What are the standards for industrial aluminum profiles on assembly lines?

　　Aluminum profiles refer to cross-sectional profiles with different alloy composition ratios. The alloy composition, processing technology, and production difficulty of aluminum profiles determine their use and price. Common types of aluminum profiles include door and window aluminum, curtain wall aluminum, building aluminum, assembly line aluminum profiles, rail transit aluminum, aerospace aluminum, etc. The production standards for each different type of profile are different. Here, Shandong Pengcheng Aluminum Industry Co., Ltd. comes to talk to you about the standards for industrial aluminum profiles on assembly lines.

　　The assembly line industrial aluminum profile is a cross-sectional profile formed by hot melt extrusion of aluminum rods, commonly used in the automation machinery industry, automated conveyor production line industry, and so on. And its aluminum alloy grade is generally 6063-t5, with a hardness between 8-12HW. Its standards mainly include the following:

　　1. National standard GB-6892-2008

　　This standard has been implemented since 2008 and is based on GB/T 8013-2007, JLS H8602-1992, and AAMA 612-02. The standard is divided into three levels: ordinary level, high-precision level, and ultra-high-precision level. The scope includes dimensional tolerance, torsion, bending, flatness, and other contents. Different content scopes have different standards.

　　2. Surface inspection standards

　　The surface standard for industrial aluminum profiles on assembly lines generally requires that the profile surface be smooth and free of burrs, scratches, spots, and color differences. Common surface inspection standards include the following:

　　(1) The diameter of sand holes or bubbles on the surface of the profile should be less than 0.3mm, the depth should be less than 0.1mm, and no more than 4 sand holes or bubbles are allowed between 25 square centimeters.

　　(2) If there are more than 4 units in 25 square centimeters, it is considered unqualified.

　　(3) The scratches on the surface of the profile are less than or equal to 40mm, with a depth of less than 0.1mm and a width of less than 0.1mm. No more than 3 scratches per meter.

　　(4) All types of defects shall not exceed 5% of the surface defects of the profile

　　(5) And the surface of industrial aluminum profiles on the assembly line is strictly prohibited from cracking, non-metallic pressing into objects, deformation, and other situations. Because any point will affect the overall surface aesthetics and the physical properties of the profile.
