Company History: The Journey of Suzhou Desisen Electronics
The Beginning: Arrival in Suzhou (2003)
In 2003, Dong ZuGang, affectionately known as Brother Gang, arrived in Suzhou with a vision to revolutionize non-destructive testing (NDT). Landing in the quaint Maple Bridge area, he was struck by Suzhou’s low-rise, traditional charm—far different from the towering skylines of Guangzhou or Shanghai. However, his early days were fraught with challenges. Unfamiliar with the city and underprepared, Dong faced difficulties finding a suitable manufacturing facility amidst widespread demolitions. On a rainy night, he scoured the city alone, determined to find a foothold for his dream.
A Helping Hand: Early Supporters
Dong’s perseverance was met with kindness from two pivotal figures:
-
The Maple Bridge Benefactor: A local wire manufacturer took Dong under his wing, arranging for his son to drive him around on a motorcycle—a luxury in an era when cars were rare. They explored areas like Guangfu, searching for a suitable workspace, laying the foundation for Dong’s early endeavors.
-
The Guangzhou Opportunity: A call from a stainless steel pipe factory in Guangzhou marked a turning point. Tasked with inspecting steel pipes, Dong took his first-ever flight, a nerve-wracking experience marked by the plane’s rumbling sounds. This project introduced him to the stainless steel pipe inspection field, sparking his passion for NDT innovation.
Growth and Milestones: Founding and Expansion
Founding Suzhou Desisen Electronics (2008)
With a background in NDT since 1994, Dong formally established Suzhou Desisen Electronics in 2008. The company began as a small operation focused on manufacturing NDT instruments, but its vision quickly expanded to include intelligent automation systems.
Four Relocations, Four Phases of Growth
The company’s journey is marked by four strategic relocations, each reflecting a leap in technology and scale:
-
Shilu (2008): Starting in a modest office, Suzhou Desisen focused on developing eddy current and ultrasonic testing instruments for small-scale applications.
-
Yagor, Industrial Park (3-4 years): The company upgraded its instruments with significant R&D investment, enhancing performance and reliability.
-
Nanhu Road (3-4 years): A pivotal shift occurred here, as Suzhou Desisen began developing automated and intelligent inspection systems, marking its transition to a broader market presence.
-
Songlin Town (Current): Now a leader in intelligent manufacturing, the company focuses on fully integrated automation equipment, serving diverse industries with cutting-edge solutions.
