Hi everyone, its needless to say I am new to this, I am trying to gother knowledge on this complex business of CNC industry.

I am particularly interested in learning on the processes applied onto making dies for the Lapel pin industry...I've looked all over the internet and wasn't able to find good information.
I know that several different type of pins use a die to punch brass or copper to make the impression using a press. Now my question is; how are these dies made or who makes them? what machines are needed for this process, supplies, software etc...
I appreciate if anyone can shed some light on this.
I also appreciate your patience on this.
Thanks in advance.
