Production Process of Aluminum Alloy Door and Window Profiles


  The production process for door and window profiles primarily involves extruding aluminum alloy to create various components used in the fabrication of doors and windows. When discussing the manufacturing process for aluminum alloy door and window profiles, one might wonder whether it is similar to that of other aluminum extrusions. Indeed, it is broadly similar; however, there are still some distinct differences.

  The environmental friendliness, dimensional stability, ease of processing, and aesthetic appeal of aluminum alloy profiles are all readily apparent, which is why they are widely used in window and door profiles. During manufacturing, these profiles undergo melting and casting, extrusion, heat treatment, and surface finishing to produce the final window and door components that consumers see.

  To ensure a smooth ingot surface, multi-die casting is employed using either magnetic casting or hot-top casting. This approach helps increase extrusion speed, extend the service life of the extrusion die, and improve the surface quality of the extruded profiles.

  The extrusion molding of aluminum alloy door and window profiles is carried out on an automated production line that comprises ingot heating, extrusion, cooling, tension straightening, and sawing. Flat dies and分流combination dies are commonly used for producing aluminum alloy door and window profiles. The discharge table receives the extruded profiles from the extruder and transfers them to the finishing worktable.

  Aluminum–magnesium–silicon alloy is used for aluminum alloy door and window profiles; this is a heat-treatable aluminum alloy. By employing various quenching and aging regimes, the profiles can achieve the desired mechanical properties.

  Surface treatment of aluminum alloy door and window profiles typically involves anodizing, which enhances the aesthetic appeal of the profile’s exterior while also extending its service life.
