Riyue Heavy Industries Co., Ltd. specializes in the research, development, production, and sales of metal materials. Renowned for its large-section ductile iron castings, the company is a leader in its field. This issue of Haitian Precision takes you to Riyue’s Gansu base to explore the story of this company and its people.

Stepping onto the vast Gobi Desert, the distant Qilian Mountains encircle the expansive land, while large trucks transport goods along endless highways. Continuous rows of wind turbines operate year-round, delivering clean energy to the central and eastern regions of China. This area, Jiuquan, is one of China’s richest in wind energy resources and has excellent development conditions.

Riyue Heavy Industries (Gansu) Co., Ltd. is located in the Jiuquan Economic and Technological Development Zone. Leveraging the rapid growth of the new energy industry and the rich geographical resources of Jiuquan, Riyue Heavy Industries established its first base outside Ningbo here. Within just eight months of construction, a 120,000 square meter factory emerged, showcasing the impressive “Riyue Speed”.

Riyue Heavy Industries started in 1984, initially producing small conventional products. As its business expanded, it began collaborating with Haitian. Whether producing injection molding machine templates or large casting components, Riyue and Haitian grew together, co-developing and manufacturing complex parts.

In 2014, Riyue expanded into machining, urgently needing a batch of machine tools. Haitian Precision became the first choice, promptly providing the necessary equipment. Ke Hongguo, Deputy Plant Manager of Gansu Riyue, recalls, “We have great confidence in Haitian. Our Xiangshan base has had good experiences using Haitian’s machine tools, so we prioritized Haitian Precision’s machining centers for our Gansu base.”

Gansu Riyue primarily manufactures components for onshore wind turbines, including hubs and bases, requiring machine tools with high rigidity, strong cutting power, and a wide processing range. The factory’s eight large heavy-duty gantry machining centers from Haitian Precision, with ultra-wide ram slides and six-meter-wide gantries, ensure stable operations. Deputy Plant Manager Cai Anqiang praises, “Haitian Precision’s gantry machines have wider ram slides than usual, reaching 500×500 mm, meeting our cutting rigidity requirements.”

Cai has experienced the stability of these machines firsthand. The first 10-meter gantry at the Xiangshan base, installed ten years ago, still runs smoothly with a very low failure rate. “Haitian Precision equipment has a much lower failure rate than others, staying below 2%, which is a very good figure, giving us peace of mind in production.”

In 2022, during the harsh winter of December, with heavy snow in the northwest, Haitian Precision took on the significant responsibility of ensuring timely installation of equipment at the Gansu Riyue site. They sent a highly skilled service team to live and work alongside Riyue employees, even staying in containers to provide around-the-clock service. This dedication helped bring the first phase of the 100,000-ton annual wind power casting and machining project to life.

 

Cai reflects, “During the pandemic, with limited equipment and manpower, Haitian Precision’s team arrived promptly, helping us meet our delivery deadline by the end of 2023. Their service was exceptional.” Comprehensive service is the final line of defense for safeguarding production, and Haitian Precision’s commitment to customer needs, driven by a mission of ensuring success, supports every production requirement.

Leaving Gansu Riyue, we witness the stunning scenery of the desert, with the setting sun casting a golden glow on the slowly turning wind turbines. As China’s dual carbon goals continue to be implemented and advanced, the pioneers on the Gobi Desert truly become leaders, filling the gaps in Jiuquan’s new energy equipment manufacturing industry.

The future is bright, and the journey has just begun. The new energy industry is crucial for high-quality development of new productivity, and Haitian Precision and Riyue Heavy Industries will collaborate to form a complementary and synergistic development system within the industry, continually driving the advancement of China’s green industry.
