Qingdao Qingli Environmental Protection Equipment Co., LTD is one of the leading manufacturers of Rockwool Production Lines. Our quality of manufacturing and stability of machines’ performance are at a worldwide level. The energy efficiency and the protection of the environment are two of the main aspects we strongly consider when manufacturing our Rockwool Production Lines.

We were established in 1958 as a state owned enterprise and a large scale manufacturer of iron melting furnaces for the metallurgy. With the changing energy efficiency requirements for housing and industry insulation in China and worldwide, our board of directors saw the potential in the field and decided to concentrate our efforts in manufacturing rockwool production lines. Soon, we became a fully equipped rockwool machinery manufacturer. Now, we are a privately-owned company and one of the few worldwide factories that can manufacture a full set of machinery for the stone wool industry. Our mission is to help the globe by creating great energy-efficient machines that produce energy-saving insulation for a better world.
