Problems solved by technology

[0002] Aluminum profiles are widely used in aluminum doors and windows, suspended ceilings and other construction fields. In order to ensure that doors and windows have a certain strength without deformation, and to ensure their appearance is beautiful and free of defects, in addition to improving the structure of aluminum profiles, various manufacturers have There are many factors affecting the surface quality of aluminum profiles, such as the quality requirements of ingots, the design of molds, and the precision requirements of processing will affect the surface quality of aluminum profiles, and the extrusion process of aluminum profiles is A very important factor affecting its strength and performance, the surface quality defects of general aluminum alloy profiles include slag inclusions, extrusion streaks, scratches, rough surfaces and other molding defects, although this is inevitable to a certain extent, but through The method of improving the process improves these defects, otherwise it will definitely affect the quality, appearance and use of the profile, and the quality of the product cannot be further improved
