H e m a G r o u p EXISTING CYLINDER HEAD COVER

NEW CONCEPT OF

CYLINDER HEAD COVER

IMP POINTS:

- MODELING OF CYLINDER HEAD COVER USINGEXISTING DESIGN.

- THE EXISTING DESIGN HAS A OPENING ON

SINGLE/ONE SIDE

- MODIFICATION WAS DONE TO MAKE THE

OPENING ON BOTH SIDES CONSIDERING

“Ease of Maintenance”

- DURING THE MODIIFCATION PROCESS IT WASENSURED THAT THE “ MOVING COMPONENTS”

SHOULD NOT OVERLAP

- NO INTERFERENCE SHOULD OCCUR.

Projects: Arm rest5/11/2011 www.hemaengineering.com

Scope :

• Alternative design for current arm rest (sheet metal).

• VA/VE to focus on framework, foams and insert

• Reduction of 20% material Reduction of 20% labor cost.

Output from Hema :

VA/VE activity conducted at Hema gave the following results:

• Current design modified from sheet metal to plastic

injection molding eliminating the need for external foam.

• Percentage reduction – 15 %

Scope :

Design modification of current arm rest to

incorporate aluminum insert into mould.
