Jinhui Company has a history of over 20 years in producing railway rail transit products, mainly distributed in North America, European markets, and CRRC's heavy-duty freight trains and high-speed trains.
The products mainly include buffers, spring heads, hook tail frames, hook tongues, brake discs, eye rings, connectors, axle box bodies, support seats, hook head covers, etc., which are compatible with various domestic and foreign locomotives
Connection and buffering system of locomotive carriages: buffer, spring head, connector, hook yoke, hook tongue
Locomotive braking system: brake discs
Locomotive traction system: eye loop, support seat, hook cover
Locomotive steering system: axle box body
Once the traction, connection, braking and buffering systems, as well as steering systems of high-speed passenger cars and heavy-duty trucks fail, they can cause serious safety accidents such as vehicle damage and fatalities. Therefore, we prioritize the quality of the rail transit components we produce. Through comprehensive process design and solidification simulation verification, we ensure the reliability of the product process, ensure product quality, and have good mechanical properties. Through radiation and magnetic powder testing, Ultrasonic and other non-destructive testing, static, fatigue impact and other destructive testing methods are used to verify the quality of castings and provide safety assurance for products.
Another characteristic of locomotive assembly parts, especially the components of the buffer system and connection system, is that the assembly position of the castings is difficult to process in the later stage, and there is a high requirement for dimensional accuracy of the castings. Jinhui products have high dimensional accuracy, good dimensional consistency, and interchangeability to meet customers' requirements for quick product replacement.
Jinhui has multiple production processes coexisting, suitable for the production of products with different structures, sizes, and batches; The independently developed molding materials and core assembly molding process of Jinhui effectively reduce the probability of casting cracks and provide product safety.
To increase customer trust and enhance product competitiveness, we have passed the American Railroad Association AAR qualification certification, and our products have been recognized in the international market. The main materials are AAR M201 Grade C, E, E+, etc.
