Objective:
● Design Outer Panel with the Hem
● Develop the Inner Panel
● Develop all the Necessary Reinforcements
● Mirror and position the Hinge & Striker
● Provide Mastic Data
● Provide the required Emboss definition
● Develop a detailed Report for the Mastic position and
Embossed you have placed

Outer Panel with the Hem
Hem is provided to the uppe
provide the better grip between inner panel and outer panel of
hood
The clearance between
about 0.2 mm
Outer Panel with the Hem
Hem is provided to the upper panel of the hood at the corner to
provide the better grip between inner panel and outer panel of
The clearance between Hem and inner panel should be near

4. Hood Design
Inner panel designer so as t
view for the customer and one is to
of them by considering engineering
design.
It should have some feature like emboss at the hinge point
provides the better strength to the inner panel of hood.
Inner Panel
panel designer so as to appear better visualization, better
view for the customer and one is to meet customer requirement
dering engineering fundamental behind

behind hood
should have some feature like emboss at the hinge point which
better strength to the inner panel of hood.

Positioning the Hinge & Striker
Positioning of hinge and striker such that there is perfect tangent
relation of latch and trajectory of hood movement if it does not
satisfy this condition there is problem occurs during engagement
of the hood with engine compartment, then we have to adjus
hinge and latch position to achieve this relation

Mastic data should be provided in between hood upper panel and
inner panel to achieve better NVH
to maintain the upper hood surface
Generally mastic diameter should be about 80mm

Mastic Data
Mastic data should be provided in between hood upper panel and
inner panel to achieve better NVH Range, to avoid the spot
to maintain the upper hood surface regularity.
Generally mastic diameter should be about 80mm which
strengthen diameter of the mastic rubber.
Dotted circle shown in figure indicate mastic position

Mastic data should be provided in between hood upper panel and

The required Emboss definition
Emboss is created such that when force induced in middle of
the hood which directly transmitted to the hinge point to
provide better safety.
the force transmission
which causes serious damage
Figure shows the emboss and force
transmission/distribution in inner panel.
The required Emboss definition
Emboss is created such that when force induced in middle of
the hood which directly transmitted to the hinge point to
provide better safety. If this type of emboss not provided
transmission towards the centre of hood or vehicle
auses serious damage,

transmission/distribution in inner panel.
