Surface Design-Door Switch Bezel
Aim: Development of inner trim- Door Switch Bezel
Input: Clas A surface Generated using software called Alias
Objective:
- Create tooling axis by following the OEM standard
- Class A to Class B Surface Creation
- Part Thickness : 2.5 mm
- Draft analysis report
Class A Surface is the outer skin of the product which is purely an aesthetic model with no engineering properties involved
The input Class A Surface of bezel trim is shown below:

TOOLING AXIS:
Tooling should be such that to ease of maufacturing if it is done by mold of tool & die method. The given Class A input is analyzed to envision the part to manufacture and Tooling axis or Tooling Direction. Thus tooling direction determines Mold seperation and also becomes vital in developing the plastic product drafted to desired nominal angle for feasible clearance and ejection of final part from the mold.
Class B is nothing but the offsetted surface from class A by taking consideration of thickness into the part. Which is not deals with styling surface which directly exposed to customer hands.
Draft analysis:

RESULT:
- The Green color is drafted walls above 2.9 degree
- The Blue color is drafted walls from 0-2.9 degree
- The red surfaces are negative degree
Conclusion:
Acoording to draft analysis report switch bezel is OK to manufacture. Analysis shows that it is good for the draft angle 2.9 degree.
