The wax room is at the heart (and start) of our investment castings. By injecting the wax room with fresh ideas, we’ve been able to greatly improve our pouring efficiency, leading to higher production yields, less downtime, reduced remelting rates, and faster delivery times.

Collaboration Between Casting and Machining to Re-Engineer a Lost Component of a Vietnam-Era Patrol Boat

Muskegon-based manufacturers Eagle CNC and Eagle Alloy put their capabilities to the test when they set out to replicate a key component of a Vietnam-era patrol boat as a steel casting. For the team behind the casting, this project is about more than fixing a boat; it’s about preserving history, honoring the legacy of those who served and sacrificed, and ensuring their stories continue to be told for generations to come.

Dave Fazakerley, Eagle Alloy President and Chief Operating Officer, has played a central role in shaping the company since its early days. Over the course of his career, he has helped guide Eagle Alloy’s growth, build its operations, and foster a culture of quality and innovation—contributions that have helped the company become a recognized leader in the steel casting industry.

Automation in investment casting is often seen as the domain of large-scale foundries, with a common perception that it requires major capital investment, significant floor space, and rigid shop-floor layouts. But what if there were a way to bring the benefits of robotic automation to foundries of any size?

The Eagle Group realized early on the value of 3D scanning for manufacturing. Eagle CNC, Eagle Precision and Eagle Alloy all utilize 3D scanning systems that optimize our capabilities not just for inspection, but also for reverse engineering and prototyping. For us, scanning is an integral part of the casting process.

That’s why Eagle Alloy has upgraded its Keyence scanner several times to stay ahead of the curve. Our latest model, the WM-6000, helps our shell-mold foundry deliver even more precise, reliable castings for our customers.

How Eagle CNC’s internship program benefits students, the company and the industry as a whole

In the hands-on world of manufacturing, textbooks alone can't provide the full picture—real-world experience is essential for developing expertise and encouraging innovation. For both students and manufacturing companies hoping to secure talented employees in the future, internships bridge the gap between classroom theory and hands-on application, pushing limits and enabling creative problem-solving. By integrating internships into their operations, manufacturing companies foster a continuous cycle of learning, adaptation and improvement that drives innovation forward in the industry. Eagle CNC is committed to shaping the next generation of manufacturing professionals by providing practical experience and fostering essential, real-world skills through its internship program.

After a casting solidifies in the mold, the part undergoes a number of post processes to prepare it for delivery. One of the most commonly used post processes is blasting, an intensive cleaning process that removes debris and excess material from castings. At the Eagle Group, blasting plays a pivotal role in prepping casting surfaces for delivery or for further processing. Our latest investment in state-of-the-art stainless-steel grit and an optimized media blasting process is paying dividends for our customers and our employees by providing cleaner parts, less oxidation, and a safer workplace.

But getting to this point has been a years-long journey. Here's how we got here.

Continuous improvement is an ongoing effort to make incremental changes in a company’s processes that improve efficiency and quality. While the concept is fairly simple, many businesses find it challenging to sustain continuous improvement over the long term.

Continuous improvement is one facet of Lean Manufacturing, which is a set of tools used to maximize output and minimize waste. The meaning of ‘minimizing waste’ in manufacturing is a far-reaching term. Some examples include:

• Unused material reclamation and recycling
• Cutting down on energy and transportation costs
• Reducing wait times
• Minimizing product defects and returns

Metal fatigue is the cracking and eventual failure of a metal workpiece under the stress of perpetual loading, a type of continual loading known in the industry as cyclic loading. Fatigue resistance in metal parts is the other side of the coin: it represents a part’s ability to avoid cracking and failure under cyclic loading. Not surprisingly, scientists and manufacturers alike have honed the processes necessary to produce components that resist failure from fatigue as efficiently as possible. Manufacturing parts with the aim of resisting failure from perpetual loading is vital for a part’s longevity in service, and for ensuring that our customers are receiving parts that meet a minimum of expected performance life.
