imperial mode uses square inches, inches and US fluid ounces. PlateLab converts the inputs internally before applying the electrochemical calculation.
Keep one unit system selected throughout a guided run. Enter the total plated area, bath volume and target thickness in the units shown beside each field.
Yes. The application, Guided Plating workflow, calculation guidance and PDF reports are available in English and Turkish. Use the EN or TR control in the header to change language without losing the equivalent page.
How the guided workflow turns part and bath information into a plating setup.
Guided Plating collects the base material, surface condition, plating metal, unit system, total surface area, part geometry, bath type and bath volume. It can then guide surface preparation and acid activation before asking for bath efficiency and target thickness.
PlateLab uses those inputs to produce Gentle, Balanced and Faster setups. After you select a setup, it provides a preflight check, plating timer, final rinse, drying and metal-specific post-treatment guidance.
Use the total area that will be immersed and receive metal, including both sides, edges, holes and accessible recesses. Do not enter only the front-facing footprint.
Break a complex part into simple shapes, calculate each exposed face and add them together. A surface-area error changes the required current and metal mass directly, so a 20% area error can produce roughly a 20% current or time error.
Current is not distributed evenly over every shape. Sharp edges and projections attract more current and can burn, while deep recesses receive less current and can plate thinly.
PlateLab derates suggested current density for edges and complex geometry. This gives the deposit more margin, but physical measures such as repositioning, agitation, shields or auxiliary anodes may still be needed.
Commercial baths usually have controlled metal concentration, conductivity, additives and operating instructions. Homebrew baths vary more and generally need conservative current-density and bath-capacity limits.
For Commercial, use the supplier's stated efficiency and operating window whenever available. For Homebrew, stay within PlateLab's suggested efficiency range, test on scrap and monitor the first few minutes closely.
Gentle uses a lower current-density starting point for first runs, adhesion checks, complex shapes and less predictable baths. Balanced is the practical default for a prepared part and stable bath. Faster uses a higher current density while remaining inside PlateLab's selected constraints.
They are not quality grades. The best option depends on bath chemistry, agitation, temperature, anode arrangement, geometry and power-supply control. Faster should be watched for dark, powdery, rough or burnt high-current areas.
PlateLab considers metal and bath current density, total surface area, part geometry, bath-volume current capacity, target thickness, bath efficiency, very short run times and the maximum power-supply current when one is entered.
If a limit controls the result, the recommendation identifies it. This helps distinguish an electrochemical requirement from a practical restriction such as a small bath or limited power supply.
The electrochemistry and practical assumptions behind PlateLab results.
PlateLab uses Faraday's law of electrolysis. It calculates the metal volume from surface area and target thickness, converts volume to mass using the selected metal's density, and calculates the electrical charge required from atomic weight, electron transfer and the Faraday constant.
Bath efficiency adjusts the theoretical charge for real losses. If time is entered, PlateLab solves for current. If current is entered, it solves for time.
Faraday's law gives the theoretical metal deposited by a charge. Real baths lose part of that charge to side reactions, especially hydrogen evolution, so actual current efficiency is lower than 100%.
Using an unrealistic efficiency is one of the main reasons two online plating calculators can show different times. When uncertain, use the manufacturer value or PlateLab's expected range and confirm performance with the Bath Efficiency tool.
Current default ranges are 90-98% for commercial copper, 50-70% for homebrew copper, 90-97% for commercial nickel, 40-60% for homebrew nickel, 85-95% for commercial zinc and 50-70% for homebrew zinc.
These are planning ranges, not a certificate for a specific bath. Temperature, pH, chemistry, contamination, current density, agitation and bath age can all change real efficiency.
Current density is electrical current divided by plated surface area, commonly expressed as A/dm² or A/in². It is more useful than current alone because the same amperage behaves very differently on a small part and a large part.
Too little current density can give slow, dull or incomplete deposition. Too much can cause burning, dark deposits, roughness, gas pitting and poor coverage in recesses.
Many bench power supplies are conveniently adjusted in 0.05 A steps. PlateLab rounds suggested setup currents down to a usable 0.05 A increment, then recalculates the time from that actual setting.
For very small parts, even 0.05 A may be too coarse. PlateLab flags that resolution limit so you can use a finer-control supply or plate multiple identical parts together when appropriate.
Compare surface-area definition, thickness units, metal density, valence, efficiency and whether the other calculator uses current density or assumes 100% efficiency. Any one of these can materially change the result.
Guided Plating also applies practical guardrails for geometry, bath volume, power-supply capacity and minimum controllable run time. A bare Faraday calculation may omit those constraints.
They are convenient planning bands, not universal engineering specifications. PlateLab classifies metric targets up to 10 µm as Decorative, above 10 to 25 µm as Functional and above 25 µm as Heavy Duty. Imperial thresholds are up to 0.0004 in, above 0.0004 to 0.001 in and above 0.001 in.
The correct thickness depends on the part, substrate, service environment, finishing sequence and applicable standard.
Cleaning, activation, bath setup and timed process guidance.
Plating follows the surface underneath and does not hide scratches, pits, oxidation or polishing marks. Oil, fingerprints, compound and oxide can also block electrical contact between the substrate and deposit.
PlateLab's Surface Prep workflow covers inspection, mechanical preparation, degreasing, rinsing and the water-break test before activation.
After cleaning, wet the part with clean water. A clean surface should hold a continuous sheet of water. Beading, pulling away or broken patches usually indicate remaining oil or residue.
If the test fails, repeat degreasing and rinsing before acid activation or plating. Do not touch the clean surface with bare hands.
No. Acid activation depends on the base material, its condition, the coating sequence and the bath manufacturer's process. PlateLab lets Guided Plating users follow its acid guide, use their own validated process or continue without an acid dip.
An unnecessary or overly long dip can attack the substrate. Zinc, Zamak, lead, tin alloys and some plated surfaces need especially cautious treatment.
Treat every acid recommendation as a short activation starting point, not permission to work without controls. Read the current safety data sheet, use chemical-resistant gloves and eye protection, provide ventilation, use compatible containers and keep incompatible chemicals apart.
Add acid to water when dilution is required, never the reverse. Do not mix acids with bleach or unknown cleaners. Follow local rules for storage and disposal.
It scales copper, nickel and zinc homebrew ingredient quantities to a selected metric or US imperial bath volume. It also shows operating parameters, mixing steps and conditioning current and time from bath volume and dummy-cathode area.
The recipes are simple starting formulations and do not behave like proprietary bright-plating systems. Use suitable chemical grades, label the bath, filter it and test on scrap.
Thickness mode compares measured thickness with the theoretical target after a known run. Mass mode compares the measured mass gain with the theoretical mass gain from current and time.
Accurate area, current, time and measurements are essential. A single test can reveal a problem, but repeated controlled coupons give a more reliable efficiency estimate.
Timers, records, reports and common ways to use PlateLab on different devices.
Yes. PlateLab timers use elapsed wall-clock time rather than relying only on a once-per-second browser interval. When the page becomes active again, the display catches up to the correct remaining time.
Mobile operating systems can still delay sounds or visual updates while a browser is suspended. Keep an independent timer for critical chemical processes and do not leave a plating setup unattended.
Browsers often block audio until the user has interacted with the page, and silent mode or background suspension can suppress playback. Start the timer from its button, keep device volume enabled and allow the browser to remain active when the alarm is important.
PlateLab's visual end state remains the primary indicator. Use a separate laboratory timer for safety-critical timing.
You can use the calculators and guides without signing in. An Attalos account is needed when you want to save a calculation or Guided Plating record to your account for later reference.
Saved records appear in the PlateLab account area. You can review the inputs and result, edit the title and notes, download a PDF report or permanently delete the record.
Deletion is irreversible, so PlateLab asks for browser confirmation before removing a saved record.
Yes. Calculation results, DIY bath recipes and completed Guided Plating runs can be exported as compact PDF reports. Reports include the relevant setup, calculation details and process information available for that tool.
A PDF records the values used at that moment; it does not replace a bath log, safety data sheet or manufacturer process specification.
Yes. PlateLab is responsive and supports current mobile and desktop browsers. Selector backgrounds, timers and reports are designed for touch use as well as mouse and keyboard input.
For the most reliable timer alarms, keep the tab open, avoid battery-saving restrictions and verify browser audio permissions.
How to interpret unexpected results and where PlateLab's responsibility ends.
The Troubleshooting tab covers dull or matte finishes, pitting, peeling, blistering, burnt edges, rough deposits, poor recess coverage, cracking, dark deposits, slow or missing deposition, streaks, powdery deposits, poor adhesion, dirty baths and anode problems.
Each guide explains appearance, likely causes, first checks, corrective action, prevention and metal-specific notes. Change one variable at a time so the result remains interpretable.
Stop and inspect whether the defect is everywhere or concentrated at edges, recesses or contact points. Verify polarity, electrical contact, total area, current density, bath temperature, pH where applicable, agitation, anode condition and surface preparation.
Use a small test coupon before changing the main part. Filter visible debris and avoid adjusting several bath variables at once.
No calculator can guarantee adhesion, brightness, corrosion resistance or thickness uniformity. Results depend on measurement accuracy, bath chemistry, contamination, temperature, pH, additives, agitation, anode placement, electrical contact, substrate condition and operator control.
PlateLab provides calculation and process guidance. Validate the setup on scrap or a test coupon before committing a valuable part.
No. The current safety data sheet, chemical label, commercial bath technical data sheet and local regulations take precedence. PlateLab does not determine chemical compatibility, exposure limits, waste classification or workplace controls for your exact products.
Never use a chemical when its identity, concentration or safe handling requirements are uncertain.
Know every chemical in the setup, read its safety data sheet, wear suitable eye and skin protection, provide effective ventilation and use labelled compatible containers. Keep food, children, pets and ignition sources away from the work area.
Use a current-limited DC supply, verify anode-positive and cathode-negative connections before energising, protect against spills and short circuits, and follow local hazardous-waste rules.
