Week 12- Final project

AIM - TO DESIGN THE A,B AND CSURFACE AND DESIGN OF ENGINEERING FEATURES AND ATTACHMENT STRATEGY FOR GIVEN A SURFACES OF LOWER DOOR TRIM.

ROLE OF PLASTIC INDUSTRY IN AUTOMOBILE-

MOST OF AUTOMOBILE INTERIOR AND SOME OF EXTERIOR COMPONENTS ARE MADE OF PLASTICS. AUTOMOBILE SECTOR IS THIRD MOST CONSUMER OF POLYMERS.

THE POLYMERS ARE USED IN AUTOMOBILES TO MAKE IT LIGHTWEIGHT, MORE AFFORDABLE AND FUEL EFFICIENT.

IN AN AUTOMOBILE VEHICLE 1/3 PARTS ARE MADE OF PLASTCS.

MOST OF AUTOMOILE PLASTIC COME FROM FOUR MAIN POLYMERS POLYPROPELENE,POLYURETHENE,POLYAMIDES AND PVC.

1) START WITH DESIGN OF TOOLING DIRECTION OF ALL 4 PARTS.

TOOLING DIRECTION IS THE DIRECTION IN WHICH THE PART IS GOING TO BE EJECTED. THE TOOLING DIRECTION IS DECIDED BY CONSIDERING SHAPE , UNDERCUTS TO AVOID THE SIDE CORING. MOST OF PART SHOULD BE EJECTED IN THE TOOLING DIRECTION.

2) AFTER DESIGN OF TOOLING AXIS APPLY DRAFT ANALYSIS TO CHECK THE TOOLING AXIS.

3)DESIGN B AND C SURFACE OF ALL FOUR COMPONENTS.AND MAKING ALL SOLID USING CLOSE SURFACE COMMAND.

4) DESIGN OF ENGINEERING FEATURES (HEAT STAKES, RIBS, LOCATORS AND DOG HOUSE.) AND FLANGES DESIGN FOR ASSEMBLY.

A) HETA STAKE

ON LOWER SUBSTRATE HAET STAKES ARE DESIGN TO ATTACH OTHER PARTS WITH IT.

B) FLANGES

FLANGES ARE DESIGNED TO ATTACH ALL TJH EPARTS WITH THE LOWER SUBSTRATE BY USING HEAT STAKES.

ALSO TO LOCATE THE PART USING LOCATORS.

C) DOG HOUSE DESIGN

DOG HOUSE HAS BEEN DESIGNED ON THR LOWER SUBSTRATE TO ATTACH PUSH CLIPS AND ASSEMBLY OF LOWER DOOR PANEL TO MAIN DOOR PANEL.

DRAFT ANALYSIS ON LOWER SUBSTRATE.

D) LOCATORS

LOCATORS ARE DESIGNED TO LOCATE THE PARTS.

E) PUSH CLIPS

5)FINAL ASSEMBLY

6) CONCLUSION-ALL THE SOLID BODY OF LOWER DOOR TRIM HAS BEEN DESIGNED SUCCESSFULLY WIT ALL NECESSARY ENGINEERING FEATURES.
