How High Quality Railway Parts Support China’s Fuxing High-Speed Train

On China’s renowned Fuxing High-Speed Train, the technology of Luoyang Fonyo Heavy Industries Co., Ltd., a leading railway parts manufacturer, plays an essential role. we produces high-quality railway castings and critical components such as stator press rings, gearbox housing, railway wheels, axle hung bearing suspension, and standard EMU motor clamping rings. These products are widely applied in trains running at speeds up to 350 km/h, making our company a key contributor to China’s high-end equipment manufacturing.

1. Stator Press Rings – The Stabilizers of High-Speed Train Motors

A stator press ring is a core component in an electric traction motor, designed to secure the stator windings and resist strong electromagnetic forces and vibrations. For high-speed trains like the Fuxing EMU, the reliability and longevity of the motor is very important, this component directly impact train safety and performance.

Our railway castings for stator press rings feature superior mechanical properties and precise structural design. They reduce end losses, control winding temperature rise, and prevent core lamination deformation, ensuring stable motor performance even under long-term high-frequency operation.

2. Technical Breakthroughs and Patents of Railway Parts

Our stator press rings and permanent magnet motor press rings are mainly supplied to CRRC, with annual production exceeding 500 sets and over 30% domestic market share, generating millions in annual revenue.

Developing these components required a dedicated R&D team of 52 engineers working over two years. The casting process alone was adjusted and optimized 18 times. Following initial deliveries, customer feedback led to dozens of refinements, sometimes requiring overnight testing to overcome technical challenges.

These efforts resulted in significant intellectual property achievements, and these innovations not only filled domestic technological gaps but also strengthened Fonyo’s position in high-end railway castings manufacturing.

3. from Traditional Foundry to Intelligent Manufacturing for Railway Parts

Established in 1998, Fonyo has evolved from single steel casting enterprise to a comprehensive intelligent manufacturing company covering iron casting, assembly, and welding. The company’s annual casting capacity reaches 30,000 tons.

Fonyo products serve high-speed trains, urban rail, subways, and extend to industries such as mining, power, wind energy, and construction machinery. They are exported to countries including Russia, the United States, Germany, and Japan.

Company leadership emphasizes, “We adhere to the philosophy of ‘Creating the Future with Care,’ continuously innovating products and technology in collaboration with platforms like CRRC and China Railway Construction.”

4. Innovation-Driven Growth and Industry Recognition

Luoyang Fonyo Heavy Industries Co., Ltd. specializes in railway gearbox assemblies, railway wheels, and other railway castings, further extending its industrial chain. Multiple patents and industry awards demonstrate the company’s strong technical capability in high-end railway manufacturing.

5. Looking Ahead – Green, Intelligent, and High-End Railway Parts Manufacturing

Looking to the future, we aims to track global cutting-edge technologies and advance R&D for stator press rings and other critical components using new materials, processes, and technology. The company’s vision is to become a globally competitive railway parts manufacturer, building green, intelligent, and high-end equipment manufacturing capabilities while supporting the high-quality industrial development all around the world.
