Our esteemed company, previously known as Hunan Zhuangyuan Geological Equipment Co., Ltd., originated from the prestigious Hunan Provincial Institute of Geophysics and Geochemistry. It evolved from the eminent 409 team mechanical repair workshop, leading to the inception of the 409 Repair Factory in 1989. The Diamond Products Research Institute followed in 1992, paving the way for the establishment of Zhuangyuan (Group) Company in 2003, encompassing Hunan Zhuangyuan Diamond Products Co., Ltd. and Hunan Zhuangyuan Geological Equipment Co., Ltd. In 2016, a new era began with the formation of Hunan Yuanyu Exploration Technology Development Co., Ltd., in collaboration with Hunan Hongyu Water Resources and Hydropower (Group) Co., Ltd. As a national high-tech enterprise, we excel in the design, production, scientific research, development, and operation services of advanced geological equipment, including drilling rigs, drilling tools, diamond drill bits, and centralized slurry injection equipment. Our innovative 'centralized slurry grouting system' has been honored in the inaugural recommended emergency equipment procurement list in Hunan Province.
