Plating Related Questions

Question: How do I clean my silver plated (chrome plated, gold plated, copper plated) items?
Question: I have heard that chrome plating can get a condition called “chrome burn”. Can you please explain what chrome burn is and if it is a problem?
Answer: Chrome burn happens when plating is applied with a higher current than necessary or usual. Sometimes it's accidental or design fault related, however sometimes the plater will DELIBERATELY chrome burn an item to ensure adequate throw and coverage of chrome plating into all the areas of the item. It is quite common for awkward shapes to be chrome burned in the plating process. The chrome burn itself is whitish in color (appears cloudy). In restoration we incorporate extra polishing in the process to remove any chrome burn. After polishing you would never know the difference and of course you will have a better plating job as the high current has helped to cover the low points and recessed areas. See this video for a demo of removing chrome burn
Question: I am a manufacturer in the original equipment (automotive) sector. Does A Class have plating capabilities for Automotive specifications?
Answer: A Class's Automotive sector focus includes After market, Custom manufacture and Restoration work. We have processing for metal substrates AND plastic substrates. We can meet a range of different specifications but would need to know your requirements before confirming anything. We are happy to discuss high volume plating work for OEM Automotive manufacturing but have previously had a preference for servicing other areas of the market.
Question: I am a manufacturer and require parts plating services regularly. What sort of turn-around time should I expect?
Answer: For regular work of reasonable volumes we aim to deliver within 1-5 working days, depending on your process requirements.

Question: How will I know if I am getting a good quality job?

Answer: Unless you have had plating or polishing work done elsewhere you possibly won't know the difference but we like to think our quality speaks for itself.  (Actually alot of our customers tell us our work is of exceptional quality). But don't take our word for it - ask around in manufacturing or automotive restoration circles, or chat rooms.  We are confident you will hear good reports about the quality of our work.

Price Related Questions - Plating or Polishing

Question: How much will it cost to chrome my alloy car WHEELS?
Answer: Like all types of parts, it is difficult to provide an estimate without seeing and assessing your actual parts. A typical answer to this particular question (re wheels) is that the cost could be in the ball park of approximately $250 - $500 per wheel depending on shape, size and condition of the wheels. Further information about pricing and how to obtain an estimate for Restoration type work is available on the page Plating and Finishing Pricing & Quotes - Private, Restoration or Custom work. Wheels are stripped and polished prior to (and often between) plating processes. They are then plated using the 'triple plating' method of copper, then nickel, then chrome plating.
Question:I am a manufacturer of metal products and I would like an idea of what it will cost me to get my items chrome plated or gold plated?
Answer: We prefer not to provide a manufacturing or production quotation without seeing and assessing your actual parts and/or technical drawings of them. On the page Plating and Finishing Pricing & Quotes - Commercial work we have provided a form that you can download, complete and send to us with samples or drawings of your parts. This will ensure a well considered answer to your pricing question and will enable us to also assess any design issues or special process requirements. If polishing of your items is required, actual parts will be required for time trials. A phone call or email to one of our commercial customer reps may provide you with a rough estimate if you're after a quick answer.
Question: Do you do small jobs and one-off jobs?
Answer: Yes, we do small jobs, one-offs and production volumes. There is a minimum charge applicable for small jobs.
Metal & Plastic Restoration Related Questions
Question: Can you chrome plate old plastic car parts?
Answer: Yes we can chrome plate old plastic parts as well as some other plastic parts. A Class has developed a range of custom processes including various methods for treating and plating plastic parts successfully. With well over 20 years in business and being one of the most diverse finishing companies in Australia, we have amassed a great deal of knowledge and experience in plating, polishing and restoration and can usually find a solution to any surface finishing need.
Question: How long does it take to get re-chroming work done?
Answer: The average restoration job of a few car or motorcycle parts will generally take about 3-4 weeks for us to process. This time-frame can vary depending on other jobs we have at the time as well as any complications in your job, or jobs ahead of yours. Large jobs (e.g. Bumpers or severely deteriorated larger items) can sometimes take several weeks longer, depending also on any repairs or dent-knocking required.
(For information of other readers - silverware and brassware will usually take a similar amount of time: 2-4 weeks, jewellery is usually completed within 2 weeks.)
This is an old industry favourite story that sometimes helps answer a few questions about the metal plating or restoration process, especially for novice metal restorers:
Some of the population could be forgiven for thinking chrome plating is as simple as "just dipping" a job in & out of a glistening vat of molten, silvery metal. The truth is: "electroplating is a result of an electrolytically assisted anodic/cathodic reaction where the anode is a solid of the metal to be applied & the cathode is the job to be plated"! (Eeeek - what does that mean?!!!!)
The other day we had a visit from a chap who was fixing up his old Holden. With him he had a slightly rusted, chrome plated steel, bumper section. "Just dip it thanks mate" he said, "I'll be back in an hour". We went on to explain to him - "mate you'd be looking at least a few weeks to have this restored. You can imagine his shock. We went on to describe the process involved in preparing and plating his bumper section:
(After a little time waiting in line for other jobs to start)
  • 1  -  Degrease & paint strip back of section
  • 2  -  Electro chemical strip to remove chrome
  • 3  -  Chemical strip to remove nickel & copper
  • 4  -  Rust removal (Hydrochloric)
  • 5  -  Panel beat (weld, patch etc)
  • 6  -  Metal finish (polish, buff, etc) to high shine
  • 7  -  Heavy copper plate to restore base surface
  • 8  -  Re-polish to high finish
  • 9  -  Copper electroplate
  • 10 - Nickel electroplate
  • 11 - Chrome electroplate
  • 12 - inspect, touch up, wrap, complete paperwork, call customer
Crikey! The man said. Then he filled out his job form, handed over the bumper section and left - knowing it was in the safe hands of someone who obviously knows a very complex process!
Ask your electroplater for more information on the process and the variables you need to know about if restoring or re-plating important or valuable metal items.
