Week 9 - Challenge 3 - Bumper

AIM:-

To create the Bumper Design Plastic component through the given Class-A surface.

Objective:-

• To create a tooling direction.
• To perform draft analysis for given A-Surface and prepare the final close body.
• To design the Bumper plastic component by creating the B-Surface and C-Surface using the given Class-A surface.
• Take the Thickness of the component to be 3 mm.

Introduction:-

The input of the product designer is in the form of the A-class surface. The product designer's job is to create the B and C surfaces keeping all the aspects of the mold.

Class A Surface:-

1. Visible surface and aesthetic look.
2. Surface with textures.
3. Surfaces provided by customer(OEM).
4. Don't have any features like(rib, snap, bosses, etc) on class A surface.
5. Class A surface is made from scanned data with different software like alias etc.
6. Surfaces which are having CURVATURE CONTINUITY IS CALLED class-A.

DRAFT ANALYSIS OF A SURFACE:-

• Draft analysis of the surface is carried out to check if the surface or part can be manufactured with the required draft angle.
• Draft angle is needed for the component to clear the core and cavity surface as it would have shrunk towards the center while cooling.
• The draft angle in this design is 3 degrees. As A surface is a single surface there won't be much color difference.

Conclusion:-

Hence the given Class A surface was modeled with B and C Surfaces and it was attached below.
