Xsection 8 application7/21/2023 The dimensional tolerance of cross section should be determined according to the machining allowance of the aluminum profile, the conditions of use, the difficulty of extrusion of aluminum profile, the alloy grade and the shape of the position. The dimension tolerances of cross section If the radius is too small, stress concentration will occur on the mold, while the concave right angle is prone to wear at the entrance of the die hole.ħ. The transition radius on the convex right angle is very important. It is even difficult to extrude, and even if it can be extruded, it is difficult to extrude qualified aluminum products. When the cantilever beam is thin and deep, the mold breakage rate is greater. In terms of the cross-sectional shape of the aluminum profile, the part that is surrounded by three sides and one side is open is called the space area.įrom the perspective of the mold, this space is a cantilever beam. The wall thickness is related to the difficulty of extrusion of the alloy. The minimum value of the wall thickness of a particular aluminum profile depends on the size of the circumscribed circle diameter of aluminum profile, the alloy composition and shape factors, etc. In order to make the extrusion coefficient have a certain amount of deformation, and at the same time not be difficult to extrude, it is very important to choose the extrusion coefficient reasonably.Ĥ. The complexity of cross-sectional shapesĪccording to the cross-sectional shape of aluminum profiles, it can be divided into three categories, namely solid profiles, semi-hollow profiles and hollow profiles. Under normal circumstances, the aluminum profile with the largest circumscribed circle that can be extruded on each extrusion press is not fixed, which is related to the diameter of the extrusion cylinder.Ģ. The larger the circumscribed circle, the greater the extrusion force will be required. The cross section size of aluminum profile is measured by the circumscribed circle. Here are 8 top factors for cross section design of aluminum profiles The possibility of aluminum extrusion should be considered when designing the cross section of the aluminum profile. The production of aluminum profiles by extrusion is a method that saves metal and has high production efficiency. 8 top factors for cross section design of aluminum profiles 8 top factors for cross section design of aluminum profilesĨ top factors for cross section design of aluminum profiles, How is the aluminum profile cross section designed?
