From an early age, I was captivated by the dream of becoming a scientist and found great joy in hands-on problem-solving. As China entered a period of rapid development, I became increasingly aware of the transformative power of technological innovation and efficient solutions in advancing the manufacturing sector.
Determined to pursue a life beyond the ordinary, I followed my passion with clear intent. After earning my Ph.D. from South China University of Technology ( One of China's top technical university.), and receiving systematic, professional training, I began my career at the Chinese Academy of Sciences. In 2005, I transitioned to a role at Guangzhou Normal University of Technology, where I have remained actively engaged in research and education.
In 2007, amidst the booming growth of China’s manufacturing industry, I founded Dongguan Weldo Automatic Equipment Technology to address the challenges faced by labor-intensive industries, particularly in manual coloring processes. Our company specializes in fluid precision control automation solutions for the promotional product industry—such as precision enamel coloring for metal tags, badges, pins, and medals.
Driven by years of technical research and continuous client feedback, we expanded in 2009 into the high-end jewelry accessories sector by developing automated Jewelry diamond setting robot . With ongoing innovation and technical accumulation, my team and I successfully created an AI intelligent visual diamond stone bonding machine tailored for high-end jewelry applications. We later introduced AI-powered 3D laser scanning automatic diamond stone setting machine and intelligent visual jewelry enamel coloring machine with high precision eject system.
Today, we work closely with clients across the full spectrum of innovation—from R&D and design to equipment production and technical support—forming deeper, more integrated partnerships.
Our mission is to help clients streamline operations, enhance product quality, and gain a competitive edge in the market. In this era of rapid technological change, true success lies in pushing boundaries and turning vision into reality. At Weldo, we remain committed to advancing manufacturing innovation and helping every bold idea come to life.
