Components of an Aluminum Extrusion Machine

There are various parts that come together to make the aluminum extrusion process possible. Wangeshi Extrusion Machines are no different. While each of these parts has a different role to play, they are all important in making the overall process possible. These parts include:


Hydraulic System

A hydraulic system is the mechanism that drives the entire extrusion system. The machines use electric power drawn from a connected combustion engine or commercial power supply to drive the powerful hydraulic thruster, which is capable of producing thousands of pounds of pressure per square inch with relatively little energy consumption.


Main Cylinder

The main cylinder holds all the associated components of the extrusion press machine that will be activated by the pressure of the hydraulic fluid being pushed and delivered by the hydraulic system.  Because of the intense pressure this component has to endure, it is made of tightly sealed strengthened metal alloys.


The ram is a steel rod that is connected to the main cylinder by a dummy block on one of its ends. When hydraulic pressure is applied on the opposite end, it will transmit it into the container and onto the billet.



The billet refers to the mass of raw aluminum that is fed into the extrusion machine. You can feed the machine with billets of different aluminum alloys, of different shapes, and at different temperatures. Your choices will be determined by the type of extrusion you need and what its final purpose will be.


Dummy Block

Because of the intense pressure that aluminum is placed under in the extrusion machine, there’s a risk of leakages unless precautions are taken. The dummy block is the first line of defense against this possibility, as it is a tight-fitting block of steel that is attached to the ram stem so that it seamlessly seals the billet inside and prevents it from leaking out.




The billet being extruded will be placed in the container as it is pushed against the die by the hydraulic-powered ram.


Die Assembly (Tool Stack)

The die assembly refers to the collection of dies that are placed in the extrusion container to determine the type of extrusion produced. To get solid extrusion, you will use a die assembly comprising a die, die ring, bolster, sub-bolster, and backer. For hollow extrusions, you will install a die mandrel, die ring, bolster, sub-bolster, and die cap.


Die Holder and Lock

The die holder and lock work together to hold the entire tool stack securely in place during the extrusion process.


Billet Oven/Log Oven

In some cases, the aluminum billets/logs will need to be heated to certain temperatures so that they are more malleable. Extrusion machines that come with log shears will have log ovens, while others come equipped with billet ovens.


Log Shears

These shears are fitted in machines with log ovens to cut billets to the desired lengths.


Die Oven

Where required, the die oven can heat raw aluminum to temperatures ranging from 800 degrees Fahrenheit to 900 degrees Fahrenheit for about 5-7 hours before being extruded.


Butt Shear

Once an extrusion cycle is completed, there will be some non-extruded portions of the billet left in the container. Butt shears are responsible for cutting off these parts, where the leftover oxides remain once the ram has pushed the billet through.


Press Lead-out Table

This section of the machine supports the extruded material as it runs from the die to the run-out table. Such a section is important because it prevents the extruded aluminum from becoming deformed under the weight of gravity, more so since it might still be soft and malleable due to being preheated.



The cradle keeps the billet in place while it’s being pushed through the die. Cradles also contribute significantly to the combined stability and steadiness of the entire machine, which is vital for the production of accurate, precise extrusions.


Run-out Table

Run-out tables are metal tables placed immediately at the exits of the lead-out equipment to help support and guide the extrusion as it leaves the press.



The canister is designed to guide the billets as they leave the die. To facilitate this, they have the same hole pattern as the dies. Without the canister, extrusions might leave the die at the wrong angle, potentially distorting and destroying the final result.


Tie Rods

These rods are set up to hold the front and rear press platens in place. They are critical for maintaining the proper alignment of the machine’s main moving parts.


The Advantages of Using Extruded Aluminum

There are various benefits and advantages that come with using extruded aluminum in various industries. Thanks to its various qualities and characteristics, it is considered a superior raw material in a plethora of industries. For this reason, aluminum extrusion machines continue to be highly popular with aluminum product manufacturers worldwide. The list of advantages that aluminum extrusion products come with include:



Aluminum metal can be recycled almost indefinitely, making it one of the most environmentally friendly industrial metals available. You can produce aluminum extrusions using recycled aluminum without a corresponding degradation in the product’s quality, functionality, and aesthetic appeal.


Ease of Use

Aluminum extrusions can make any fabrication and assembly projects you have significantly easier than they would be using other metals, which translates to lower production costs and more efficient time management.


Short Lead Times

You can get aluminum extrusions to your intended market considerably faster than you could with other metals, thanks to the easy tooling methods available. It’s much easier to accomplish a production process involving prototype development, testing, and complete product launch. This rapid developmental lead time makes aluminum relatively more economically viable for various applications.



Sections of extruded aluminum can be seamlessly connected and formed into single pieces without the need for mechanical joining, which can be complicated, time-consuming, and the cause of potential weak points.


Easy Tailoring

Even though there is a wide variety of standard aluminum extrusions you can choose from for your project, aluminum extrusion allows you to create new designs that fit your individual functional, aesthetic, and manufacturing requirements. Because of this easy tailoring quality, extruded aluminum is favored by many fabricators and manufacturers.



Once you treat aluminum extrusion with highly reflective surface treatments, it can be transformed into an attractive lighting option for applications where shielding is required against infrared radiation, radio waves, and light.


Non-Toxicity and Non-Combustibility

Even at extreme temperatures, aluminum will not burn or produce toxic fumes, and these qualities make it ideal in situations where safety standards are a priority, such as the automotive industry.



Aluminum will not acquire magnetic charges when exposed to magnetic materials, making it ideal for use in electronics and high-voltage applications, which often come with electric activity.


Thermal Conductivity

Aluminum conducts cold and heat better than other metals based on its overall cost and weight. These factors make it an excellent choice for people creating appliances and structures that make use of heat dissipation and heat exchange.


Thanks to the flexibility of extruded aluminum, designers can optimize the heat dissipation that takes place in components such as heat sinks, housings, and so on.


Electrical Conductivity

When we consider it on a pound-for-pound basis, aluminum is almost twice as conductive as copper, and this makes aluminum an incredibly cost-effective solution for the creation of bus bar distribution components and connectors.



Thanks to its ability to flex and spring back under the weight of heavy loads and pressure, aluminum can be a useful component in applications where shocks, loads, and impacts might come into play, such as the automotive and building industries.


Aluminum is approximately one-third the weight of other comparable metals such as brass, copper, steel, or iron. Thanks to this quality, it is much easier to handle, transport, and manipulate. Its lightweight quality makes it invaluable in weight-sensitive industries and applications such as transportation and engineering.


Final Thoughts

In every industry you can think of, the quality of the materials you use will have a direct correlation to the results you achieve. The importance of quality raw materials is even more significant in areas where metals are put to use, such as the building, construction, automotive, and fabrication industries, among others.
