Case Study: Lean Manufacturing at Eagle Alloy

Posted by Jeff Cook on 2018 Mar 27

Eagle Alloy, Inc. was founded in 1979 and quickly grew from a short-run facility to a medium-to-high-production steel foundry. Despite the company’s success, its founders were not satisfied with the status quo. Having heard of developments in lean manufacturing, they decided to implement these tools in hopes of achieving greater efficiency, stability and quality throughout the production process.

5S: The Beginning

As with many production facilities beginning to experiment with lean manufacturing, Eagle Alloy started with 5S. 5S is easy to adapt to just about any environment, and the key to lean is customization. Every lean tool must be adapted to the particular type of production, to the size of the company and to the facility's space.

Casting Aluminum: Comparison of Methods

Posted by Jim Smith, Jr. on 2018 Mar 22

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.

CNC Metrology: What Can a CMM Measure?

Posted by Nik Seyferth on 2018 Mar 7

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".

Aluminum Casting in Practice: A Case Study of Cast Aluminum Fan Blades

Posted by Jim Smith, Jr. on 2018 Feb 21



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.
