How is profiled Litz wire manufactured?
Is it winded in the shape, or a round one passes thought conforming process?

\$\begingroup\$ You may be best served just by asking a manufacturer. \$\endgroup\$– HearthCommented Apr 11, 2019 at 1:32

\$\begingroup\$ You'll be surprised. Remember, they're catering to engineers, who need to know the exact characteristics of their wires. \$\endgroup\$– HearthCommented Apr 11, 2019 at 2:24

https://www.elektrisola.com/hf-litz-wire-litz/products/profiling.html This OEM shows basic materials and shape but not how it’s put together to increase fill factor.
Each strand is enamel coated then twisted into a form and bonded with several plastics in a composite bond.

The machines that produce litz wire inherently produce a circular cross-section from the bobbins which weave in and out around a circular path, so I strongly suspect that it is post-formed. The process is similar to producing textile shoelaces.
