Hunan Yuanyu Exploration Technology Development Co., Ltd
Our illustrious journey began as Hunan Zhuangyuan Geological Equipment Co., Ltd., originally a proud part of the Hunan Provincial Institute of Geophysics and Geochemistry. Rising from the roots of the 409 team mechanical repair workshop, we established the 409 Repair Factory in 1989. By 1992, we had further evolved with the inception of the Diamond Products Research Institute. In a significant leap forward, Zhuangyuan (Group) Company was formed in 2003, comprising Hunan Zhuangyuan Diamond Products Co., Ltd. and Hunan Zhuangyuan Geological Equipment Co., Ltd. Our transformative milestone came in 2016, when the esteemed Hunan Yuanyu Exploration Technology Development Co., Ltd. was born from a powerful alliance with Hunan Hongyu Water Resources and Hydropower (Group) Co., Ltd. We are proud to be recognized as a national high-tech enterprise, excelling in the design, production, research, and development of cutting-edge geological equipment including drilling rigs, sophisticated drilling tools, diamond drill bits, and innovative centralized slurry injection equipment. Notably, our pioneering 'centralized slurry grouting system' stands distinguished, having been selected for the inaugural procurement list of recommended emergency equipment in Hunan Province.
In recent years, we have basked in accolades and recognition, receiving numerous prestigious awards. Our revered 'Zhuangyuan' brand has been crowned with the title 'Famous Trademark of Hunan Province' on multiple occasions. We pride ourselves on being recognized as a 'Hunan Province Contract Abiding and Creditworthy Unit,' as well as a 'Hunan Province Integrity Construction Demonstration Unit,' demonstrating our steadfast commitment to excellence and integrity. The pinnacle of our achievements came in 2021, when we were honored as a 'National High-Tech Enterprise,' affirming our position at the forefront of innovation.
Deeply committed to technological innovation, we have acquired over 10 patents, showcasing our relentless pursuit of advancement. We sustain vibrant collaborations with esteemed institutions like China University of Geosciences (Wuhan) and Central South University, proudly serving as the industry-university research base for China University of Geosciences (Wuhan). Our joint endeavor with the Guangzhou Institute of Geochemistry of the Chinese Academy of Sciences has birthed the remarkable marine shallow sampling drilling rig, earning widespread acclaim and cementing our reputation for excellence.
