With the development of the national economy and the progress of the machinery industry, China's coupling industry has achieved gratifying results and become a well-known coupling industry powerhouse. However, size does not necessarily mean strength. China's flexible coupling industry also has many problems, such as low overall casting quality, lack of a highly concentrated industrial cluster, and serious overcapacity in casting production. These are bottlenecks that limit the development of China's coupling industry, and will enable it to enter a healthy development path in the future. Below, Shanghai Maidong, a tire coupling company, will introduce in detail the challenges and opportunities faced by new forms of couplings.

Energy conservation, emission reduction, and low-carbon economy have become long-term trends, while driving a group of rapidly developing new industries. The combined force of internal and external factors is driving China towards a low-carbon economy. Industries such as high-speed trains and rail transit have also put forward new requirements for the coupling industry. All aspects of the development of the coupling industry are necessary to promote the rapid and effective transition of the flexible coupling industry towards the "low-carbon economy era". The coupling industry, as the foundation of manufacturing, is known as the "mother of industry". The direction of the coupling manufacturing industry and its entire industrial chain affects every "nerve" of the manufacturing industry. In response to this request, the coupling industry first adopted lightweight materials to replace heavier materials, such as developing magnesium and aluminum alloys, replacing steel and metal with plastics, and developing high-strength and high stiffness materials.

The direction of the development of the coupling industry can be seen that paying attention to the low-carbon issues of the elastic coupling manufacturing industry and its entire industry chain, in addition to raw materials, consumer equipment, and waste gas disposal, should also achieve the maximum scope and level of consumer intelligence in the coupling manufacturing industry. At the same time, we actively purchase advanced low-energy and environmentally friendly processing equipment, as well as waste gas and waste disposal equipment, to achieve the goal of green consumption. The wave of global decarbonization is rapidly approaching, and low-carbon economy has become a hot topic, which should be said to be an expected thing. Due to its low-carbon economy and advanced technology, the intelligent industry is in line with the current overall economic development direction. Currently, a series of policies have encouraged coupling enterprises at home and abroad to engage in green consumption, with the aim of "energy conservation, emission reduction, and material conservation".

Domestic coupling enterprises can actively try to cooperate with foreign coupling industries or stop related technical exchanges to improve their own technology and management. Closing the door will inevitably lead to falling behind and failure. Whether it is related domestically or within the same enterprise, or between domestic and foreign enterprises, they should learn from each other and create their own ideas in order to carry out the project. Although couplings are accessories in nuclear power plant equipment, they are crucial. So far, some high-tech couplings such as main steam isolation valves, large-diameter safety valves, and seismic control valves have not been seriously broken.
