Multi-system coverage of Rail Transit Casting by Ningbo Jinhui Precision Casting Co., Ltd.

The buffer connection system of rail transit vehicles is the key to ensure smooth operation between vehicles. The buffers, spring heads, hook tail frames, hook tongues, connectors and other parts produced by Ningbo Jinhui Precision Casting Co., Ltd. have excellent impact resistance and high strength performance, which can effectively absorb and alleviate the impact and vibration during train operation, reduce the mechanical damage between vehicles during the operation of high-speed trains and heavy-loaded trucks, and improve the safety and stability of operation.

Rail transit vehicles need to withstand huge traction during operation. The traction system parts such as eye rings, brackets, hook head covers produced by Ningbo Jinhui Precision Casting Co., Ltd. are designed for high loads and complex working conditions. These products not only have excellent mechanical strength and durability, but also can maintain stable performance in long-term operation, providing reliable guarantee for the efficient traction of rail transit vehicles.

The braking system of the train is an important link to ensure safe operation, especially under high-speed and heavy-load conditions, which requires extremely high accuracy and stability of the braking force. The brake disc products of Ningbo Jinhui Precision Casting Co., Ltd. are made of high-performance materials and precision manufacturing processes. They have excellent resistance to thermal fatigue and wear. They can provide stable and efficient braking force under extreme temperature and high-speed rotation conditions, and escort the safe operation of trains.

The steering system of rail transit vehicles is a key link to ensure operational stability and passenger comfort. The steering system components such as axle boxes produced by Ningbo Jinhui Precision Casting Co., Ltd. are precisely designed and advanced in manufacturing processes. They can effectively withstand the complex mechanical loads generated when the train turns, and ensure the stability and dynamic stability of the train at high speed and when turning. These products have excellent performance in impact resistance and fatigue resistance, providing important support for the safe operation of rail transit vehicles.

The Rail Transit Casting of Ningbo Jinhui Precision Casting Co., Ltd. fully covers buffer, connection, traction, braking and steering systems. Not only does it perform well in each system individually, but it also further improves the overall performance of the vehicle through synergy. For example, the close cooperation between the connection system and the buffer system not only enhances the impact resistance of the vehicle, but also improves the operating comfort; the optimized design of the traction system and the braking system makes the vehicle more stable and efficient when starting and braking. This multi-system synergy enables Jinhui's products to meet the high requirements of the rail transit industry for comprehensive performance. At the same time, the products are also suitable for a variety of rail transit vehicles at home and abroad, including high-speed trains, heavy-load freight trains and other special vehicles. Its products not only meet the technical standards of CRRC, but also pass the certification of the American Association of Railroads (AAR), meeting the strict requirements of international markets such as North America and Europe. This wide adaptability enables Jinhui to provide comprehensive technical support for rail transit customers in different countries and regions.

The rail transit system has extremely high quality requirements for parts and components. Ningbo Jinhui Precision Casting Co., Ltd. ensures the reliability and safety of each product through strict quality control measures such as solidification simulation verification, non-destructive testing, and destructive testing. For example, advanced methods such as ultrasonic testing and magnetic particle testing are used to eliminate any minor defects that may affect the operation of the system; static load, fatigue, impact and other tests are used to verify the durability and reliability of the product under extreme conditions.
