The design of injection molded parts was a course I followed at Hogeschool Rotterdam.
The assignment was to design an injection mold for a plastic bottom shell of a remote control.
In the cross-section below, the structure of the mold can clearly be seen.
Furthermore, a simulation was run, to check whether the part was actually producible and if the injection point was in the right location.
The images below show the filling time and the sink marks.
