Jinlei, a specialized manufacturer of wind turbine main shafts, currently holds over 30% of the global market share for wind power main shafts, making it the world’s largest and most technically advanced R&D and manufacturing enterprise in this segment. In line with its strategic objective of business diversification, Jinlei has been actively expanding into non-wind power sectors. In 2021, the company deepened its cooperation with GE, becoming a qualified supplier of precision-machined hydropower forging products, marking a significant step in the development of its hydropower component business.
Overcoming challenges and racing against time, Jinlei successfully completed the full-process precision machining development within just three months. On May 10, 2021, Jinlei delivered its first fully precision-machined hydropower component to GE. This product was urgently required by the client and, after receiving a request for early delivery, Jinlei was left with an extremely tight timeline. Additionally, as the machining of generator shafts had just begun, Jinlei had to race against time while maintaining full-capacity production. Complicating matters, this was Jinlei’s first foray into deep machining of hydropower products, a process requiring significantly higher precision than wind power components and with no existing hydropower machining experience to reference, the team had to rely entirely on their own innovation and hands-on problem-solving.
Faced with these challenges, the Jinlei team demonstrated resilience and determination:
1.An emergency project team was immediately established, bringing together key personnel from critical departments to jointly tackle technical and operational difficulties.
2.The technical team optimized processes and adjusted machining routes, arranging a series of tests and experiments to refine the production workflow
3. Production workshops reorganized their schedules, ensuring seamless integration of the sample products into the production line without disrupting the normal production of other products.
4. The quality control team maintained continuous on-site inspections, minimizing idle time and preventing unnecessary production halts.
With the strong support of GE’s technical experts, Jinlei successfully completed the inspection of two generator shafts over the Labour Day holiday period. Notably, the team achieved a breakthrough by conducting simulated on-site assembly tests under real operating conditions, effectively eliminating risks associated with on-site installation. The rapid and successful delivery, coupled with flawless assembly performance, earned high praise from the client, who also fully affirmed Jinlei’s precision machining capabilities.
This first set of products embodies the wisdom and effort of Jinlei’s team and once again created a remarkable achievement for the company. The completion of this full-process project not only shortened delivery lead times for the client, reduced project risks, and optimized the client’s supply chain management, but also demonstrated Jinlei’s growing strength in non-wind power sectors.
Looking ahead, Jinlei will continue to enhance its research into hydropower products, further invest in supporting precision machining equipment, and strengthen its capacity to meet a broader range of client product needs.
