The industry of drilling brake linings in China has gradually upgraded alongside the deep advancement of oil, gas, and mineral resource exploration and development. In the 1980s and 1990s, the large-scale development of onshore shallow well drilling operations drove brake linings into the stage of mass production. At that time, products mostly used cast iron or semi-metallic materials to meet the basic braking needs of conventional drilling equipment. Since the turn of the century, the rapid development of deep wells, ultra-deep wells, and offshore drilling platforms has imposed stringent requirements on brake linings, including high-temperature resistance, heavy-load impact resistance, and resistance to mud and seawater corrosion. This has driven the material iteration towards resin-based composite friction materials and ceramic-reinforced wear-resistant materials, with structural optimization for integrated designs incorporating heat dissipation channels. In recent years, the emergence of high-end demands such as shale gas development and polar exploration, coupled with the improvement of standards, has accelerated the industry's phase-out of low-performance production capacity, focusing on safety margins and long-life design. Currently, China has become a major global supplier of drilling brake linings, with products covering all types of drilling equipment, including onshore oil rigs, offshore drilling platforms, and mining exploration drills.

We have established a specialized testing team for drilling equipment brakes, offering customized testing services for friction performance and more, based on drilling depth, medium environment (mud, seawater, dust), and load level, helping products strengthen the safety defense line for drilling operations.
