Boring may not sound like a very exciting topic, but don't let names deceive you: boring is one of the most widely used techniques in machining, and one of the most reliable ways to finish holes.
Boring is the process of enlarging and finishing pre-existing holes. The holes might have been cast, drilled or otherwise formed to a rough state, but boring is often the best technique to provide the accuracy and repeatability expected of CNC machined parts.
Forget about the Rose Bowl–this year's college competition to watch is coming up in February!
The AFS Wisconsin Regional Invitational Casting Competition will host casting teams from colleges and universities around the Midwest. Taking place during the AFS Wisconsin Regional Expo and Conference, the event invites student teams to present cast products they've created using school casting facilities. All projects in competition were completed by members of AFS student chapters.
Greensand casting is a time-tested and highly versatile metalcasting process. Different foundries use different methods and materials, but greensand casting always involves creating molds by compacting moist, organically bonded sand around patterns. Whereas shell molding uses heat-bonded sand and no-bake casting uses chemically bonded sand to form molds, greensand casting is unique in that sand is bonded through naturally occurring compounds–in most cases, the bonding agent is clay.
At Eagle Aluminum Cast Products, our two principle casting methods are greensand and permanent molding. The greensand process is very customizable and capable of manufacturing nearly any type of cast product. Here, we'll explore the processes, casting characteristics, benefits and challenges of the greensand casting process.
At Eagle Alloy, we recently expanded our capabilities by investing in three new Inductotherm induction melting furnaces. Since opening in 1979, we’ve always used induction for melting because of its efficiency and flexibility in comparison to other heating methods. These new furnaces allow us to increase our melting capacity both now and in the future.
It's easy to agree with Inductotherm when they say that "watching a piece of metal in a coil turn cherry red in a matter of seconds can be surprising to those unfamiliar with induction heating." The process of induction heating is as fascinating as it is useful. Here, we explore the origins of induction heating and its applications in metalcasting.
Cem-Tec, a manufacturer of steel light poles in business since 1974, approached Eagle Alloy, Inc. with an emergency order. Due to an unforeseen supply-chain issue, they needed to find a new foundry to manufacture one of their popular products. With orders in and customers waiting, the clock was already ticking.
The following case study illustrates the steps Eagle Alloy followed to transfer casting of the product to our facility and to ensure that Cem-Tec had high-quality products ready for their customers as soon as possible.

The Michigan Manufacturers Association (MMA) is proud to announce Eagle Alloy of Muskegon has been selected as the 2018 recipient of the John G. Thodis Michigan Manufacturer of the Year Award. A prestigious honor since 1981, the award is named after MMA’s longest-serving president and honors the important, positive and tangible contributions individual manufacturers make to their employees, customers and communities. The Eagle Alloy team received the award during the 2018 MFG Excellence Awards on November 8 at the Kellogg Center in East Lansing.
Drilling is one of the most common techniques used in manufacturing to create holes. In contrast to other hole-making methods like boring, reaming and tapping, drilling is most often used to create holes in unbroken surfaces. In precision CNC machining, drilling can range in scope from simple, rough hole drilling to complex, multi-feature hole drilling.
Eagle Alloy was lively and bustling on Thursday, October 4th. That's no surprise: our Muskegon, MI campus is regularly buzzing through three shifts a day, five days a week. But this particular day brought in a larger crowd than usual: in celebration of Manufacturing Day 2018 we opened our campus to local schools and community representatives for a demonstration of modern metalcasting.
The goal of Manufacturing Day is to inspire the next generation of manufacturers, and we wanted to support that goal any way we could. By inviting students to witness our work firsthand, we aimed to provide an introduction to modern metalcasting and manufacturing. After nearly 40 years in business, we understand the importance of letting young people know about the exciting potential of metalcasting careers.
During the Eagle Group's product design process, sample runs of new cast products are subject to some of the most rigorous inspection processes available. The inspection methods we use prove to our customers that their parts will conform to specified tolerances and be free of defects. From magnetic particle inspection to laser scanning, we make sure that every new product passes a gamut of tests before it ships to the customer.
The Eagle Group regularly makes use of robust inspection technology to discover and diagnose any flaws or defects present in metal parts. In some cases, we use these methods to reverse engineer an existing part brought to us with defects. In other cases, we've pinpointed flaws in the initial design that lead to downstream manufacturing challenges.
The rise of CAD/CAM software largely defines the current era of manufacturing. While blueprints and dimensional charts are still widely used as reference guides, modern manufacturers rely on software to design prototypes and simulate casting processes. One of the first steps in the cast part development process is to create a 3D model. From there, engineers can improve the part shape, simulate a variety of casting processes and materials, and troubleshoot difficult manufacturing scenarios.
When done right, CAD/CAM software enables foundries to solve all the problems of casting in the virtual world, before pouring any metal. The results are cost savings for the customer, time savings for everyone, and reduction of overall waste.
