Railroad Elastic Clip

The Railroad Elastic Clip is a critical component in modern railway infrastructure. Designed to secure rails to sleepers (ties), the rail clip provides strong elasticity, vibration damping, and reliable holding force, ensuring track stability, safety, and long service life. It is widely used in high-speed rail, heavy-haul freight lines, urban transit, and industrial tracks.
Railroad Elastic Clips are engineered to withstand dynamic wheel loads, temperature variations, and environmental stress, delivering consistent performance in demanding railway environments.

 Raw materials

Long-term high-quality spring steel from reliable and certified manufacturers.

 

 Cut

Spring bars must be cut to the required length.

 

 Heating

Forging temperature (950-1000 degrees Celsius), but overheating should be avoided to check for decarburization.

 

 Forming

Appropriate heating rods should be transferred to the forging press.

 

 Hardening

The forged rail clamps are moved to the quench tank. Check the dimensional accuracy and quench hardness of the rail clamps before tempering.

 

 Tempered

The rail clamps are tempered at approximately 350 degrees Celsius to achieve proper toughness in the spring.

 

 An examination

Products are thoroughly inspected according to the specifications and designs of China CRCC and customer requirements.

 

 Package

Railroad Elastic Clips can be packaged in woven bags or according to customer requirements.
