Windabillty is dependent upon many things including the coating on the wire, lubricant if any, the spool (size, shape, and design), winding tension, traversing rate and quality of traverse, and etc.

You have asked similar questions in two areas. Windability depends upon many things. First the coil winder must have his equipment in order meaning alignment of guides, tension, cleanliness, proper training of workers, etc.

As the processor you need to know what your customer needs. What kind of lubricants can his finished product tolerate, what exact enamel he needs, can you use one with friction reduction included in the enamel formula (beware any silicone oils as they can deactivate the catalysts in your ovens) . There are a variety of lubricants that you can use and I suggest you ask your enamel supplier for some suggestions.

Since I know that you do inline drawing, again I want to encourage you to read up on inline drawing, use the right supply wire, and reduce it at least 30% but not more than about 80%! If you do this you should be able to use your pre-annealer to clean the wire and let actual anneal take place in the oven

Apply the desired lubricant just before you spool the wire.

If you are talking about windability on your takeup, then lubricant and traverse rate will also affect it. You have to use a lubricant that is suitable for your customer.
