| Post subject: | Electro plating Kits? |
I am looking at doing my own zinc plating because I have lots to do. I am thinking of getting one of these kits. Has any one used a kit like this and are there any do's and dont's I should know about? http://www.janekits.com.au/mainframe.php |

Yeah I bought the combined zinc and nickel plating kits from there. The zinc one works OK on bigger stuff, but if you want to plate small nuts and bolts etc I'd send them out to someone who does barrel plating, instead. I've not tried the nickel plate kit, it's supposed to be heated to 50C or so and I haven't got a round toit, yet.

Find out as much as you can about this before you buy, and try to see some finished product if you can, there is a lot more to electroplating than most people think, I say this as a qualified Electroplater |

Kev As a matter of interest, The zinc plating kit, Do they use an acid or alkali electrolyte, ( my guess is Acid ) also does the kit include zinc anodes? or do you have to add chemicals when the zinc ions are depleted |

Yes there is some stuff in the kit to top it up with. I'll bring the book next time I come down.

Totally agree. I bought one from somewhere on the Central Coast yrs ago, turned out to be a waste of money. Preparation critical apparently cos a lot of stuff I did, the plating eventually peeled off. You live & learn.

Plating does not like any contaminenets whatsoever - thats why it falls off!Its even more critical than preparing surfaces for painting Cleaning process for those interested is as follows Strip any remaining cadmium or zinc plate - use dilute Hydrochloric acid -3 parts acid to 1 part water immerse in Zonax metal cleaner - concentrate 6oz per gallon ( sorry about the use of imperial ) at near boiling point for 2 t0 5 mins Wash in cold water Scub with pummice powder - Ajax is OK- on a clean laminex board with a toothbrush Wash Acid etch in 20% solution of HCL for 1 minute in a plastic bucket Rinse Then plate Dont even think of touching the item once you have started - almost impossible to wire up for plating The best plating solution is a chloride bath made up of Zinc chloride and potassium chloride but the Ph is critical Acid zinc baths are the easiest to set up but there are drawbacks Having said all this the right way to do it is send all the bits you need doing to a shop that does barrel plating You can even asked it to be passivated so it finishes a light gold colour to match the BMC finish |
