custom industrial extruded aluminum profile

Extruded Aluminum Profile is a type of aluminum product that is formed by forcing heated aluminum through a H13 Extrusion Mould die to create a specific shape or profile. It is commonly used in various industries such as construction, automotive, aerospace, and electronics due to its lightweight, high strength, and excellent corrosion resistance.The material used for extruded aluminum profile is typically 6000 series aluminum alloy, which is composed of magnesium and silicon. This aluminum alloy has good mechanical properties, excellent surface finish, and is easy to extrude.The extrusion process involves heating the aluminum billet to a specific temperature and then pushing it through a die using a hydraulic press. The H13 Extrusion Mould die is designed to create the desired shape of the profile, and the aluminum is cooled as it exits the die to maintain its shape. After extrusion, the aluminum profile can be cut to the desired length and further processed by precision CNC machining or other secondary operations.The production process of extruded aluminum profile includes billet preparation, extrusion, cooling, stretching, cutting, surface treatment, and packaging. The exact process may vary depending on the specific requirements of the profile.Precision CNC machining is often used to further refine the extruded aluminum profile to achieve precise dimensions and tolerances. The tolerance for CNC machined extruded aluminum profiles typically ranges from +/- 0.1mm to +/- 0.5mm, depending on the complexity of the profile and the specific requirements of the customer.The maximum section size that can be achieved for extruded aluminum profile depends on the capacity of the extrusion press and the die design. The largest section size that can be extruded is typically around 600mm x 600mm, but this may vary depending on the specific extrusion press and H13 extrusion Mould die used.Sprinf back behaviors of exrtruded 6063 aluminum profile in subsequent muti-stage manufacturing processes.The process for manufacturing automotive extruded aluminum profiles is a multi-stage process, which includes porthole die extrusion, aging treatment, bending, and electrophoretic painting. Prediction and reduction of springback are essential in quality control of bent profiles. However, existing researches related to springback issues were mainly focused on bending process stage. This study aimed to investigate the spring back behaviors of extruded aluminum profile during the whole manufacturing process by numerical simulations with experimental validations. Formation mechanism and rule of springback for aluminum profile at different process stages were revealed. The optimum process route for manufacturing bent aluminum profiles was proposed. The research results reveal that compared with the transient bending region, the springback of aluminum profile during bending process induced by the finished bending region and two straight regions is relatively small. Springback angle increases with increasing bending angle and aging time. After bending tools unloading, the stresses of the two straight zones are almost completely relaxed. However, large residual tensile and compressive stresses exist in the material adjacent to the neutral layer of aluminum profile in transient and finished bending regions. Consequently, residual stress relaxation causes additional springback of bent profiles during subsequent heat treatment processes. The additional springback angle shows linear correlation with bending angle and parabola correlation with aging time. The total springback angle is minimum for process route 3 that extruded aluminum profile is firstly bent to required shape, then treated by artificial aging and finally treated by electrophoretic painting.
