2. Studying available packaging space
3. Selecting an appropriate plastic material
4. Creating the initial CAD model
5. Developing Class A, B and C surfaces where required
6. Adding engineering features such as ribs, bosses and mounting points
7. Applying draft and tooling considerations
8. Checking injection molding feasibility
9. Performing assembly and clearance checks
10. Preparing engineering drawings
11. Supporting prototype and validation activities
12. Making design changes based on manufacturing and testing feedback

This combination of design and manufacturing knowledge makes plastic product design different from basic CAD modeling.
