Analysis of Future Development Trends of Automotive Door Industry

At present, most of the mainstream car models on the market use the door panel gold structure mainly consisting of “full-size inner and outer panel structure”, “rolling window frame structure” and “semi-open door structure”. The seal structure adopted on the doors of these different structures is also Differently, they have their own characteristics, as well as the structure of the sealing strips used.

Champ Consulting industry analysts pointed out that in the course of many years of development, automotive powers have gradually formed their own technical characteristics and process basis, and the products they design and produce have their own characteristics and differences.

The market concentration of China's auto industry is much lower than that of foreign countries.

The "2014-2018 China Door Industry Forecast and Investment Strategy Research Report" published by Champion Consulting shows that insufficient capital investment, small production scale, and weak strength have prevented China's auto door companies from competing with international multinational parts companies. For a long time, due to the fact that the entire vehicle is in the seller's market, the investment in the automobile industry in China has been focused on the expansion of the vehicle's capabilities. The investment in spare parts has been severely deficient, which has led to the prominent problem of small, scattered, and overly-prone auto parts companies, and the overall competitiveness is extremely weak. Under the strong strength of foreign investment and joint ventures, local car companies are facing an unprecedented impact. Judging from the current development of domestic vehicles, the market prospects of the doors are very good, but now the competition between the various door manufacturers is very fierce, basically divided into joint ventures, wholly-owned two camps.
