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.

After our chat with Joe and Dave last Wednesday, October 10th, the team made some changes to the mechanism and aesthetics of our yo-yo.

• Bitcoin logo side
  1. The Bitcoin logo will snap-on to the dome or will be over-molded. The manufacturing technique is still TBD. 

• Stock Market side  
  1. The stock market line will be be a snap-on, an overmold or will be painted on. Thus, we have deterred from the original idea of making the line a channel in which a liquid with gold glitter (like that in snow globes) will be inserted and will be able to move around freely within the channel.                                                                 

• Shaft for string gap
  1. As for the shaft originally designed, we will change to those manufactured in class because this knot and bolt design could cause some problems with the string while the yo-yo is spinning. Firstly, the string could get touched, and secondly, there might be too much friction and the yo-yo will not be able to go back up.
  2. Below is the old design and right below that one is the design of the 008 shaft, the one we'll be using.

• Thermoformed packaging
  We know have the design of our thermoformed part which will be used for the packing of our yo-yo.

• • Custom case molded over single mold

  • Single piece

Those are all the updates at the moment, but after the Yo-yo design review (Oct. 17th) we will be updating on any changes to this current design.
