relead bath in wire mnf



Warren and Dave,
We have 2 wire companies in Massachusetts that have had differing 
experience.  One has developed an induction heating system, perhaps similar 
to the one you mentioned.  They have had great success with it.  As they 
were putting in a new line, they had the room and the capital available.

The other company does not have the capital or the space, and they still 
use the molten lead bath process.  They feel that the uniformity and other 
qualities imparted by the lead bath are critical to their high quality 
product, and they don't have the financial, technical or facility resources 
to get them over the hurdle of looking into alternatives.

The case study of the first company is on our web site:

The cryogenics suggestion is intriguing, although from my long-ago 
materials science classes, I'm having a hard time figuring out how that 
would have the same effect as heat treating...

Hope this is helpful.
