![]() ![]() Zinc plating is the least expensive plating for corrosion protection. ![]() Electroless nickel is much more expensive than zinc plating. Years ago, before it became an environmental albatross, cadmium plating could be cost competitive with zinc plating in some circumstances, but no longer. I WILL SUGGEST YOU TO CONSULT AN PLATING EXPERT WHO WILL MAKE ALL EASY FOR YOU. TO KNOW PLATING COST WE ALWAYS CALCULATE AS MENTIONED UNDER.ġ.COST OF METAL TO BE PLATED SAY ZINC/NICKEL/SILVER/COPPER/ETC.įOR THIS WE HAVE ELECTROPLATING DATA AT 100% EFFICIENCY Pricing for rack or wired work is typically per part and the thickness is a factor in that it both consumes materials (metal salts, anodes, utilities) and may be a deciding factor in the productivity of the line Gene Packman But in order to do this you must know how much will fit in a barrel, what the volume of that part on your line can be and all the other expenses (labor, overhead, environmental compliance, transportation, chemistry, return on.etc.)Ģ. Pricing by the pound is appropriate for the majority of barrel plated parts. Ted is right but I would like to bring up a few points.ġ. It's not easy, but you can figure out what it costs you to plate the parts you presently plate. and then work on figuring out why part A requires 2.7 times as much labor as part B, but half the labor of part C, etc., so that you can then estimate the cost of plating part Z. The starting point is usually to determine what a few specific parts cost you to plate - raw materials, labor, overhead, return allowance, etc. Although surface area is usually a better parameter than weight, it's still not good enough. And probably another half-dozen "Buts", too :-)Ī. And there are PVD/CVD coatings that cost more than plasma spray. But again, there are electroplatings that cost a lot more than hard anodizing, carburizing, or electroless plating. I suppose I would rank them, cheapest first, as plating (in turn ranging from zinc as cheapest through chrome platingas most expensive, hard anodizing, carburizing, electroless plating, PVD/CVD, plasma spray coating. Plasma spray coating may be cost competitive with the highest quality heavy chrome plating it competes against, but could be 100 times the cost of zinc plating. 'Lifetime' finishes and some 'gold' finishes employ a PVD topcoat on top of electro-deposited platings. A part that is to be carburized-for example, a gear-is first selectively copper electroplated to prevent hardening in the bore area. For example, anodizing applies to aluminum and not steel whereas carburizing applies to steel and not aluminum.įurther, often the processes go together. ![]() ![]() As you probably realize, Susan, these processes not only perform different functions but apply to different substrates. ↓ Closely related postings, oldest first ↓Ī. The cost of the chemistry can vary from nearly insignificant in the case of highly customized zinc plating, to fairly substantial in the case of processes such as high production volume electroless nickel plating.Īs I noted earlier, I knew one plating shop which required their estimators to have 10 years experience as a plating foreman before they were trusted to offer quotations because it can be a job with great responsibility & accountability.īut if you introduce yourself and your situation and a more specific question, with typical substrate materials, typical plating finishes, and production volumes, the readers may be able to offer at least some general guidelines. If you want a price on a particular part, you can send it out for quotes, of course.Īs in most industries, labor cost is usually a major driver and if the work is processed on a major automated plating line, amortization of equipment may be another. Sorry but I don't, and I've never seen an estimating book or training course. ![]()
