Most of the industrial aluminum profiles are developed according to the existing needs of users. Some industries have strong development capabilities, such as rail vehicle manufacturing, automobile manufacturing, etc., but some small industries lack their own development capabilities or are not aware of the available industrial aluminum profiles. To replace current materials, it is necessary for manufacturers to assist users in developing alternative industrial aluminum profiles. To do this, it is necessary to go out and conduct detailed investigations on the materials used in all walks of life to find out which aluminum profiles are suitable for replacement. Through these developments, the market for industrial aluminum profiles can be expanded, especially the development of large-scale industries, and the increase in market demand can reduce the fierce competition faced by the large and extra-large extrusion lines under construction after the completion. Improve the overall production technology of industrial aluminum profiles. Most of the industrial aluminum profiles have strict requirements on material, performance, dimensional tolerances, etc. Although the profit of industrial aluminum profiles is higher than that of architectural aluminum profiles, its production is relatively difficult, and the technical requirements are also higher, especially complex The production technology of large, flat, wide and thin-walled industrial aluminum profiles still lags far behind foreign countries.
