AI Technical Summary

Problems solved by technology

[0003] People widely use aluminum profiles to make windows, doors and various partitions. Aluminum profiles are also popular among users because they are lighter, more beautiful, and fire-resistant than steel and wood. The existing aluminum profiles for doors and windows have complicated structures. The installation personnel have high technical requirements. Not only is the installation cumbersome, but also time-consuming and labor-intensive. There are also defects such as poor sealing between aluminum alloy objects, especially some unreasonably designed profiles, loud noise when moving, and easy deformation of components.
