Cost of Zinc-Iron Plating 

Hai,

My job is to develop a vendor for plating at reasonable cost and I am working for a automobile company. We are using zinc-iron plating. How to calculate the cost/sq.inch (rack plating for tubular parts) or cost/kg (barrel plating)? What is the sequence of steps? What is the details we need from the plater to calculate the plating cost? Do we have any software to do these costing work?

Thanks,

All zinc-iron baths are proprietary. The sequence is the same as zinc plating except that the work goes to the zinc-iron tank instead of a zinc plating tank; and the chromate is almost always black rather than clear, yellow, or olive. Costs are not much different than zinc plating.

Please provide me about how to calculate ZINC Plating Cost.

Your question is a lot like asking for someone to provide you with welding cost, Mr. Nart. Spot welding sheet metal toys by automated machine, or fillet welding a nuclear containment building.

What are the parts (wire, hardware, castings,cosmetic items); what are the volumes (one piece, or thousands of parts per barrel and hundreds of barrels per day); what are the specs to be met (.0001" or .0007")?

I would like to have the final answer to the initial question

The original question was already answered, Ricardo -- perhaps not to your satisfaction but perhaps to the satisfaction of the original inquirer.

This is not a consulting service; rather it's a place where people involved in metal finishing meet to share camaraderie, experiences, and little tips. As such, coming here is a lot like attending a pot luck dinner; if you show up with something interesting (maybe some details of what you are doing, what you've tried, why zinc-iron interests you, what your perennial issues are) the readers are usually quick to try to share what they can. If you show up empty-handed, with nothing but an abstract request for a completely one-sided technology transfer, your question will probably remain unanswered. Sorry, that's just the way people, including platers, are.
