E shape rail clamps railroad elastic clips for railway fastening system
Elastic rail clip is one of the common railway fasteners in the railway system. In general, elastic rail clip is made of forged spring steel and has many applications. No matter as a part of rail fastening system or as a rail fastener, elastic rail clip is used with other railway track parts, such as railroad spike, rail pad, tie plate and plastic dowel.
Elastic rail clip function
Like other rail fasteners, the main function of rail clip is fastening railway sleeper and steel rail together. The rail clip is considered as one of the best ways to ensure that rails do not move, bend, warp, or rot. There are data shows that each elastic rail clip can bear about two tons of force upon a railway track.
Rail clip types
For different applications and national standards, elastic rail clips can be classified into various types,
including rail e- clip, SKL rail clips, Nabla rail clip, Deenik clip, crane rail clip, Russia rail clip as well as other standard rail clips.

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:
- 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.
Inspection during the production process
How is the quality control of ZhongYue rail clips?
We own a full set of strict quality control system to produce rail clips, from raw material purchasing till the finished clip application. There’s a professional inspection team to check about each process of the production line and every two hour out of the line.
