Geometric began as part of the Godrej group, one of the oldest and largest business

conglomerates of India. Founded in 1897, the Godrej group has interests in engineering and

consumer products, and is known for its philanthropy, besides being recognized for its values

of fair, transparent, and ethical dealings.

Godrej & Boyce Co. Ltd. is one of the founder promoters of Geometric besides being the

largest share-holder (30.26%). It is one of the largest privately-held diversified industrial

conglomerations in India with a combined sales of about USD 2.5 billion for the year ended

Key Customer Concerns

Ensuring quality

Controlling production

costs

Minimizing time to market

• Higher delays due to rework

• Lower productivity

• Higher costs due to scrap• Expensive tooling

• Quality problems due to inexperienced engineers• Manufacturing defects

Improving Innovation

• Lesser new product developments

7


Design to Production – Traditional Method and Challenges

Background

• Issues related to product design go undetected

until manufacturing trials – expensive to make

product changes once released to production

• Many designers may not have knowledge of

manufacturing rules and best practices -

resulting in slower product development cycles,

increased ECO/ECNs, significant material waste

and lower production yields

• To prevent initial designs from becoming a trial

and error process, some manufacturing

knowledge-based assistance is necessary.

70% of the final product cost is determined during the design stage

Implementing DFM

Traditional Method of handling DFM Reviews

• Maintaining DFM checklists, guidelines-handbooks

• Periodic training of designers

• Manual reviews of design (by self / peers / seniors)

• Consultations with manufacturing experts

Problems

• Manual reviews are time consuming

• Inconsistent design quality

• Need for proximity between design and

manufacturing engineers

Summary : DFMPro Benefits

Reduces overall cycle time, scrap and rework

Detects manufacturing issues in the design stage

Captures ‘lessons learnt’ and educate new engineers

Supports continuous process improvement

Facilitates training of design engineers


Customers Speak: Rockwell Automation

“Injection molding parts are typically complex and difficult to check manually.

Compared to earlier manual methods of checking parts for draft angles, wall

thickness and undercuts; DFMPro quickly and accurately identifies such

regions. It serves the direct purpose of identifying manufacturability problems

right at the design stage and helps reduce design iterations.

It is an easy to use tool which significantly helped us to reduce our part

checking time by almost 60% while ensuring robust quality of design.”

Randy Scherger

Senior Tool Designer

Rockwell Automation


Customers Speak: Sulzer

“Using DFMPro, we were able to reduce our time for checking the

product design from the manufacturing feasibility point of view by

approximately 90% w.r.t manual checking. The net reduction in total

time for checking of product design by using DFMPro software is

approximately 15%”

Amol Mane

Manager, Engineering Dept.

Sulzer India Ltd


“Geometric Limited has quick, test-driven analysis tools – DFMPro and

GeomCaliper. They are indeed simply integrated, intuitive and seamless

in Creo ( Pro/Engineer).

The results of tool aid us in improving our design and reducing issues

in downstream”
