The major project for our Design & Manufacturing class was to make an injection molded yo-yo. Our group decided to make a soda/beer can shaped yo-yo because we wanted our yo-yo to be wide and stable. We designed the yo-yo, machined molds, and did runs of injections to optimize the machine settings for mass production. After a mass production run we gathered statistics on the variation of our key dimensions to evaluate the performance of our chosen machine settings.
