Rail clip is a component of railway fastening systems. It is used to fix the railroad track to the underlying baseplate and sleepers. The clamping force by rail clips helps to maintain the gauge and prevent the rail from moving in the vertical and horizontal direction relative to the sleeper. One extensively used type of rail clip is an elastic rail clip made of hot-pressed spring steel. Its energy produced at elastic deformation can alleviate the vibration and shock when trains move.

Raw material refers to a long spring steel rod. The first step is to shear the raw materials into the required length. Then put the sheared spring steel into the heating furnace. The temperature in the furnace is 950-1000℃. After heating, the clips are formed through three stages of bending by hot molding equipment. After forming, the elastic rail clips are conveyed to a quenching oil tank. After quenching, the elastic rail clips are tempered at 400-500°C. The elastic rail clips are finally oiled and packed. The elastic rail clips must have a hardness between 40 and 48 HRC.
From the first step of raw material purchasing to the final step of finished products, we do strict inspections. Gnee Rail uses high precision inspection machines to make sure the finished elastic rail clips meet the requirements.
