Aluminum profiles are made from hardened steel, making it possible to use the same profile multiple times without fear of degradation. Essentially, a profile produces continuous high tolerance components consistently. Common standard profiles include I beams, angle brackets, and tubes.
Aside from the standard profiles, unique profiles are created to meet the needs of specific applications. In those cases, customers supply a computer-created rendering or work with extrusion engineers to develop the desired profile.
Manufacturing a Profile
Profiles are produced from softened aluminum billets forced through a die. The two types of extrusion are cold and hot. In both cases, a hydraulic press or ram forces an aluminum billet through the die. The extrusion process requires completing a set of steps where the temperature of the process is closely monitored.
Preparing the Die
The first step in the process is the creation of the die, which is a round piece of hardened steel. To ensure even metal flow and maximize the die's life, it is heated to 932 °F (500 °C) before being loaded into the extruder.
Heating the Billet
For hot extrusion, the billet, which is a few feet in length, is heated to a point where it is soft but not molten, up to 932 °F (500 °C).
Loading the Billet
Before the billet is loaded into the extruder, a release agent is applied so that the soft aluminum moves through the die smoothly and evenly.
Applying the Pressure of the Ram
The hydraulic ram of an extruder can apply 15,000 tons of pressure as it slowly moves the billet toward the die. During the ram's movement, pressure builds as the softened billet expands to fill the walls of the extruder.
Aluminum Emerging from the Profile
The increasing pressure forces the softened aluminum through the die. The emerging shape is the full form of the profile.
When the extrusion exits the die, it is gripped by a puller that guides it along the runout table at its exit speed. The profile is quenched and uniformly cooled on the runout table using water or fans placed along the table.
Once the extrusion reaches the end of the runout table, it is sheared for ease of handling and moved on to the next step. Every aspect of the extrusion process includes a close and careful monitoring of the extrusion's temperature to ensure the quality of the extruded product.
Although the extrusions have been cooled, they are not sufficiently cooled to be fully processed. For further cooling, they are moved to a cooling room, where they remain until they reach room temperature.
During the extrusion process, the profile's natural twisting and curving must be corrected by stretching. The process requires that both ends of the extrusion be tightly gripped and pulled until it is straight and meets design specifications.
The table length extrusions that have been cooled, stretched, and hardened are ready to be trimmed and cut into usable lengths, normally eight to twelve feet. At the point of finishing, the extrusions match the necessary tolerance of their design and are sufficiently tempered. For further tempering, the extrusions are moved to an aging oven.
Types of Profiles
The determination of what profile to use is dependent on the application for which it is designed. Profiles come in different thicknesses, types of aluminum, and shapes, making them highly adaptable and versatile, and are manufactured from several deformable aluminum alloys.
Hollow profiles have a cross-section that forms a hollow cavity.
Solid profiles are completely open, with no closed sections, and are available in many different forms.
Open End Profiles
Open-end profiles are a combination of hollow and solid profiles.
Semi-enclosed profiles are partially open and partially closed cavities, such as a rectangle profile with an entrance on one end. All forms of profiles are required to meet specific geometrical tolerances and dimensions, which are defined by the computer rendering.
Categories of Difficulty for Profiles
All forms of profiles are required to meet specific geometrical tolerances and dimensions, which are defined by the computer rendering.
Shape Factor – The shape factor is the area of all surfaces of the profile
Complexity – The complexity of profiles begins with the letter A, the least complex, and continues to the letter N, the most complex.
Maximization of Aluminum – The maximization of a profile relates to the most efficient use of aluminum.
Price – The price of a profile directly relates to its complexity.
Choosing the Proper Aluminum Profiles Manufacturer
To make sure you have the most productive outcome when purchasing Aluminum Profiles from an Aluminum Profiles Supplier, it is important to compare at least 4 or 5 Companies using our list of Aluminum Profiles manufacturers. Each Aluminum Profiles Supplier has a business profile page that highlights their areas of experience and capabilities and a contact form to directly communicate with the manufacturer for more information or request a quote. Review each Aluminum Profiles business website using our proprietary website previewer to get an idea of what each company specializes in, and then use our simple RFQ form to contact multiple Aluminum Profiles companies with the same message.
