In November 2016, the bauma China, one of the most popular exhibitions in the machinery industry, was grandly opened in Shanghai, China. In this exhibition, we showed our company's manual, semi-automatic and automatic machines to the exhibition audience.

What we highlight this time is the double proportional valve hydraulic system in large machines. The computer can automatically adjust the pressure and oil flow at the same time, which can well solve the problem of insufficient stability in the process of machine operation，highlight the technical performance of our block-making machine.We also communicated with many counterparts and visitors from different countries in the exhibition.

Qingdao HF Machinery has been established for more than 30 years.
