The temperature control, speed of extrusion, and the design of the die are critical factors that determine the success of the process and the quality of the final product.
  • In many cases, when the aluminium profile of doors and windows is deformed and repeatedly pressed, it is found that the maximum wind pressure is seriously inconsistent with the design requirements. The reason is that the wall thickness is not fully considered when selecting the aluminium profiles for door and window. In general, the determination of the wall thickness is combined with the characteristics of the section of the profile, and there is no uniform standard. In general, thin-walled aluminium profiles are not accepted in window and door fabrication. The force-receiving members of the aluminum doors and windows include the frame, the upper glide path, the window fan material, etc. The actual measured dimensions of the minimum wall thickness of these stressed members shall be not less than 1.4 mm for the outer window and not less than 2.0 mm for the outer door. The detection method uses a vernier caliper to perform on-site random sampling inspection of the aluminium profile.
