Understanding The Methods And Process Of Aluminum Extrusion

Aluminum extrusion is the method of forcing aluminum alloy material through a die with a predetermined cross-sectional shape. The aluminum extrusion is pushed through the die by a strong ram and emerges from the die gap. Extrusion is the method of forcing material, such as aluminum, to flow through a die to form it. Extruded material appears as an elongated piece with a profile similar to that of the die opening.

An introduction to the method of aluminum extrusion

  • Identifying a customer’s profile

Richardson metals receive a sketch of the profile that needs to be extruded from the consumer. At this point, we’ll see if we’ll be able to manufacture the design while remaining within the customer’s requirements and tolerances.

  • Creating billets out of aluminum

After the dies have been manufactured, the extrusion process will begin. Cutting the aluminum into billets will be the first step.

  • The aluminum billets are heated

The billets are also preheated between 850 and 925 degrees fahrenheit, which is hot enough to crack the metal but not strong enough to turn it into molten lava.

  • The billets are transferred to a loader

After being heated, the billets are loaded into a loader and lubricated to keep them from attaching to the extrusion equipment.

  • The billets are extruded

The billets are immediately extruded after being loaded into the loader. A ram moves against one end of the billet to drive the other end to the die indirect extrusion processes.

This process is repeated until the whole billet is passed through.

Excessive extrusion pressures and speeds may also cause the metal to break at thin edges or sharp corners. This is due to the metal’s compressive strength weakening at extremely high-generated heat. Contact between the metal and the die-bearing surfaces is liable to be incomplete and irregular at such speeds and temperatures. Any inclination toward waves and twisting in the form is amplified.


  • Specifying the Implement Industry is one of the characteristics.
  • Wherever possible, uniform metal depth
  • Tolerances can be calculated using metal dimensions.
  • Consider the surface finish when designing your design.
  • Using Webs to make transitions smoother.
  • Ribs can be included.
  • Sharp Corners Should Be Avoided
  • Index Marks Should Be Used

Extrusion is a shaping technique used to create parts and products with a defined cross-sectional profile. It entails ramming softened raw material through a die designed to produce the desired profile. The substance takes on the form of the die’s openings as it passes through it. The semi-finished portion cools and hardens after the billet aluminum extrusion falls through the die. After that, the material can be cut to the desired finished length or specifications for further processing. The size of the press determines the size of the extrusion that can be made. The longest cross-sectional dimension of extrusion, i.e., how well it fits within a constraining circle, is used to calculate its size. The smallest circle that completely encloses the broad swath of an extruded shape is called a circumscribed circle.
