Mass Manufacturing, 2019


2.008 - Design and Manufacturing II is an MIT course where students study and implement manufacturing methods. Each team designs a unique yoyo, produces tooling for injection molding and thermoforming, and operates the equipment in order to mass produce 50 units within product specifications.

Our team created a yoyo with the appearance of two steamed bao trays, which could be opened to reveal dumplings inside. The yoyo models, thermoform dies, and injection molds were collaboratively designed in Fusion360. The tooling was produced using SLA 3D printers and 3-axis CNC machines.

Trial and error provided us with hands-on learning for topics such as cycle times, press fits, draw ratios, tool engagement, thermal shrinkage, and process capability. In addition to the aforementioned methods, this course also covered design for assembly, variation, quality control, process planning, factory design, metal forming, and microfabrication.
