Week 11 - Final project -Development of a Door Trim panel

OBJECTIVE

1. Development of a Door Trim panel

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

1. a) Class A surface
2. b) Nominal thickness : Refer master sections provided
3. 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

Output required:

• Create thickened part using master section for reference
• Create the mounting features as per design guidelines in the industry and with master sections
• Apply material details :
• Draft analysis & Tooling analysis
• Creation of parting lines and check tooling feasibility

PROCEDURE

1. Class A Surface

In Automotive industry there will be a dedicated team who will perform the aesthetic designing of various components including the whole vehicle. They will create various concept sketches after ideation. After that, they will also create a Class A surface of the product. This class A surface is then passed over to the NPD CAD team. They will initially inspect the Class A surface in order to check if the design is manufacturable or if it is following the engineering principles. If there are any issues about the design, they will contact the product design team and will ask to modify the Class A surface in order to solve the problem. Here I received the Class A surface as shown below.

Class A surface input

Plastic Parts:

1. Map pocket - upper part
2. Map pocket - lower part
3. Armrest split parts
4. Lower substrate
