Six-axis machines for inline parts cleaning
100 percent humidity and a pH of 9: in such conditions, the deployment of robots poses real challenges. These are the very parameters under which Stäubli robots are delivering reliable service on the parts cleaning line at the Nissan Dongfeng engine plant in China.
