This past week we began the process to make the mold designs for our parts.

The idea for making the dome of the yo-yos was to oversold the 'B' logo and the stock line.

Below you will find the preliminary designs for the molds. After the feedback received we will be updating the designs to then be able to start the CAM for them. 

• Stock Line (cavity and core)

• 'B' design
  The general feedback we received for this was that for the 'B', we needed to make sure we drafted the edges by about 3 degrees. We also decided to make the extrusion a bit less than what it currently is. Furthermore, to overmold the 'B' and stock line, we will create those parts first, and from that measure them to create the overmold core molds. To overmold, the 'B' and the stock line will be fitted into the oversold core cavity, and the cavity for the overmold will be stay the same, it'll just be the dome shape. To sum up, for the first molding process ('B', stock line), we believe we can have 1 cavity for two core molds. For the overmold, we believe we can have the same cavity as before but with 2 more core cavities for the overmold. Thus, in total, we will have 5 molds to make (1 cavity, 4 cores). Below is a general picture of how it will look.

The steps before next lab are to finish the mold designs and do the CAMs for them. After that we can start machining and begin the injection molding process.
