What is Aluminum Extrusion?

Aluminium banishment is a process used to create objects from aluminum alloy. In this manufacturing process, aluminum alloy is pushed through a die to give it a particular cross-sectional profile or shape. Extrusion allows aluminum to be crafted into a variety of finished products and components used across many industries.

The Extrusion Process

Aluminum ingots are heated to their semi-molten state to prepare them for extrusion. A press then pushes this malleable aluminum through a steel die, which gives the aluminum its desired two-dimensional cross-section profile.

Common extrusion shapes include rectangular, square, circular, multi-sided, and specialty profiles. Complex structures can be extruded by using multi-cavity or multi-outlet dies in a single press.

Some key stages in Aluminum Extrusion include:

- Billet heating: Aluminum billets or logs are uniformly heated to between 450°C to 500°C to become malleable. This heating is done using gas-fired or electrical furnaces.

- Container filling: The heated billet is then pushed into the container or chamber of the extrusion press.

- Forging: A reciprocating ram or press pushes the billet through the steel die, which shapes the aluminum. Lubricants help reduce friction during extrusion.

- Sizing: The freshly extruded Aluminum Extrusion is stretched and sized to its desired length and tolerance using rolling or drawing.

- Finishing: Processes such as cooling, cutting to length, and end-product fabrication bring the extrusion to its final form.

Industries that Use Aluminium banishments

Some of the industries that benefit most from aluminium banishment include construction, transportation, machinery, consumer durables, and electrical work. Common applications include:

Construction - Aluminium banishments are structural members in buildings, curtain walls, doors, and windows. Their strength-to-weight ratio, formability, and corrosion resistance make them well-suited for construction.

Transportation - Every mode of transport utilizes aluminium banishments, from frames in cars and trains to aircraft skins and boat hulls. Their light weight helps improve fuel efficiency in vehicles.

Machinery - Intricate extruded aluminum parts serve as structural framework, conduits, brackets, and more in machines across multiple industries. Extrusions help machinery be more durable and lightweight.

Consumer Durables - Items like home appliances, furniture, sporting goods, and electronics rely on extruded aluminum for parts and panels. Its workability allows complex shapes.

Electrical work - As electrical conductivity is excellent, aluminium banishments are conductors, bus bars, pole line hardware
