Himile is mainly engaged in the development, manufacturing, and distribution of tire molds, giant tire curing presses, building drums, and castings. The company also produces about 30 percent of the world's automobile valve cores.

In recent years, Himil has made major achievements in developing subsea oil production equipment and related processing equipment through technological innovation.

Previously, only a handful of European and US multinationals could manufacture deep-sea risers, which were expensive and often limited in China. In order to change this, Himile began to put together a research and development team in 2015. After thousands of tests, they finally succeeded, said Tang Lixing, a senior manager from Himile.

The deep-sea drilling riser has enhanced the company's influence in the deep-water equipment industry and also laid a foundation for the company's development of other deep-sea products in the future.
