Week 9 - Challenge 1 - Base Bracket Design
BASE BRACKET:
A supporting component in mechanical or architectural designs that serves as a mounting point or foundation for other parts.
Steps involved in Designing a base bracket using the Class A surface:
- Creation of Tooling Axis
- Draft Analysis on Class A surface
- Creation of Class B Surface
- Creation of Class C Surface
- Final Base bracket surface model
- Draft analysis to check the surface model
- Creation of part body model from surface model
- Draft analysis on the final part body
Thickness of the Plastic Part is 2.5mm.
Detail report on the creation of Tooling Axis and Draft analysis:
The draft tooling axis is a crucial concept in plastic part design and mold manufacturing. It refers to the direction in which the mold opens and closes, ensuring that the part can be easily ejected without defects.
Tooling Axis creation:
- Extract the layer border using the intersect option via choosing a plane.
- create lines on the tapered surface borders and create the bisecting line using those lines to get the tooling axis.
- Ensure to create the tooling axis such that the class A surface passes the draft analysis.
Draft analysis is a crucial step in plastic part design and mold manufacturing. It ensures that a part can be easily ejected from the mold without defects by verifying the draft angles.
Draft analysis:
- Open the draft analysis in the part design workbench.
- Place and lock the compass on the tooling axis and click on the surface to see the colour coding of the analysis. The colour coding used by me is as shown in the figure.
- Check if the Class A and Class C are passing the analysis else draft has to be cross checked once again.

Hence the designed Bass Bracket model passes the draft analysis with no defects.
