Inspired by the challenging working conditions in the diamond industry, Dr. Arvind Patel applied his experience with laser technology from his time at ISRO to the diamond sector. He is credited with innovating technologies such as the Laser Bruiting Machine with Fiber Laser, which reduces operating costs by 1/20th, and the early integration of AI, ANN, and IoT, which were not widely known at the time. Dr. Patel is also a strong advocate for the “Make in India” and “Atmanirbhar Bharat” (Self-Reliant India) initiatives. He believes in developing in-house skills and creating a highly skilled workforce that can contribute to the Indian economy. This dedication to local talent development is a cornerstone of SLTL’s operations and has earned Dr. Patel and his company numerous accolades. He has received over 33 national and international awards and holds more than 29 patents.
Additionally, new WLG Technology represents a significant advancement in diamond processing. This cutting-edge technology enables the precise cutting of diamonds with parallel kerf (no V-shape), ensuring greater accuracy and quality in diamond shaping. The WLG Technology not only enhances the efficiency of the cutting process but also minimizes material wastage, thereby providing a more sustainable solution for the diamond industry. Moreover, this technology ensures unparalleled accuracy, enabling reliable, excellent cuts free from heat-related damage. This innovation underscores SLTL Group’s commitment to pushing the boundaries of laser technology and maintaining its leadership position in the global market.
