Cathodic electrodeposition film

2002

We are a supplier of sheet metal stampings to the automotive industry and to other unique commercial accounts. Some of the part numbers require E-coating per strict specifications. Can an E-coat line (black) be set up without too much technical "know how"? What is involved? Any input would be appreciated.

Sincerely,

Yes, you need a fair amount of technical expertise to run an E-coat line. Now in some cases you can get that expertise from your supplier, but your outfit would have to be a big chemistry user to justify it. The equipment to set up an e-coat line for long term use is also fairly expensive (esp. compared to powder coating). However, it is very environmentally friendly process (esp. compared to plating.) Our company did a great deal of research before setting up our line (cost 1.2 million) and it is only justified if you are a pretty large user. Hope this helps! Mike Wells
