Injection Molded Toy

Computer-Aided Machining + Injection Molding Project

My team designed and manufactured an injection molded toy from a 4th grader's drawing of a whale.

Modeling the Toy​ & Mold in CAD


We created the toy as a a three-part assembly. We designed for injection molding constraints such as parting lines, wall thicknesses and surface curvatures.


Cavity Mold

Core Mold

Machining the Mold​


We minimized our mold's machining time by managing tool paths, adjusting surface roughnesses, and minimizing our tool counts. I machined the molds on a Haas vertical mill.

Injection Molding the Toy​


We injection molded 100 parts of our design. We optimized for injection molding parameters such as plastic plastic flow rate and injection pressure, to achieve a repeatable, quality surface finish.
