The Process of Aluminum Extrusion

2015-06-18T15:33:41+00:00May 18th, 2011|

“Extrusion” is often defined as the process of shaping a material, such as aluminum, by forcing it to flow through a shaped opening in a die. The extruded material emerges as an elongated piece with the same profile as the die opening. 

In thinking about the extrusion process, consider a Play Doh Fun Factory and how it might work. Think of the Fun Factory as the extrusion press, the handle as the ram, the shape bar as the die, and the Play Doh as the aluminum billet.

The first step is to choose the desired shape and color. Think of the shape as the die which will be used and the color as the temper and alloy needed. Next, the Play Doh is inserted into the holding chamber and pressure is applied to the handle, which forces Play Doh through the shape. In an extrusion press, pressure is applied to the billet by the ram where the dummy block is attached to the end of the ram stem.

When Play Doh begins to emerge, it has effectively been “extruded”. The same principles apply to extrusions from aluminum billets but considerably more detailed and sophisticated technology are involved.

Press size determines how large of an extrusion can be produced. Extrusion size is measured by its longest cross-sectional dimension (i.e. its fit within a circumscribing circle). A circumscribed circle is the smallest circle that will completely enclose the cross section of an extruded shape.

The most important factor to remember in the extrusion process is temperature. Temperature is most critical because it gives aluminum desired characteristics such as hardness and finish.

Tips for Extrusion Design

2015-06-18T15:33:41+00:00May 4th, 2011|

When you start designing a new extruded aluminum piece, there are several important factors you should keep in mind.  Here is a quick list of design tips to get you started:

1. Know the circle size of your vendor.  If you don’t know the extruder’s limitations you’ll likely design a part they can’t produce and end up redesigning the part or shopping it around to find a fit.  Additionally, the greater the circle size the more tolerance becomes an issue.  Start working with an extruder early on.  Some offer engineering support and some don’t.

2. Evaluate your tolerance requirements to that which your extruder can support. You can look to aluminum.org for design guidance in addition to your extruder.  Aluminum.org’s information is somewhat technical however.  So, for quick answers call/email your extruder or you can use Qualified Vendor’s quote service to find suppliers.

3.  If your parts require secondary machining, make sure you design in indexing features.   This can be as simple as an extruded groove in which the machinist can use to take a hole dimension off of.

4.  Wall thickness – design them as uniformly as possible.  This will prevent voids in the extrusion.

5.  Designate critical and cosmetic surfaces. This will prevent unintended marring of critical surfaces.

6.  Heat sinks – as a rule of thumb, fins should not exceed 10:1 length to thickness.

7.  Screw bosses – keep a 60 degree opening otherwise the die will require a torpedo which will significantly affect the cost and life of the die.  Use your machinery’s handbook for McMaster Carr for screw hole guidance.  I recommend self cutting/starting thread forming screws.  They’re inexpensive and yield a great strength, so much so that you need to be careful when inserting them so you don’t shear off the heads – use a driver with a clutch.

8.  Make transition areas smooth with gentle radii.

9.  Select the proper alloy for your application and make sure your extruder can use this alloy.  Many only work with one or two series of aluminum – 2XXX or 6XXX are most common.

10.  Lastly, consider your finish.  Design with appearance and performance in mind.  Don’t forget that the parts have to have secondary operations, packaged and shipped.  Many finishes like anodizing will change your tolerances.  Keep this in mind.  Likewise, if you’re going to powder or wet paint your finished parts make sure you designate which features (holes, grooves, etc.) need to be masked off to prevent paint contamination.  This may affect your final assembly.

Aluminum Extrusions are used for defense systems

2015-06-18T15:33:41+00:00March 31st, 2011|

So just how do aluminum extrusions factor into the military world you may ask? Well since extruded aluminum can be found in many aspects of defense systems, I will start by exploring how armor, armored cars, decking and missile containers all use extruded aluminum. One can see that when quality aluminum extrusions are used for all aspects of defense, the defense systems in place will be more thorough.

Military and armored vehicles have to stay upright even when there is a massive use of force against them. Aluminum extrusions also are used for launch pads! It is pretty exciting to find out that aluminum extrusions are used for such an exciting aspect of military defense. Next time you are reading up on technological feats within the military there is a chance that there is some form of extruded aluminum being used!

Inside Track A Talk With SuppliersReveals ‘Pain Points’
Aviation Week & Space Technology

March 21, 2011, p. 16
By: Michael Mecham

Printed headline: From Ohio to Arkansas

Ohio is the No. 1 U.S. supplier toEADS/Airbus($4.3 billion in annual sales) and No. 2 toBoeing($4.8billion), after California.General Electric’s engine works in Evendale and Peebles account for much of that, but there are thousands of other suppliers spread across the state, some dating to World War II,when the government pushed aircraft production inland to make it less vulnerable to attacks. We recentlyvisited with Ohio’s suppliersat a roundtable in Cleveland hosted by Aviation Week and the OhioAerospace Institute. Not surprisingly, workforce topped the list of today’s pain points.

Alcoa Forgings and Extrusions President Eric V. Roegner reports having to compete with banks andconsulting companies for top college graduates. He’s honed his pitch to include topics that will appeal toyoung professionals, such as green and sustainability. Stephen P. Johnson, director of process technologyat Timkin Co., has had two senior technical positions open for two years. He also worries about how hewill replace his company’s aging baby boomers. And Fred Lisy, the president of tiny Orbital Research,laments that he spends time and money training young engineers, only to lose them after a few years tobigger companies.

Lisy and other small suppliers also complain about their difficulty in finding sufficient financing tosustain them through the program delays that are endemic in aerospace. Financing worried larger contractors, too. With cuts in U.S. and European defense spending, how can they take a chance on long-lead R&D investments for next-generation products that may not be funded?

Then there’s China, whose aerospace market the group views with a mixture of excitement andapprehension. “If you’re an engineer and you’re interested in working in China, we’d be interested inspeaking with you,” says Christopher Farage of Parker Hannifin,a major contractor on China’s newComac C919 jet.

But Ohio’s suppliers worry that the Chinese government’s push to create a domestic aerospace and defense (A&D) base could one day squash them. Roegner points to Chinese investments in new forges that could compete with Alcoa. If Boeing and Airbus find viable suppliers in China, “the game is on,” he says. Is the challenge China poses to U.S. technological leadership being taken seriously enough? “You kind of wish that the U.S. government would wake up,” says Roegner.

But China is not the only challenge for the Ohioans. Across Lake Erie, Canada has instituted a tax credit of up to 48% for companies creating R&D jobs there. Then there are competitors springing up in lower-cost, non-union southern U.S. states. Farage says higher tax and labor costs push his company’s costs40% above some of his competitors. “Ohio is not cost competitive,” he complains.

If you talk to one of those southern competitors, Taber Extrusions, the competitiveness answer comes not just in lower costs but specialized skills. Privately held and with 250 employees, Taber makes large, long and wide aluminum alloy extrusions in numerous rod, angle, hollow and beam shapes. It uses multiple forming technologies, including friction stir welding, and focuses on high-value, intricate small-lotcontracts. Taber’s 8,600-ton press in Russellville, Ark. (shown), can, for instance, extrude a 100-ft.-longwing stringer that is so large that special routing is needed to rail ship it.

Its answer to low-cost China is high-value American expertise. “We specialize in hard-to-make things,”says sales manager Steve Althardt.

A Silver Supplier Excellence award winner from Boeing, Taber also serves Gulfstream, Cessna andLockheed Martin’s aircraft programs. It has felt the downturn in general aviation but balances its aviation portfolio with defense and naval contracts—the MRAP mine-resistant vehicle, M-113 Bradley andLittoral combat ship among them. And Taber has a niche as a major supplier of compound aluminum bow risers for archers.

Naturally, the company is watching the evolution of composite structures in aircraft. “It doesn’t make us happy that aluminum will decrease in the aircraft segment,” he says. “But there’s a lot of aluminum that will be used in airplanes for years to come.”

Aluminum Series: The Battle has begun… 5000 vs. 6000 series

2024-01-27T21:20:53+00:00August 21st, 2010|

It has become quite the battle, 5000 series vs., 6000 series. And who is competing for the title you ask? Well, none other then aluminum extrusions. It is important to understand the differences and key performance factors in marine and other military applications. 5000 series has always been the top choice for naval engineers in order to enhance overall structure integrity.

While counter-intuitive, the reality is that the 6000 series does not win in strength, far from it. In fact the 6000 series loses forty two percent of its ultimate strength whereas some in the 5000 series only lose three percent ultimate strength.

Overall, the advantages of the 5000 series are never-ending! Click Here to view the superiority of the 5000 series in Taber’s 5000 series vs. 6000 series aluminum extrusions. understanding key differences and key performance factors in marine and other military applications.
