Main Defects and Causes of Aluminum Alloy Extrusion Materials Defects usually refer to areas that do not meet the ordering standards or conditions, which either affect the appearance or use of the product. They are avoidable in production and are a direct reflection of product quality. Acceptable defects that only affect the appearance of the product and can be eliminated through subsequent finishing or processing without affecting its use, such as surface contamination, scratches and scratches that are not out of tolerance, pits, bending, twisting, flat gaps, peeling, bubbles, extrusion cracks, dimensions, etc. These defects are usually caused during extrusion and subsequent finishing, packaging, and transportation processes. Unacceptable defects that cannot be eliminated through subsequent finishing or processing, such as coarse crystal rings, layering, shrinkage, poor welding, unqualified flaw detection, excessive oxide film, metal and non-metallic slag, heat treatment cracks, over burning or overheating, as well as excessive scratches and scratches, bending, twisting, flat gaps, peeling, extrusion cracks, dimensions, etc. Some of these defects are inherited from metallurgical quality, such as unqualified inspection, excessive oxide film, metal and non-metallic slag, etc., and some are caused by process and mold reasons in extrusion production. Surface pollution, scratches, and bumps - weak quality awareness during production and lack of protection for product surfaces; Or there is an issue with the packaging method, which may cause collision or rubbing during rotation and transportation. Scratches - the mold work area is not cleaned thoroughly; The working track of the press or saw machine is not cleaned thoroughly. Pitted surface - insufficient hardness of the mold working zone; The extrusion temperature is too high; The squeezing speed is too fast. Bending, twisting, flat clearance - mold design issues; Unreasonable extrusion temperature or extrusion speed; The quenching medium temperature is too low; Insufficient stretching or other finishing methods. Peeling and bubbles - loose ingots; The size of the extrusion pad is unreasonable; Oil stains on the surface of the ingot or extrusion cylinder; Squeeze temperature or speed too fast. Squeeze cracks - the extrusion temperature or speed is too fast. Size - Unreasonable mold design; The extrusion speed control is inconsistent before and after. Coarse crystal ring - improper control of alloy composition; Unreasonable extrusion process design; The heat treatment temperature is too high and the insulation time is too long. Layer forming - surface defects on the ingot not cleaned by turning; Oil stains on the surface of the ingot or extrusion cylinder; Unreasonable mold design. Shrinking tail - the squeezing speed is too fast; The temperature difference between the extrusion cylinder and the ingot is large; Less residual extrusion or less removal of the end of the product; There is oil stains on th...

Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. The production process of aluminum profiles mainly includes three processes: casting, extrusion, and coloring (coloring mainly includes oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, etc.). Aluminum materials are extremely unstable in the air and can easily form oxide films that are difficult to recognize with the naked eye. Due to the different processing methods for aluminum parts, such as casting, direct cutting from extruded sheets, mechanical precision processing, or heat treatment or welding after different processes, the surface of the workpiece will present different states and varying degrees of dirt or marks. Therefore, in the pre-treatment process, the pre-treatment process must be selected based on the actual situation of the workpiece surface. In the pre-treatment process, it should be noted that although the natural oxide film on the surface of fine machined parts is only initially formed, there is an excessively thick oxide layer formed during the casting process on the surface that has not been machined, and a layer of oily and sintered coke is formed before the workpiece is transferred to the heat treatment or welding process. The treatment precautions for these situations are as follows: (1) Attention should be paid to the pre-treatment process of precision machined parts: Although the natural oxide film on the surface of the precision machined parts is only initially formed and easy to remove, it is heavy and greasy, especially in and around the eyelets (added due to lubrication needs during machining). These types of workpieces must be cleaned with organic solvents first. If directly washed with alkali, not only is the oil heavy and difficult to remove, but the precision machined surface cannot withstand long-term strong alkali corrosion, The result will also affect the roughness and tolerance fit of the workpiece surface, which may eventually become a waste product. (2) The issues that need to be noted in the pre-treatment process of casting molded parts. Not all surfaces of cast parts have undergone mechanical processing. Unmachined surfaces have an excessively thick oxide layer formed during the casting process, and some even contain sand layers. At this time, the original oxide film in this area should be removed first using machining or sandblasting methods, or processed after alkali washing. Only in this way can the original oxide layer in the unprocessed area be removed and the tolerance dimensions of the machined area be avoided from changing. (3) During the pre-treatment process of workpieces that have undergone heat treatment or welding, attention should be paid to the following issues: according to the process requirements, the workpieces need to be cleaned with organic solvents before being transferred to the heat treatment or welding process to remove s...

Act On The Orders And Take The Initiative In 2022, the domestic epidemic situation is severe, showing a multi-faceted situation. Shenzhen, Jilin, Shanghai, Hong Kong and other places sound the epidemic alarm. Guangya Aluminum is striving to expand its business and promote high-quality development. At the same time, it also pays close attention to various places. The latest development of the epidemic. After learning about the construction needs of the permanent community isolation treatment facility designed and built by the central government in Hong Kong, Guangya Aluminum Co., Ltd. took the initiative to contact the project builder to accurately match the technical standards and requirements of aluminum profiles, and assist in the construction of "Hong Kong Penny's Bay Phases 5 & 6 and its opening." After nearly two months of intense construction, this project was completed and delivered on April 28, 2022, and it was put into use smoothly, providing a solid guarantee for Hong Kong’s response to the epidemic prevention and control. To Attack The Fortress, And The "Epidemic" Is Inescapable Duty The additional isolation facility in Penny's Bay covers an area of more than 450,000 square meters and has a construction area of more than 260,000 square meters. It is the largest community isolation and treatment facility project in Hong Kong. After completion, it will provide more than 6,500 isolation units. The additional isolation facility in Kai Tak covers an area of more than 80,000 square meters, with a construction area of more than 140,000 square meters. After completion, it will provide more than 3,000 isolation units. Both isolation facilities were designed and constructed by China State Construction International. After the project is fully put into use, it is expected to provide about 9,500 isolation units for Hong Kong. This project has a large amount of work, tight delivery time, high standards and great responsibility. In the face of the new crown epidemic in Shenzhen and Dongguan, Guangya Aluminum Co., Ltd. Improve process methods(Anodized 25um thickness) , and strive to ensure the supply of raw materials that meet the local acceptance standards in Hong Kong in the shortest time. In order to further shorten the delivery time, Guangya's production and delivery teams worked hard all night to seize the progress, and went all out to assist the Hong Kong Epidemic Prevention and Isolation Center Project in the supply and transportation of door and window materials, and contributed to the Hong Kong epidemic prevention and control work. Glorious Mission, Live Up To The Heavy Trust Guangya Aluminum actively responded and cooperated throughout the process, made outstanding contributions to the project, was awarded the title of "Excellent Supplier", and received a sincere letter of thanks from partners. At the critical juncture of stabilizing and controlling the epidemic, it is Guangya's honor and responsibility to ...
