How to control the quality of rail clip?

How to control the quality of rail clip?

Over 43 years experience in manufacturing rail clip&Rail Tension Clamp since 1976,Safety is very important to very passenger,and quality is our first principle.

Firstly,For Raw material checking. Regular confirmation of materials: arbitrary furnace Numbers are selected by the quality inspection department of the company and sent to the third party for testing. The third party test results are compared with the company's internal test results for confirmation every year

Chemical composition analysis of material 60Si2Mn


  • Si  1.50-2.00   S<=0.020
  • 60Si2Cr   S<=0.020

Secondly,Tempering microstructure requirements: uniform tempering troostite and sorbite, the heart allows a small amount of intermittent iron elements

Thirdly,The process of producing:Control of the cutting material size of rail clip-Heating(The temperature is controlled by temperature control meter in the process range)-Mould in good condition-Quenching-Inspecting(hardness/metallography/Clamping force/The fatigue test etc)



       The Last,Packing.we use standard export carton for the rail clip and confirm all the rail clip arrived in perfect.
