Our Story of Growth
Yingdige: Our Journey – From Seedling to Global Partner in Underwater Technology
We are a subsidiary of HaiSi (Langfang) Technology Co., Ltd. Focusing on the underwater technology field, we have been deeply engaged in watertight connection and marine exploration. Our goal is to become a reliable partner for global customers. Since our establishment in 2018, we started as an international connector brand agent and quickly completed the transformation to technological research and development and system integration. From 2020 to 2023, we gradually expanded our product range, explored the global market, and gained recognition from global customers through high-quality products. Meanwhile, we have established a professional R&D, production and service system, steadily moving towards large-scale and global development.
Core Positioning
Focus on underwater technology, deeply engage in watertight connections and marine exploration fields, and strive to become a reliable partner for global customers.
2018-2019: Seedling Launch · Strategic Transformation
On November 30, 2018, we officially established our company. Initially, we served as the global agent for a well-known connector brand in the United States, accumulating rich global industry experience in the underwater field. From the end of 2018 to the beginning of 2019, we optimized our business scope and completed the transformation from "simple trade" to "technical research and development + system integration". We identified watertight connectors, underwater cameras, and marine buoys as our core products and initiated independent research and development.
