The 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 clips are considered to be better than other metal forming process due to most uniform microstructure.
Rail clips processing procedures are as follow: Shearing-- Heating to forging temperature -- Forming-- Hardening—Tempering — Inspection — Packing.
The raw materials for rail clips production, e.g. the spring steel bar, has to be sheared as per length required. The sheared rods are heated to the 950 ℃ to 1000 ℃， and then the heated bar is transferred to power press for forging. Three sets of dies and fixtures are kept as per drawing before hammering. The forged rail clips are conveyed to quenching tank. After dimensional accuracy and quench hardness of the rail clips are checked, they will be sent to the next procedure for tempering to achieve appropriate toughness in the spring. The final product will be packed after serious inspection.
For years, the rail e clips have been widely used for the fastening of the rails. They are good choice for transit and heavy–haul tracks for the features of efficient installation, low maintenance costs, excellent fatigue performance over time, and long working range, etc.
Enriched with rich railway industrial experience, AGICO can offer its clients an extensive range of heavy duty rail fastening clips, made up of premium quality and seamless performance, to be used to fasten rails to underlying tie plates. The rail clips produced by AGICO are made up of premium grade spring steel sourced from a reliable and certified long term producer. After over 20 years’ experience on producing rail elastic clips, AGICO has become the largest and most competitive production base of rail clips in China, qualified to tender nationally large and medium scaled rail projects under the China Ministry of Railways, both at home and abroad.
At each single step of manufacturing the clips are stringently tested and completely authenticated. To save time during installation in track, we can provide a special service by pre assembling a SKL clip with a T-bolt and a washer for the customer at our production base before delivery. Besides, corrosion protection layer of the clip surface can be applied.

How do we produce rail clips?
Agico produces the rail clips according the scientific procedures of rail clip production strictly and the specific procedures are as follow:
How is the quality control of Agico 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.
Inspection machine for finished rail clips
At our production base for rail clips, pollution control and energy conservation is a key issue during the designing and construction of the factory to reduce noise of hammer and oil fired furnace as well as reduce smoke release. Preheating the inlet air used in baring of Diesel can save considerable energy as well.
