This past week has been exciting! We finalized our CAM for our 'B' mold and fabricated the first 'B's. 

We began the fabrication of the 'B's by varying parameters such as the shot size, the cooling size and the speed profile. We have created a spreadsheet with all this information including the 15 parts we fabricated. The information can be found here. 

We increased the gate size for our last injection mold and will now be edging a bit of the surface on the mold. Before achieving this part of the process, we noticed earlier that some of the outer pins were going too deep into the part (picture can be seen below- second one down). We started with all pins 5.812", then we moved the outside ones (not the 2 middle ones) one size down to 5.695". As for mounting the mold,  we had a total of .015” of shim.

Here are some pictures of the 'B's and of the mold on the injection molding machine.

Here's a picture of the mold in the injection molding machine as well as the calculations made for the ejector pins.

We have also been able to fabricate our thermoforming mold. See image below.
