Hi,
Is there any references about wire enameling (Handbook , Book, Site , ...)? Especially about quality and in line problems ?

thank you very much

Hello again Mr Nima Rahati,

Unfortunately, I am not aware of any handbook on the processing and manufacturing of magnet wire. Perhaps others will have more information Nonetheless here are a couple websites which you may find interesting.

Hitachi Magnet Wire (You can download the pdf file.)
