Week 12- Final project

Aim :-

Creation of CAD model considering following inputs as like in OEM and tier1 companies

a) Class A surface
b) Nominal thickness : Refer master sections
c) Attachment strategy :

Find a attachment strategy for the door panel complete work.

Use Push pin with Dog house for Lower substrate – Door panel attachment

Use heat stakes for part to part attachment

Objective: The project deals with the explanation of method followed to develop door trim inner panel. In this with the given Class-A surface, Class-B surface and Class-C surface were created along with the tooling axis. Other attachment features were also created for assembly of the different components of door trim.

Methodology:

The methodology of the project is explained here:
1. Class-A suface was extracted from the given surface.
2. Tooling Axis were created of the individual component.
3. Class-B and Class-C surface were created with the OEM guidelines.
4. Formed Solid body from the closed surface.
5. Engineering features were created for attachment.
6. Draft analyses of each component was performed to check the manufacturing feasibility.

Introduction:

The inner door panel is an aesthetic and functional component in a car, it is the interface between the car interior and the inner working of door. Inner door panel usually consists of armrest, map pocket, bottle holder, handle bar, other switches, upper and lower substrate, storage compartments, convenience (puddle) lights and locking mechanism. Nowdays door panel is made of plastic material like polypropylene, ABS etc. which helps in making lightweight and complicated shapes of door panels.

The manufacuring Process of plastic door panel is called Injection molding. In this manufacturing process the heated molten plastic material is injected into the mould between core and cavity and cooled down to form a solid plastic component
