in 2004,the first mini-type cnc gas pressure machine in china was created by aigre tech. and successfully applied to the construction of qinghai-tibet railway.the high cold and high altitude seamless lines were laid for the first time.
in 2005,the mini-type cnc gas pressure machine was successfully obtained the administrative license decision by the ministry of railways.then it was supported by the innovation funds for sme on the following year.
in 2006, the first mobile flash rail welding machine with complete independent intellectual property rights was developed and past the science evaluation of chengdu railway bureau.
in 2007,the first fixed rail flash butt welding machine with complete independent intellectual property rights was developed,which filled the gap in this field in china and past the science evaluation of chengdu railway bureau in 2009.
in 2008,the "application technology and equipment development of rail mobile flash butt welding" project was funded by the ministry of railways.
in 2009,the "un5-150z container flash rail welding machine" was successfully obtained the "chengdu key component product certification " and was listed in the purchasing list of important equipment by the ministry of railways.
in 2010, the fixed rail flash welder and the mobile rail flash welder in china was created by aigre tech. and past the administrative license decision by the ministry of railways of china.it has established the dominant position for aigre tech. in the field of rail welding machine design and manufacturing in china.
in 2011, "the new field rail flash welder" project was funded by " innovation driven development fund by sichuan finance".in the same year,more than 20 acres production base was put into operation. aigre tech. strengthened internal reforms and expanded the sales range whose products field extended to the rail welding equipment, welding rail production line equipment, the development of remote control system, rail flash welding rail-road truck, etc.
in 2012, the "un5-150zc slot rail welding machine" on the market which not only meets the groove rail welding, but also meets the national standard rail welding.
in 2013, the "un5-150zb mobile flash rail welding machine" project was supported by the "chengdu key new product project fund ". in the same year,the "un5-150zb1 flash rail welding machine"of high clamping force and high forging force on the market which is suitable for for high-speed rail welding.
in 2014,obtained the certification of "national high-tech enterprises".
in 2015, the efficient and economic plan for "high-speed rail welded rail line and design scheme" to quickly establish a temporary rail welding base, and to solves the problem of large investment and high operation and maintenance cost.
in 2016,obtained the "ce certification" and opened up the export channel to european and american countries.
in 2017,intensified its research and development, and a new type of rail flash welding rail-road truck, extremely low harmful particles and gas emissions of rail flash welding machines have been put on the market. at the same time through the new technology research and development, it meets the requirements of india, european standards and other foreign standards for rail welding.
