Our Team and Achievements
Our Team and Achievements
With over two decades of leadership in high-precision injection mold design, Edward Lai has redefined excellence across the electronics, automotive, and healthcare industries. As the visionary founder and Managing Director of Defini, and former Chairman of the Hong Kong Mold and Die Council (1993–2003), Lai’s technical ingenuity and strategic acumen have shaped global manufacturing standards.
In 2008, Lai merged his engineering expertise with a passion for underwater exploration to launch Nauticam, a transformative venture that revolutionized underwater imaging. Leveraging mastery of CNC machining, optical design systems, and advanced plastic injection molding, Nauticam pioneered camera housings that seamlessly integrate precision engineering with user-centric functionality. Designed by an avid diver and photographer, these solutions addressed critical needs in existing equipment, propelling Nauticam to become the world’s foremost brand in underwater imaging technology.
Under Lai’s leadership, Nauticam’s multidisciplinary team has achieved extraordinary milestones, including nine international patents and three Red Dot Design Awards, alongside Hong Kong’s prestigious Consumer Product Design Grand Award. Their innovations—ranging from rugged housings to groundbreaking underwater optics—empower filmmakers and photographers to capture previously unattainable imagery. This engineering prowess has cemented Nauticam as the trusted partner behind award-winning documentaries like My Octopus Teacher and Planet Earth, as well as major cinematic productions, earning acclaim from directors, cinematographers, and creators globally.
