Want to install hot blackodizing processJune 25, 2012
Q. Tell me about more on hot blackodising like --
1. Chemical used for process
2. What temperature
3. And how much time will dip into the chemical?
I want to start this process because no one can give me good quality.
I'm a press part manufacturer and I have an export order which I want to know that if there is any suitable way to do the plating in our factory. Is there any corrosion during sea shipment of blackodising plating? Suggest me for other plating method. Black zinc will be much costly than blackening.

A. Hi Kiran.
I honestly think you should shop much harder for a blackodizing service or other metal finishing process jobshop rather than attempting to do it yourself -- but you can certainly contact a supplier of proprietary blackodizing processes and have them give you the full technical data sheet for operating conditions if you insist.
Black zinc is the least expensive black electroplating process, but is more costly than blackodizing. Black zinc will probably not survive sea shipment without proper packaging, but it has a much better chance than blackodizing -- which offers almost no corrosion resistance.
I can hardly think of a better recipe for financial disaster than to take a large order for overseas shipment of blackodized components and try to do the process yourself for the first time. Please find a really reputable plating jobshop who has experience in blackodizing and black zinc, and overseas shipment, and trust their advice. Or else, retain a metal finishing consultant to guide you through this process.
