R a j k o t Rajkot is also the 22nd‐fastest‐growing city in the world. Cricket is the most famous sport in the city. Rajkot has produced cricketers such as K S Ranjitsinhji, Karsan Ghavri, Cheteshwar Pujara And SIR Ravindra Jadeja. Rajkot produce castings up to 70% of local diesel engine industry of India. There are about 500 foundry units in Rajkot. The majority of foundry units in Rajkot produce grey iron castings for the domestic market. A very small percentage (about 2%) of the foundry units export castings such as electric motor castings, automobile castings etc. Rajkot is famous for providing education to Mahatma Gandhi (Gandhiji), at the Alfred High School.

Generic view of present business scenario: Days are getting tougher and tougher for foundries …..applicable to all of us…. Schedules are not coming, customers are not lifting ordered castings and tremendous pressure to reduce prices from customers ends to unhealthy competition by fellow foundries Many foundries from 70% of workload have slipped to only 40-50% of the workload. And no ray of hope is seen in near future. We share our views how to survive in this difficult time, off course other than - reduce price and get competition’s share to remain at break-even.

USA Post World War I in 1918 Two of the most important new technologies were automobiles and radio. Plus One more , that was the motion picture. Technology made it possible for millions of people to improve their lives. It also caused great changes in American society.

USA Post World War II in 1945 The invention of air conditioning, the development of "Sun Belt" cities such as Houston, Atlanta, Miami, and Phoenix in the southern and southwestern states. Shopping centers multiplied, rising from eight at the end of World War II to 3,840 in 1960. Many industries soon followed, leaving cities for less crowded sites.

USA Post World War 3 USA Post Cold War – often dated from 1945-1991 The Cold War was so named as it never had any direct military action. Huge investment by Federal Govt. & Private Investors in R&D i.e. The Production of Knowledge boomed.

Cold War = Virtual War / No Physical War Let treat this –ve growth as virtual war!

Sustainable Technology through Innovation & Policy Initiative


Understanding the Challenges


CREATE AND EMBRACE SYSTEMS TO SUPPORT YOU

• If your systems and procedures are still not in place build them NOW! • If they exist, manage them dynamically to work for you!


Dream Decides Destiny! So let’s Dare 2 Dream. When it rains all birds occupy shelter but eagle is the only bird who avoids rain by flying above the cloud. Problem is common to all but attitude makes the difference.

Dream to Deliverables! Look for modular & manageable solutions Look for vendor who work with you for your comprehensive solution as your competent partner


Foundry, let’s focus on ROI Foundry Projects – Concentrate for competitive solutions Look for projects conceptualization, planning, detailed engineering & installation supervision Get support for Foundry Equipment manufacturing & installation, process support Procure Technical Solutions – Design process machines & handling equipment Select right vendor, who works as competent partner for you
