Aluminum can be shaped through a wide variety of process, including:

• Casting
• Extrusion
• Forging
• Rolling

For any type of metal, casting is arguably the most versatile of all of the forming processes, and results in the greatest variety of parts. In fact, the US Department of Energy estimates that over 90% of all manufactured goods contain metal cast products.

The same casting techniques used for other metals can be applied to aluminum, but some of the most popular methods used with aluminum are permanent mold casting, greensand casting and die casting.

Two Eagle Group companies, Eagle Alloy, Inc., and Eagle CNC Technologies, Inc., have posted a series of personal bests and significant improvements across the board.

As you can see below, Eagle Alloy's achievements in 2017 include:

• 96.4% delivery – 2nd best in company history
• 1.87% scrap – BEST in company history
• 2.64% returns – Best in last 10 years
• 97.4% audit score – Best in last 8 years
• .27 PPM resulting in complaints – BEST in company history

Coordinate Measuring Machines, known more often as CMMs, are a staple of industrial metrology. Of the thousands of variations of CMMs, you're likely to encounter at least one version in every manufacturing quality control department. You might not recognize it at first because CMMs can look like, well, pretty much anything–but in any form, these hard-working machines allow manufacturers to accurately measure a long list of product characteristics.

Sure, manufacturers could still measure their products the old fashioned way–with a good set of calipers and a lot of trigonometry–but in today's competitive environment, we need to take measurements in minutes, not days. We also require superior accuracy, sometimes down to .00005".

Eagle Aluminum Cast Products, Inc. recently published an ebook offering insight into manufacturing with aluminum.

Manufacturing with Aluminum: History, Forming Techniques and Best Practices draws on decades of experience, taking a holistic approach to aluminum manufacturing. Weighing in at just under 25 illustrated pages, the ebook aims to fill a gap between online resources and textbooks. According to Jim Smith, Technical Manager at Eagle Aluminum, “We want to make sure anyone curious about aluminum can get all the basic information they need, without searching all over the Internet or going back to school.”

The Eagle Group will be at Design2Part 2018 in Grapevine, TX, March 14-15. If you're in the area or interested in going, we can get you in the door for free!

The event will be the largest contract manufacturing trade show in the region, with over 300 categories of manufacturing services on display. Design2Part is the place to be if you want to:

• Find quality suppliers
• Discover new technologies
• Solve manufacturing problems

A major manufacturer of ventilation systems contacted Eagle Aluminum Cast Products, Inc. when demand was growing and they were ready to make a change.

The customer had already been producing 48” fan blades for agricultural use through green sand casting, but they’d outgrown that method. Demand projections suggested that permanent mold casting would yield lower per-part costs, with the added benefit of greater consistency.

Years later, EACP still produces fan blades for the customer through the process of permanent mold casting. Demand has increased even more, and product offerings have become more diverse. Read on to learn how EACP handles the design, production and delivery of this cast aluminum fan blade.

Erik Deckers, a marketing speaker at this year’s Metalcasting Congress, has co-authored a book with Kyle Lacy, Branding Yourself: How to Use Social Media to Invent or Reinvent Yourself, third edition.

The book is a guide to the major social media platforms, and how you take charge of your brand on those platforms.

We need to listen to Deckers’ expertise. He knows how you can make these social media platforms work for you, and he can help you decide which ones will be the best for you. 

Investment casting, sometimes known as lost-wax casting, is a metal forming method known for its ability to produce parts with tight tolerances, complex inner cavities and accurate dimensions.

As we discussed in our Introduction to Investment Casting post, the basic technique has existed for millennia. Over the years, innovations in equipment and methodology have kept pace with demand. Today, investment casting is one of the most popular forms of metal casting.

Read on to learn more about the unique process of investment casting.

Lean Manufacturing principles encourage maximum efficiency for just about any production facility. Lean Manufacturing is also more of a necessity than ever, with cutthroat competition across the manufacturing industry forcing all players to up their efficiency levels.

If you're worried that your company isn't lean enough, take a look at these five tools from the Lean Manufacturing playbook.

Investment casting is nearly as old as metalcasting itself, with the earliest known examples dating back to 3,500 BC. Before investment casting was invented, metal castings were created using open stone or ceramic molds. Investment casting allowed for much greater detail and smoother finish, vastly expanding the possibilities of metal casting.

Today, investment casting is one of the most versatile methods of metal casting. The process, which is still similar to that used over 5,000 years ago, allows for tighter tolerances, more intricate shapes and smoother surface finishes than other metal casting methods.
