Fender Design

Report

There are two main types of fenders: full-bumper type and half-bumper type. The full-bumper type fender is used when the front end of the bumper is integrated with the front bumper and headlamp casing. Half-bumper type fender is popular and used when the headlamp casing is independent and housed between the bumper and fender. Moreover, the half-bumper type fender helps reduce material waste (scrap) while manufacturing as two fenders can be produced in a single blanking.

A car fender (half-bumper type) has the following mounting points:

• Drip Area mounting: Where the fender meets the engine housing.
• A-pillar mounting: Where the fender attaches with the A-pillar.
• Sill mounting: The attachment with the floor/ sill of the car.
• Bumper mounting: Where the bumper and fender are attached.
• Baffle mounting: The baffle is fixed on these.

All mountings are done by fasteners like nuts and bolts, and screws.

Fenders are manufactured mostly using the Stamping process:
