This is not exactly the first part, there is a lot of work done upstream, which will be unveiled later.
Here we sink the “molding keys” that will serve the silicone mold to be well placed in the resin shell.
All these half-spheres will be placed during the molding and incorporated into the silicone. They are kept very clean in order to stick at best and not to create bubbles.
For the molding we produced 78 keys.
