A giant factory in Qingdao turns out three fleets of high-speed trains every four days. CRRC Qingdao Sifang designs and manufactures nearly half of China's high-speed trains. The company has been using Atlas Copco nutrunners and wrenches for years, and it has recently purchased another 60 Power Focus controllers and 180 virtual stations. The advanced tools have greatly enhanced assembly quality, reduced the chances of human error and improved the factory's ergonomics.
