There are 2 types of fenders

1. Full Bumper Type
2. Half Bumper Type

Full Bumper Type

• Full Bumper Type is not used now a days because it requires large size of balnk to produce the part and it occupies more space.

Process of making fender

• The design of fender is made by same commant used for the diffrent area of mounting.

Mountings

1. Drip Mounting Area
2. Sill Mounting Area
3. A-Pillar Mounting Area
4. Bumper Mounting Area
5. Baffle or Linear Mounting Area

1. Drip Mounting Area

• The drip area would be recognizable fom the opening between Hood and Fender.
• This mounting is attached to the engine compartment of the car.
• A min 150mm distance is kept from the front side and a distance 300mm or less can be kept on the rear side .
• This is to avoid the springback during the manufacturing . the edge of the mounting should atleast 10mm away from any nearby component in the engine.
• The drip area should be less than 40mm.
• The embosess that are created on the drip mounting should be flat with respect to the curvature.

2.Sill Mounting Area

• This is palced basically at the botom of the fender. The mounting part is created such that it firmly fits to the sill.
• The embosess that are created on the drip mounting should be flat with respect to the curvature.

3. A-Pillar Mounting Area

• A-pillar mounting is a vertical support on a vehicle.
• It holds the windshield set up and just downside to the A-pillar fender is mounted to hold the position.

4.Bumper Mounting Area

• It is placed at the front side of the fender,the bumper mount area of fender, mounts on the chassis to hold the position.
• Since Bumpers are mounted over the fender it is called Bumper Mounting Area.
