The Process Of Making Aluminum Profiles
Aluminum extrusion is defined as a process for shaping a material, forcing it through an shaped aperture in a die. The aluminum extrusion process involves forcing the material in an aluminium alloy through a die with the exact cross-sectional pattern and dimensions of the end product. Products made from the shapes produced by aluminum extrusion are quite stable and strong, especially if fabricated in combination with other metals, such as magnesium and silicon.
There are several components involved in an aluminum extrusion, including a production mold, which is the shape that will produce the aluminum. The die, in the form of a circle, is made from steel, which is preheated prior to the Aluminum Extrusion process in order to reduce wear and ensure an even metal flow. Extrusion is the current process where aluminium billets are heated and forced through shaped holes of a die.
The design is formulated, an extrusion die is made, the manufacturing schedule is laid out, and an aluminum billet is heated and forced through a die to produce the desired design. The aluminum extrusion would take place in an automated manufacturing line, which would include the heating of the billet, extrusion, cooling, straightening by tension, cutting, and other processes. Aluminum extrusion is pretty cool, you can end up with different shapes of products which can be heated treated, machined and finished according to your specifications.
The overall process involves heating a sheet of aluminum, and passing it through an aperture of shape into the die. The process involves forcing the heated billet, which is raw material, through a series of predetermined dies using heat and pressure applied by a ram. Forming In extrusion processes, aluminium tubes can be hot extruded, cold extruded, or warm extruded, which all extrude aluminium through the die, though with different temperatures.
To produce structural products from aluminum extrusion, the aluminum billets need to be heated to 700-900 degrees F -- after they are melted, the metal can be fed through a die. From there, a heated billet moves into a tunnel heater, which heats aluminum materials up to about 900 degrees Fahrenheit, though exact temperatures vary depending on aluminum characteristics. Once all components are heated to their proper temperatures, the aluminum billet is lubricated and moved mechanically into an extrusion machine.
Because the material is processed only for shear and compression strengths, the aluminum extrusion press is capable of producing even the most complex cross-sections from the most delicate materials. The building industry, especially, relies on products made from aluminum extrusion, but structural aluminum components can be found in maritime applications, automotive, and aiding in the machining processes of industrial machines themselves. Regardless of the specific application or industry involved, the aluminium extrusions produced by aluminium extrusion companies are extremely helpful for developing products that allow exceptional functionality and beauty.
