Rail Clip Production Process

How do we produce rail clips?

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

  1. Raw material: Premium grade spring steel sourced from a reliable and certified long term producer.
  2. Shearing: The spring steel bar has to be sheared as per length required.
  3. Heating: to forging temperature (950-1000 degrees Celsius), but over heating shall be avoided to check decarburization.
  4. Forming: Proper heated bar is transferred to power press for forging.
  5. Hardening: The forged rail clips are transferred to quenching tank. Dimensional accuracy and quench hardness of rail clips are checked before tempering.
  6. Tempering: The rail clips are tempered at about 350 Celsius to achieve appropriate toughness in the spring.
  7. Inspection: The products are then checked thoroughly as per China CRCC and customer required specification and design.
  8. Packing: Clips can be packed in woven bags or upon customer requirement.
