Week 8 - Challenge 2 - Base Bracket Design

• When developing parts for plastic injection molding, applying a draft (or a taper) to the faces of the part is critical to improving the moldability of your part. Without it, parts run the risk of poor cosmetic finishes and may bend, break, or warp due to molding stresses caused by the plastic cooling.

For draft analysis of the BASE bracket, first, we have to choose the right tooling axis for that we have first created a dummy tooling axis at the center of the hole which was in the class A surface.

then we have created the real tooling axis at the bisection point of two class A surfaces which were at some angle with the dummy axis.

after creating the tooling axis we have done the different analysis

• angle of the surface to the tooling axis
