BUMPER

Automotive Bumper | Siemens UG NX | Plastic Domain Design

This Automotive Bumper was designed in Siemens UG NX using the Plastic Domain workflow. The design process began with the given Class-A surface, which was validated for surface quality and continuity. A proper tooling axis was created based on draft analysis, and using this reference, Class-B and Class-C surfaces were generated to achieve the required wall thickness and smooth connectivity. These surfaces were then combined into a closed volume, ensuring solid conversion. A detailed draft analysis was carried out to confirm tooling feasibility, and a parting line was defined for mold separation. The project demonstrates my ability to apply plastic product design standards in Siemens NX to create tooling-feasible exterior trim components such as bumpers.

🔹 Design Considerations

Maintained uniform wall thickness for injection molding.

Applied correct draft angles for mold release.

Ensured Class-A to B and C surface connectivity with smooth transitions.

Created tooling axis and parting line for manufacturability.

Converted surfaces into a closed volume to validate the solid model.
