Our esteemed company, originally known as Hunan Zhuangyuan Geological Equipment Co., Ltd., proudly traces its roots to the prestigious Hunan Provincial Institute of Geophysics and Geochemistry. Emerging from the 409 team mechanical repair workshop, we officially became 409 Repair Factory in 1989 and further evolved with the establishment of the Diamond Products Research Institute in 1992. By 2003, Zhuangyuan (Group) Company was formed, encompassing both Hunan Zhuangyuan Diamond Products Co., Ltd. and Hunan Zhuangyuan Geological Equipment Co., Ltd. Our metamorphosis continued, leading to the creation of Hunan Yuanyu Exploration Technology Development Co., Ltd. in 2016, through a strategic partnership with Hunan Hongyu Water Resources and Hydropower (Group) Co., Ltd. As a distinguished national high-tech enterprise, we shine in the realms of design, production, scientific exploration, and operational excellence in geological equipment, including advanced drilling rigs, innovative drilling tools, high-performance diamond drill bits, and centralized slurry injection equipment. In emergency equipment, our pioneering "centralized slurry grouting system" stands out, having been selected for the elite first batch of recommended emergency equipment procurement list in Hunan Province.
In recent years, our illustrious company has been honored with numerous accolades: our renowned "Zhuangyuan" brand has repeatedly earned the prestigious title of "Famous Trademark of Hunan Province." We've been lauded as a "Hunan Province Contract Abiding and Creditworthy Unit" and a "Hunan Province Integrity Construction Demonstration Unit" on multiple occasions. In 2021, we proudly received the distinguished recognition as a "National High-Tech Enterprise."
Our company places a premium on technological innovation, boasting over 10 groundbreaking patents. We maintain strong collaborative ties with the esteemed China University of Geosciences (Wuhan) and Central South University, serving as an industry-university research base for the former. Our collaborative efforts with the Guangzhou Institute of Geochemistry, part of the Chinese Academy of Sciences, led to the development of an exceptional marine shallow sampling drilling rig, widely acclaimed by users for its superior performance.
