What Entails Manufacturing Of Aluminum Profiles?

Extrusion is the primary method for making a wide range of aluminum profiles.

It is quite an intensive process, which involves the following phases;

Profile designs take place with the aid of dedicated computer software by documenting the shape, machinability, dimensions and material characteristics.

Billet is cast in an electric arc furnace with aluminum scraps and sliced into idea sizes to match the required profile length.

Preheating of the billet takes place at 900°C, and it intends to soften the material to easily for it through a die.

At this point, the ram exerts pressure on the billet to actuate the actual extrusion process.

Intrinsically, a distinctive extrusion machine with a hydraulic press can exert compression of about 15,000 tons on the billet and die.

Regularly, higher pressure makes the machine to produce more extrusion.

Even so, since there is container wall restriction, the die becomes smaller and wider until it can hardly enlarge anymore.

Hence, the molten aluminum forces its way out through the die’s opening to form a profile.

Frequently, the die opening sizes and billet are what determine the extruded profile length.

This type of aluminum profile may be passed through a cooling bath as it gets out depending on type of alloy used.

Essentially, cooling is imperative because it allows the profile to retain enough metallurgical characteristics in the metal.

Immediately the material cools, you may straighten any twisted or bent part using a stretcher.

When the extrusion process is over, the profile is take through a specified surface treatment segment to obtain an ideal finish.

It is then cut into shorter lengths based on precise dimensions of your application demands.

Also, you may take the profile through aging process to strengthen and allow it to attain ideal elasticity and hardness.

What Options Can You Use To Attach Aluminum Profiles To Surfaces?

You can use the following different techniques to attach aluminum profiles to different surfaces;


Quite a simple and effective method for attaching aluminum profiles on surfaces allowing the separate profiles to attain strong and quick fix.

It merely involves sliding one feature over the other, but the paired profiles must contain male and female features.

Nut Rack

This is a method featuring a channel designed to fit a bolt head or nut tightly between the flats.

In essence, it aims to prevent the bolt head or nut from spinning.

In an ideal world, you can use numerous clips in a single track and position easily.


Here, the method has lead-in barbs that allow top extrusion to simply slide and clip over the bottom one.

Aluminum metal has a natural flex providing a positive snap.

Notably, the barb without reverse chamfer would easily form a permanent snap-fit.

Screw Port

Relatively popular and often used with self-tapping or threaded screws.

It guarantees a robust fix and also allows easy disassembly.

Corner Cleat

It is arguably the most suitable method for fitting two identical aluminum profiles at a specific angle.

Most aluminum profiles have a channel enabling the cleat made from a different sheet steel or metal profiles.

Generally, the cleat tends to have a few barbs on either side, but you can include screws to fix the it in position.


It is commonly used in fixing aluminum profile windows and doors since it allows movement.

What Are The Core Technical Specifications Of Aluminum Profile?

Many applications across residential, commercial and industrial sectors use a wide range of aluminum profiles.

This popularity is influenced by various technical properties of this component, which include the following;
