Making the mold positive

Before we can make the mold, we need to create the mold positive. This is basically a case half, except we make it out of plastic. It’s not just any case half though – it’s a reproduction of our raw casting, which means that it is dimensionally different than an actual case, and it lacks some of the holes and features that a finished case would have, because those will be machined on the case post-mold.

The process of machining the 1:1 scale case half in plastic takes a CNC machine about 30 hours to do – for one case half. Here are some progress pictures……starting to look like a case!
