You're flailing in an attempt to divert attention from the fact that you're
unfamiliar with how commonplace CAD is.

I'm really laughing here, Tom, and not with you. That there are shops in North
Africa ("I happen to know..." - snicker) that still use manual machines means ---
what? There's plenty of shops in the US (and France, for that matter) that use
manuals. A glance at the cleat tells you that it is *highly unlikely* for the molds
to have been made on a manual. I am aware of what can be done on manuals - I started
using them in '74. I also know what can be done on CNC machines, with and without
CAD/CAM, by a good person, so I'm not underselling that aspect of the machine shop
world by any stretch of the imagination. But having been in machine shops as long as
I have, I have a good idea about what machines and processes are appropriate for
parts. See, I get paid real money for that particular skill.
Part of the problem here is your misconception of the molds - you're laboring
under the illusion that they take a "machined male model" and pour some stuff over it
and when it hardens, it's a mold. That method can be used for short runs on simple
parts but *real production* is, as I've told you repeatedly, done with metal molds
(aluminum or steel for the most part) that have the cavity machined into them with
mills and/or EDM. There are two pieces (or more in certain more complex molds) that
mate up with runners for the material, some means of dislodging the part (air,
ejector pins or stripper plates, for example) and a few more bits, depending on the
size and complexity of the mold and parts. See:

You're flailing again... Posing that question as a means to prove that I
understand what it takes to do production molds for a cleat is, well, stupid.
See, this is where your contrary and superior mindset causes you trouble. You're
locked into the idea that your concept of how the process works and cannot manage to
see that others might actually be familiar with the real methodology. This could
easily be a moment where you say, "Oh, so that's how it gets done" and you'll have
learned something. Instead you set about making yourself look silly. Certainly
succeeded there, I must say.
