Rob and I will be exhibiting for A Class again this year and on hand to discuss your chrome or other plating (or polishing) queries.  The show goes from 24-26 October at the Royal Exhibition building in Melbourne.  We’re looking forward to seeing all the show has to offer and the fantastic classic car displays.  Hope to see you there! Cheers, Greg.

Restoration of any chrome plated car or motorcycle METAL part requires 3 main steps – Strip, polish, chrome.

Stripping can involve electric or chemical stripping, depending on the substrate material. Each layer of old plating may require a different solution to remove it. Parts that have two different metal types in the substrate – e.g. an alloy section joined to steel – can be problematic as the metal stripping process chemistry needed is different for each metal type.  The stripping process will remove the chrome, nickel and copper layers of plating as well as any rust. Any surface repairs or dent knocking are completed before polishing.

Once stripped, the part needs to be polished, to bring the surface condition up to the required depth of shine for a good plating result.  For some jobs, there will be an intermediary coating of copper plated onto the part, after which it is polished again to give greater surface depth (or to seal up a poor substrate).

The typical plating process is copper plate, then nickel plate (nickel is actually the thickest layer – it provides the strength and corrosion resistance).  The final chrome plating stage is very quick, and provides the bright and distinctive silver-blue tone we know and love, to the metal part.

For plastic chrome parts the process is a whole different ball game (give us a call if you want to know more about that)

The process is very labour intensive and there is alot of chemical science involved.  Some call it a trade, others call it a craft or even a ‘black art’.  No matter what you call this process, to us it’s simply a pleasure to give old parts new life and contribute to some really good Restoration projects!

The Chrome Plating services of A Class Metal Finishers will be on display at next week’s MotorClassica event in Melbourne, Australia from 21-23 October 2011.

Looking forward to meeting Classic motoring enthusiasts from all over Australia as well as International guests.  We will be on hand to discuss not just chrome plating services but also our range of other metal surface finishing treatments such as restoration, repairs, plastic chrome, treatments for die cast parts and a variety of other services for Classic Car and Motorcycle enthusiasts.

See you there!

Lewis Bike - Plating by A Class Metal Finishers

March 27th, 2011

27 March 2011 – A Class Metal Finishers will display their chrome plating services at today’s Jaguar E-Type 50th Anniversary.   Held at the Birdwood National Motor Museum, entrants are expected from all over Australia.  A Class is looking forward to seeing many top Jaguar Classic and restored vehicles – many of which have chrome parts restored by Greg Wood and team from A Class Metal Finishers.

The event is being run by the Jaguar Driver’s Club of South Australia and A Class is a long time sponsor of the club.  Says Greg Wood “Club members take their cars seriously – but they know how to enjoy them too.  It’s always a pleasure to provide our chrome plating or polishing services to people who know and love their cars and understand the value of a good quality chrome job.”

More information about A Class’s Chrome plating services for restorers is available here.

This weekend’s Adelaide Extreme Horsepower show is showcasing many great custom and restoration vehicles.  Among them a unique BMW Drag car said to be worth around $1 million.  Says The Advertiser newspaper, Saturday 30 Oct 2010, the many gold plated parts on this unique car have added much value to it.

A Class Metal Finishers is also present at the show, with a display stand to showcase to visitors some of the quality chrome plating and metal polishing work they can do.  A Class has restored the chrome parts on many of the cars on display at the show and although we can not claim responsibility for the gold on the BMW, certainly have added some precious gold plating to other vehicles.

A Class have been able to electroplate plastic parts for a long time – but traditionally it was only a specific material known as ABS plastic. Nowadays we can plate pretty much any type of plastic using newer methods. Since developing and extending our plastic parts plating capabilities to include non-ABS materials we have successfully chrome plated a large range of plastic parts with outstanding success in the quality of the results.

Everything from dashboard parts, to handles, flanges, trims and other fittings can be chromed.

Unlike older methods for achieving a chrome finish on non-metals, our new process bonds very well and has low surface imperfections.  We’ve received compliments all round on the results (thanks guys).  The process has opened up scope for chroming of just about any parts and is NOT limited just to Plastics – actually just about any material can be chrome plated!  Greg and staff would be only too happy to advise on the possibilities of this service – limited only by your imagination it seems!  (Other finishes, besides chrome – for example: gold, silver or nickel – are also possible for plastic items)

Plastic Chrome Parts

April 20th, 2010

We often get asked – what is the difference between hard chrome and normal chrome plating?

Chrome (short for chromium) plating is commonly performed for either DECORATIVE or FUNCTIONAL reasons.  The functional version is referred to as HARD chrome. Actually, as far as plating solutions and technologies go – aside from a few practical differences – both types are much the same.  The main difference is in the THICKNESS of the chromium material applied.

Standard chrome plating for decorative uses is a much thinner deposit (about ONE micron) of chromium over the relatively thick layer of nickel plating underneath.  Hard chrome, however, is a much thicker deposit of chromium – ranging anywhere from 5 microns to, sometimes, over 3000 microns – depending on the purpose of the coating. (A micron is equivalent to one millionth of a metre, or, one thousandth of a millimetre. In inches there are about 25 microns to one thousandth of an inch)

Because it is thicker, Hard chrome provides much greater corrosion and wear resistance, which is a benefit for many industrial uses but is overkill and expensive for decorative uses.  Hard-chrome can be used to build up surface thickness on items that have worn down – for example shafts, bores or tool surfaces.  The thicker the deposit the more uneven the surface dimensions become – thus requiring the part to be re-machined after plating.  An alternative to hard chrome, that achieves similar levels of corrosion and wear resistance, but builds up evenly, (thus avoiding the need for re-machining) is Electroless nickel.

Decorative chrome plating is still a resilient coating, it can certainly stand up to a lot of exposure and last many years (example – plated chrome parts on cars or motorcycles).  The nickel plating (and to a lesser extent the copper plating) layers beneath the chrome provide a lot of protection or corrosion resistance and, applied properly, will meet the quality and longevity standards for its intended purpose.
