Gnee Steel (Tianjin) Co., Ltd. is one of the most reliable manufacturers and suppliers of fastening systems-rail clips in China, also supports customized service with low price. Please feel free to buy cheap fastening systems-rail clips made in China here from our factory.
Rail elastic clip is used to fasten the rails to the underlying base plate together with the concrete sleeper. Usually rail clips are made of forged spring steel which is produced by hot forging process. Because of the uniform microstructure of forged clips, it is considered to be better than other metal forming process.

Features
A. Shoulders insusceptible to accidental damage
B. Robust toe insulators
C. Less and simple hand tools required for installation
D. Easy to use in the concrete sleeper factory
One of the key features of the fast clip system is the new plastic seal plate, which is used to seal the hole in the sleeper mold and is then cast into the sleeper. This design minimizes the contact between the steel mold and the cast iron shoulder of the assembly, increasing mold life accordingly. It also prevents slurry from leaking into the shoulder.
Rail clip processing procedures includes:
1. Raw material purchasing
2. Shearing
3. Heating to forging temperature
4. Forming
5. Hardening
6. Tempering
7. Surface treatment
8. Inspection-Packing
To produce rail clips usually use spring steel bar as the raw materials, before heating, raw materials must be sheared according to the length required. Then they are heated to 950℃ to 1000℃, next works transfer the heated bar to power press for forging, in accordance with drawing three sets of dies and fixtures are kept before hammering. The following procedure is to convey the forged rail clips to quenching tank. Then check the dimensional accuracy and quench hardness of the rail clips. The next procedure is tempering to achieve appropriate toughness in the spring. And the final step is to pack the rail clips after serious inspection.
