COPPER ROTOR SUCCESS STORY IN THE FAR EAST
Small Indian Business Exceeds Expectations 
“About 10 years ago we learned of the advantages of copper rotors,” explained Mr. Akhtar Hussain G. Ajmearwala, owner and operator of Perfect Die Cast in Gujarat, India. “But, at that time, people believed that die casting copper rotors was not possible at all.” Determined to prove this belief wrong, Mr. Ajmearwala's father, the founder of Perfect Die Cast, made the company's first attempts to cast copper rotors. However, he was unsuccessful. Undaunted, the younger Mr. Ajmearwala built upon his father's research. “After years of slow trials I found your Web site, copper-motor-rotor.org. It gave us new confidence that it is possible to die cast rotors in copper,” he said.
When Mr. Ajmearwala contacted Dr. Cowie earlier this year, Dr. Cowie had been overseeing CDA's trials for over three years. “When Mr. Ajmearwala starting talking about problems with oxidation and cracking, I knew how CDA could help. We were having the same problems not so long ago,” Dr. Cowie explained. He said that Mr. Ajmearwala was missing three pieces to the copper motor rotor puzzle: a cover to prevent oxidation, a new high-temperature die material and an induction furnace to speed melting. “After a few trials and with kind help of CDA, we have succeeded in our project,” Mr. Ajmearwala explained.
