Day 2: Design of an Injection Molded Component with Integrated Features

Justify material selection for an automotive grab handle based on functional and manufacturing requirements.

Develop the modeling sequence for a grab handle incorporating a cantilever snap-fit and a screw boss using CATIA Part Design logic.

Apply appropriate wall thickness, draft angles, and fillet radii to the grab handle based on injection molding design rules.

Perform a DFM review on the grab handle, identifying moldability issues related to the base part and attachment features.

Conduct a DFMEA on the grab handle, identifying potential failure modes related to molding, assembly, and in-service use.

Produce a 2D drawing of the grab handle with a complete datum scheme and GD&T callouts for critical features.
