Fender Design

FENDER:

A fender is the curved portion of the car's body that sits over and houses the wheels

The purpose of a fender is pretty simple. Its purpose is to keep mud, rocks, and other road debris from being thrown around by the tires. In other words, the fender is a housing for the wheels that keeps road debris contained. If there was nothing covering the wheels, all kinds of debris would be kicked up by the rotating tires.

The fender not only protects your car from sustaining damage from road debris but it prevents this debris from being thrown up at other vehicles on the road. This is why vehicles with large, oversized tires are often required by law to install fender flares.

Fenders are also able to absorb impact from minor collisions.

FENDER DESIGN:

Things to remember:

• Around a mounting point, plane or flat surface (surface with no curvature) should exists for about diameter of 20mm from mounting hole center.

FENDER MOUNTINGS:

1. DRIP:

These mountings are connected to the engine compartment

2. SILL:

It is the bottommost mounting point for the fender.

3. BUMPER MOUNTING:

The bumper will be fitted onto this mounting.

4. A- PILLAR MOUNTING:

It mounts inside A-pillar panel.

5. FLASH MOUNTING:

The image on right shows the FLASH (black fibre part) which protects engine bay from outside dust and foreign particles.

FENDER MANUFACTURING PROCESSES:

Drawing: In drawing, the sheet metal is forced against a die that has been cut into the three-dimensional, often curved shape that the sheet metal is to take on.

In effect, the die is used as a mold for the metal. This technique can produce relatively complex shapes. Once again, pressure is applied to the workpiece using a hydraulically or mechanically operated punch.

Lubricant can be used to make the metal slide more smoothly against the die, avoiding the possibility of wrinkling. Alternatively, the wrinkled edges can be trimmed from the metal in a separate operation.

Stamping: In stamping, a device called a stamping press is used with a series of dies to cut and form metal into various shapes. This is commonly used to make auto parts such as hubcaps and fenders.
