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).
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 takes it as its mission to promote the image of Chinese manufacturing, and always follows the quality policy of dddhhhstrive for perfection, manufacture high-quality machinery, pursue excellence, and create a first-class branddddhhh, so that the company's product quality is steadily improved.
