Aluminum Shape Manufacturers and Companies

Extruded aluminum shapes are highly versatile and can be designed for specific applications such as fitness machines, wall siding, structural applications, car bumpers, window frames, electronic components, hardware joints and light building frames. Serving industries including construction, medical, office furniture, industrial manufacturing and transportation, aluminum extrusion shapes are lightweight and flexible.

Aluminum channels and profiles are commonly used in:

Vehicles

Such as trains, SUVs, semi-trucks, and cars for parts and components including, panels, window panes, runners, bumpers, and chassis.

Machinery and Industrial Equipment

Such as scaffolding, process, and mining equipment use extruded aluminum tubing, shapes, and profiles as lightweight, durable equipment components.

Architectural and Construction Industries

Use profiles extensively, whether it be for practical applications, such as for structural and ceiling beams, or aesthetic applications, such as decorative trim and window paneling.

Capable of Being Extruded Through Complex Dies into Close-Tolerance Shapes

Small extruded aluminum shapes are frequently fabricated into medical and electronics components, such as heat-absorbing and dissipating heat sinks.

The right aluminum extruded shape will cost the least amount of money, be simple to manufacture, and fit the structural requirements of each application. In today's world, the best way to do this is through the functional approach. The functional approach to extrusion design uses common sense to create the design. Rather than thinking about what shape the structure needs to be, the first thought is what the piece will need to do. After determining the use of the structure, the engineer should then consider what shapes provide that support, how the elements would relate to one another in a 3D environment, and then create the design. Thinking of the design process this way eliminates the limitations of current designs and prevents in-the-box thinking that can reduce the effectiveness of new designs.

Aluminum extruded shapes are commonly formed from stock aluminum using three types of extrusion processes; each of these processes have their own benefits and drawbacks. During the extrusion process, round aluminum stock called "billets" or "logs" are pressed by a ram through a die, which is a hollow profile that shapes the aluminum into a specific extruded shape as the billet is squeezed through. Extruded aluminum shapes can be made using three different types of extrusion process: cold extrusion, warm extrusion, and hot extrusion. In cold extrusion, aluminum billet is pressed through the die at room temperature or near room temperature. Warm extrusion, or forging, is done on billets brought to temperature ranges between 800 and 1800 degrees F. Hot extrusions are performed on aluminum that has been fully plasticized by heat and is often performed in a vacuum to avoid oxidation.

Aluminum can be extruded through the die using two different methods of extrusion: indirect extrusion and direct extrusion. Direct extrusion holds the die stationary while the ram forces the aluminum alloy through the die opening, while indirect extrusion holds the die stationary as the hollow ram moves into the stationary billet from one end, forcing the metal to flow through the die. After an aluminum extrusion shape has been extruded, it is straightened by a stretcher. Also, aluminum shapes can be considered ”green” products because they are 100% recyclable and recycling aluminum requires only 20% the amount of energy used by acquiring virgin materials; this energy savings is converted into a significant cost savings.
