During the "Twelfth Five-Year Plan" period, the domestic automobile industry will grow at a super high speed and enter a stage of stable, healthy and rapid development. And auto parts will enter the peak period of rapid development following the rapid development of complete vehicles. The increase in car ownership, the increase in vehicle production, and the shift of global procurement to China have all brought opportunities for the development of the domestic filter industry.
China has become an important filter production base in the world, and the global filter industry is gradually shifting to China.
At present, there are more than 1,000 domestic filter manufacturers. Due to the diversity of vehicle filter products and structures, it is not only suitable for mass production with a high degree of automation, but also can be used in small batch workshops with manual operations. Therefore, most of the production enterprises are small in scale, with more than 30 large and medium-sized enterprises, and no monopolistic super-large enterprises have been formed in the industry.
