This is the steel we will use to create the inserts for the injection mold.
We create an insert for the core and cavity (top and bottom in this case) of each part.

The shapes are roughed into the inserts on the CNC.
Fine details like snap catches are burned into the inserts using a copper electrode on an EDM machine.
This gives detail that is too small to be machined with a cutter.
