• Bumper mounting
• Drip mounting

Design data for fender

A-pillar mounting

The A -pillar is the structural pillar that combines the body to the roof. this make the sides of the windshield rest. front fenders are fastened to the A -pillar to form a robust structure.

Drip mounting

• It is the important mounting unit of the fender. It is connected with the engine compartment; therefore, the lot of design constraints are to be followed while designing the fender
• While designing the drip area we have to initially leave 200-300 mm for cowl top
• For placing the headlamp, we have to leave at least 150 mm at the front while designing the fender
• Cowl top part consists pf wiper motor and its instruments
• Two darts are added on the longer side of the drip area in order to provide the stiffness and adds strength to the part. This helps the fender to not to vibrate and impact the forces outside of the fender during motion of the vehicle.
• Embossing are provided on the mounting to strengthen them during fastening

Sill mounting

Sill is the panel directly below the bottom of the door supporting the floor and may be used to combine the floor and the body. The bottom end of the fender is mounted on the sill body for reinforcement of the fender panel, thus the sill mounting position is designed with holes and emboss. M5 fasteners are used to fix the fenders on the sill body.

Bumper mounting

Bumper mounting area is used to fix the plastic bumper to the fender with the help of the fastener.

Baffle mounting

Baffle mounting or mudguard are clip fit type of mounting on the inner side of the fender arch over the Tyre. it protects the car engine compartment and pedestrians from causing injuries from chip out debris on the road when the car is in motion. they are mounted on the fender using a special type of locking clips which are made up of plastics.
