Injection Molded Banana

Over the course of 10 weeks I worked with a team of four people to design and produce a 3rd grader inspired injection molded toy. We decided to create a banana with shoes and a hat for our design. To make the banana we made a CAD model, used the CAD model to create molds in NX and CAM them, CNC milled the molds, and injection molded the bananas to create the final toy.

The CAD model is comprised of four parts. Two banana halves, the hat and the shoes. I designed the banana and assured the CAD of the two halves were manufacturable.

Four molds were created to injection mold the 4 parts. The CNC processes involved up to five tools. I CAMed the molds and operated the CNC mill for each mold.

20 bananas were injection molded. To do this, parameters such as time, pressure and temperature were adjusted to create parts with the least flaws possible.
