How do we produce rail clips?

GNEE RAILWAY RAILWAY produces the rail clips according the scientific procedures of rail clip production strictly and the specific procedures are as follow:

Raw material: Premium grade spring steel sourced from a reliable and certified long term producer.

• Shearing: The spring steel bar has to be sheared as per length required.

• Heating: to forging temperature (950-1000 degrees Celsius), but over heating shall be avoided to check decarburization.

• Forming: Proper heated bar is transferred to power press for forging.

• Hardening: The forged rail clips are transferred to quenching tank.

Dimensional accuracy and quench hardness of rail clips are checked before tempering.

• Tempering: The rail clips are tempered at about 350 Celsius to achieve appropriate toughness in the spring.

• Inspection: The products are then checked thoroughly as per China CRCC and customer required specification and design.

• Packing: Clips can be packed in woven bags or upon customer requirement.
