Go-to-Manufacturing Report

Over the past week, senior squad has been working on our go-to-manufacturing report. We used the results from our Moldflow analysis, to scale up our CAD models by about 1.2% for each part, except for the antenna which had a higher shrinkage percentage of 2.7%. We then made CAD models for the molds for our injection molded parts, and their respective CAM toolpaths.

In parallel, we worked on a bill of materials for each stock material we would need for the entire manufacturing process, and we also drafted up a layout of our factory. Here are some of the key results:

Moldflow Analysis

Image
We recently used the Moldflow software to analyze our injection molded parts: Patrick, the base, the rock, and the antenna. The most useful information we received was the shrinkage: Base: 1.28% Rock: 1.20% Patrick: 1.28% Antenna: 2.67% We also gained important information on the cycle time, which we can use moving forward when working on our factory layout. If you are interested in seeing more of our results, you can check out our Moldflow report here: https://docs.google.com/document/d/1e6q5_iBeC9F7JpJ_XUnGs-icJlVAsYjP-zRTd4GQ9dk/edit?usp=sharing

Final Report

Image
We have reached the end of the semester, and would like to update everyone with our final report! Since our go-to-manufacturing report, we have focused heavily on designing a factory using the Tecnomatix software. We have five production lines making each part.  Using our agreed-upon parameters (explained in detail in the report) we were able to make 1,043,864 yo-yo's in one year! After looking at our cost analysis we would need to make around 700,000 yo-yos to break-even, and have decided to charge $10 per yo-yo to make a decent profit. However, we have strategies for reducing cost, including an infinite buffer, moving to another country with lower wages, and pursuing automation.

Looking Back at the Design Review

Image
While it has been a while, we wanted to take a look back at our design review! The main goal of our yo-yo was to show Patrick Star living under his rock. Each of the two sides of the yo-yo would be Patrick living under that rock. In order to do this, we decided our yo-yo would be made of the following parts: We decided to injection mold every part except for Patrick, which will be thermoformed (this design choice has since changed, but this was our decision at the time of design review). In order to get a sense for what the yo-yo would look like, we 3D-printed one side of the yo-yo, and here is the result! For more on our design review, you can view our presentation here: https://docs.google.com/presentation/d/18DHTvW9kK-wbNYPmfx5LZZFfujo952XgDPKz3XcQQc4/edit?usp=sharing
