I need a machine that will cover 19 small wires with a metal shield.

Kind of like a telephone or internet wires are covered and shielded
with a plastic cover. I need do the same thing, except instead of
plastic, it will be covered in metal.

This machine, will take a bundle of 19 wires and output a cable.

This is just a free comment.
Since you are so specific about wanting a machine to cover 19 wires, I
wonder if you are really just interested in producing such cable or
more interested in finding a source for such cable or something
similar that could do the job (20 or 25 connector cable).

Certainly there are sources for similar cable:

If you need enough to order from India, there are many producers:

If I am off target, please excuse.

Thank you very much.

I already have 19 small wires produced.

I just need them to be put into some machine, so it can output 1
cabled, which is shieled in metal.

Thank you

How long will your cable be?  How professional does the solution have to be?

If this is a one-off application of not too great length, maybe you
could wrap the 19 wires with strips of alumninum foil (which is
basically what shielded cable has) and then cover it with either
heat-shrink plastic insulation or something else.
