How Has The Aluminum Extrusion Affected The Manufacturing Industry?

Extrusion may be a process to create objects of a hard and fast profile. Material is pushed at a die of the required cross-section.

About Aluminum Extrusion

Aluminum extrusion may be a process by which aluminum alloy material is forced through a die with a selected cross-sectional profile. A powerful ram pushes the aluminum at the dice, and it emerges from the die opening. When it does, it comes calling at an equivalent shape because the die and is pulled out along a runout table.

What Kinds of Shapes Can be Aluminum Extruded?

There are three main types of extruded shapes.

  • Solid, with no voids or openings (like a rod, beam, or angle).
  • Hollow with one or more openings (i.e., square or rectangular tube).
  • Semi-hollow, with partially void (i.e., a “C” channel with a narrow gap)


There are ten steps of aluminum extrusion.

  1. The Extrusion Die is ready and Moved to the Extrusion Press.
  2. An Aluminum Billet is Preheated BeforeExtrusion.
  3. The Billet is then transferred to the Aluminum Extrusion Press.
  4. The Ram pushes the material into the Container.
  5. The Extruded Material Emerges Through the Die.
  6. Extrusions are also guided, Along with the Runout Table and Quenched.
  7. Extrusions are Sheared to Table Length.
  8. Extrusions are Cooled to Room Temperature.
  9. Extrusions are moved to the stretcher and then stretched into alignment.
  10. Extrusions are next moved to the Finish Saw and move Length.

Good Aluminum Extrusion Design Practices

  • Balanced walls.
  • Avoid/minimize hollows.
  • Great tapers.
  • Practice symmetry/minimize asymmetrical detail.
  • Use grooves, webs, and ribs.
  • Minimize perimeter/cross-section ratio.

How much does aluminum extrusion cost?

The typical tooling cost for an extrusion die is $900 to $1,500, and therefore, the average time interval to supply an extrusion is about 10 to 14 days. Other processes such as roll forming, injection molding, and die casting can take up to 20 weeks.


  • Lightweight
  • Strong
  • High in strength – to – weight material.
  • Reflective
  • Seamless
  • Easily tailored


  • Size variances
  • Product limitations

What are aluminum extrusions used for?

Aluminum extrusion could also be a way to transform aluminum alloy into objects with a definitive cross-sectional profile for an honest range of uses. The extrusion process makes the foremost of aluminum’s unique combination of physical characteristics.

What are the primary extrusion defects?

The typical defects in the extrusion process are Improper System Engineering/Installation, Improper Operation, Resin Defects, Improper Materials Addition, Surging, Poor mixing, Melt toughness or fracture, Overheating, Moisture release, Trapped air, Contamination. Wrong Clamps used or Clamps too tight.

Tips for ImprovingExtrusion Efficiency and Preventing Problems

  • Adjust the feed throat temperature.
  • Maintain a consistent regrind form.
  • Excellent screws are used when processing polymers to attenuate degradation.
  • When starting an extruder with an empty screw, begin turning the screw slowly, and then introduce the resin by opening the feed throat slide gate.

The uses of aluminum extrusion in product design and manufacturing have increased significantly in recent decades. It has flourished in many manufacturing industries and made aluminum usable.
