fast clip / Rail fast clip / Elastic clip for rail fastening system

 

The E shape rail elastic clips are used with concrete sleeper to fasten rails on both sides. The rail clips are usually made of forged spring steel, which are manufactured by hot forging process. The forged rail clipsare considered to be better than other metal forming process due to most uniform microstructure.

 

Backed by a modernized manufacturing facility and a diligent workforce, Zhongyue  manufacture, supply and export Elastic Rail Clip. These products find usage in the railwaymen for securing the tracks on the ground. With high elasticity, these products can be molded in varied dimensions. Our clients appreciate these products for their high strength and longer service life with non-corrosive surface. Elastic Rail Clip is packed in special packaging material so that it does not get damaged at the time of dispatch.

 

In our large product line, we also provide Elastic Rail Clip at affordable rate of price. These clips are produced using the best raw material available in the market. These are also properly molded and designed as per the set industrial standard.

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.

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.
