INDUSTRIAL RESEARCH PARTNERSHIP/COLLABORATION

Industry Project title Salient achievements
Titan Company Ltd, Hosur (Tanishq) Hardening of 22k and 24 K gold We have developed a technology for improving the hardness of 22k gold for weight saving and high strength in cast and hand-made jewelleries. The technology has been transferred to Titan for the production of jewellery with the hard gold. First pilot scale was launched on 28th October 2016 on Danteras day. The second pilot scale was launched on 22 March 2018. Presently several designs of machine made bangle have been made and are available for sale in Tanishq Jewelleries in several flagship boutiques around India. The PI has realized this entire prestigious project in a record time of 20 months, which includes laboratory experiments, series of industrial trials and production by Titan company ltd. The technology has been patented jointly by Titan and SRM and it is owned by both the parties.
Titan Company Ltd, Hosur (Watches) High strength lead free and leaded brass The purpose of increasing the hardness and strength in brass in order to minimize handling defects during manufacturing (polishing and plating) and also to improve the scratch and wear resistance at the user end. The project kick started on April 2018 and PI has delivered the proof of concept to the industry within five months on August 2018. The industry made pilot scale production and evaluated the property enhancement. As the way forward rigorous industrial trials are being conducted and “WATCH CASES” made using the hard lead free brass will be launched in the market in pilot scale on March 2019. Joint patent filed.
