Originally recognized as Hunan Zhuangyuan Geological Equipment Co., Ltd., our esteemed company was once part of the distinguished Hunan Provincial Institute of Geophysics and Geochemistry. Our origins trace back to the 409 team mechanical repair workshop. In 1989, we proudly established the 409 Repair Factory, and by 1992, the dynamic Diamond Products Research Institute was born. Fast forward to 2003, Zhuangyuan (Group) Company came into existence, encompassing both Hunan Zhuangyuan Diamond Products Co., Ltd. and Hunan Zhuangyuan Geological Equipment Co., Ltd. Advancing into 2016, we partnered with Hunan Hongyu Water Resources and Hydropower (Group) Co., Ltd. to form Hunan Yuanyu Exploration Technology Development Co., Ltd. As a prestigious national high-tech enterprise, we specialize in the art of design, production, research, and the innovative development of geological equipment, including drilling rigs, exceptional drilling tools, advanced diamond drill bits, and cutting-edge centralized slurry injection systems. Notably, our pioneering "centralized slurry grouting system" has been honored by being on the first recommended list for emergency equipment procurement in Hunan Province.
In recent years, our company has garnered a plethora of accolades. The esteemed "Zhuangyuan" brand has repeatedly achieved the distinction of "Famous Trademark of Hunan Province." We have been recognized as the "Hunan Province Contract Abiding and Creditworthy Unit" and celebrated as the "Hunan Province Integrity Construction Demonstration Unit" multiple times. We are proud to have been awarded the prestigious title of "National High-Tech Enterprise" in 2021, a testament to our commitment to excellence and innovation.
Our company places unparalleled importance on technological innovation, boasting an impressive portfolio of over 10 patents. We have forged enduring collaborations with the esteemed China University of Geosciences (Wuhan) and Central South University, positioning ourselves as the proud industry-university research base of China University of Geosciences (Wuhan). Moreover, our collaborative efforts with the Guangzhou Institute of Geochemistry of the Chinese Academy of Sciences have resulted in the highly acclaimed marine shallow sampling drilling rig, earning exceptional praise and recognition from our valued users.
