AOQUN platform screen door brush has been installed in many countries and cities with the annual growth of 20 railway lines. We have supplied the platform screen door brush in total of 75 railway lines until now. Besides, we have cooperated with CRRC, Fangda, Favillay, Panasonic, Westinghouse, Kone and other famous brand customers. We can say that, where is platform screen door, where is AOQUN door brush.The project leader of Xi’an Metro Line 4 platform screen door found us in June 2017, told us that they were doing the 1 million times friction test for the platform screen door brush from suppliers. Some platform screen door brushes have been running for 750,000 times, unfortunately, these platform screen door brushes have already been replaced twice, which can not pass the 100 million times friction test. For the main reason is brush filament loosing severely.We are not strange with this problem. We had received the feedback of Hangzhou Railway Line 4 and Beijing Railway line with same problem. Because the railway average speed is 36km, the maximum speed is 80km, which is high-speed, so the platform screen door brush should have the 100 million times friction test to achieve the sealing function with high speed friction. Therefore, the platform screen door brush needs to be good flexibility, no filament loss, soundproof, hot and cold insulation without deformation after 100 million times friction test.
AOQUN platform screen door brushes have passed the 100 million times friction time when got the first project of the platform screen door industry. The quality of the AOQUN platform screen door brush still very good after so many years, for our brushes have passed every friction test for every railway line application. Moreover, we are the first one in the industry to publish 《Finished Product Inspection Standards》 to indicate the tensile requirement and operation requirement. We can do standardized, professional and efficient!The platform screen door brush to play the important role as windproof, noise proof, hot and cold insulation for the platform screen door, to achieve the effect of sealing and energy conservation, and to create an ideal ride environment for you.
