Increasing demands for productivity and quality in combination with rising wages and a lack of well-trained specialists present new challenges for China’s industrial companies. That is why the Zhengzhou Coal Mining Machinery Group Ltd. has commissioned 25 automated welding systems from Carl Cloos Schweisstechnik GmbH in the last 5 years. By investing in the modern robot welding systems, Zhengzhou Coal Mining was able to speed up the production processes overall by more than 50 percent and at the same time achieve exactly reproducible results.
