What spec is needed for zinc plating line?


(2000)

I am starting a new zinc line but I want to know what spec will encompass the majority of industry requirements? I would like to keep my zinc to one or two processes. Is this possible?

Acid zinc barrel plating with clear or yellow chromate, and alkaline zinc rack plating with clear and yellow chromate would get you to about the 90 percent mark. But black chromate, best done on an iron-zinc alloy would be necessary to make your capacity virtually universal.

At the zinc plating shops where I have worked, the typical spec. called out, and certed to, was ASTM B633 [link by ed. to spec at TechStreet] . Ted is absolutely right I think in his response, I might add that a bright acid line with an additional alkaline zinc line would cover just about everything, but unless you are going into the bulk zinc market(low cost, high volume) set up a barrel to be able to run down either line off your workbar in addition to the racks to increase your options. Remember, you will most likely need an oven for stress relief and hydrogen embrittlement relief.

Hello ,

I agree with both previous responses , but suggest a barrel / rack setup for anyone considering a new line and trying to cover all bases. The added flexibility , especially if your new machine is configured for random loading , can add capabilities to your line that can cover multiple customer requirements
