About Us
Henan zhongyuan Heavy Forging Co.,Ltd(HHF) founded in 2006, the company has accumulated nearly 20 years of deep professional experience and technological expertise in the field of heavy-duty forging.
The factory covers an area of approximately 150 mu (about 100,000 square meters). The company operates 3 large-scale open-die forging production lines (with core equipment including 10,000-ton hydraulic presses), 2 modern die forging production lines, along with supporting large-scale CNC machining centers, heat treatment lines, and a well-equipped National Class II laboratory. The company has an annual production capacity of 50,000 tons for large open-die and die forgings (with the ability to produce single pieces weighing over 30 tons).
The company currently employs nearly 500 people, including a dedicated R&D team of over 50 professionals, consisting of senior engineers and technical experts focused on developing new processes, materials, and technological innovations.
Its quality management system is backed by multiple certifications, including the American API Q1 standard, API 7-1 licensing for drill stabilizers and drill collars, CSSC system approval, and international accreditations such as ISO 9001:2008 and ISO/TS 29001.
Our commitment to quality, innovation, and unwavering product integrity is physically embodied in our state-of-the-art Physical and Chemical Analysis Laboratory. This facility is not merely a support unit but a cornerstone of our Research & Development and quality assurance processes. Constructed, equipped, and operated in strict accordance with the stringent requirements of the National Grade 2 Laboratory Standards, it represents a significant investment in technical capability, ensuring that every component we manufacture—from a standard drill collar to a mission-critical turbine shaft—meets or exceeds the most demanding international specifications and customer-defined parameters.
The laboratory's comprehensive suite of testing and analysis services is designed to deconstruct and understand material performance at the most fundamental level. It provides empirical, data-driven validation for our production processes and final products. Our capabilities are systematically segmented to evaluate mechanical properties, structural characteristics, chemical composition, and specialized functional performance, forming a holistic quality verification ecosystem.
HHF is proud to be China's pioneering enterprise in the development and mass production of 6-rib under-reaming drill stabilizers. This breakthrough innovation represents a significant advancement in downhole drilling technology, combining precision engineering with durable design to enhance operational efficiency and tool reliability in complex geological formations.
As a cornerstone of our commitment to excellence, HHF exclusively sources raw materials from China's most renowned and reliable steel mills. This ensures consistent material integrity and superior metallurgical properties from the outset. Our manufacturing process integrates state-of-the-art forging techniques, advanced heat treatment technologies, and precision CNC finishing machining. Each stage is meticulously controlled to produce under-reaming drill stabilizers that not only meet but consistently exceed industry standards, establishing HHF as a benchmark for quality in the Chinese drilling tool sector.
