Aluminum alloys are among the most widely used materials in aerospace and robotics due to their combination of light weight, strength, and corrosion resistance. Within the aluminum family, 6061 and 7075 alloys stand out as two of the most popular options. Choosing the right alloy can mean the dif

Custom fixtures play a critical role in precision machining. Whether used for aerospace components, medical devices, or high-tolerance industrial parts, a well-designed and accurately machined fixture directly impacts dimensional stability, repeatability, and production efficiency. Poorly manufac

Manufacturing is gradually shifting away from traditional mass production toward more flexible and customized production models. Many industries today require smaller production runs while handling a wide variety of part designs. This manufacturing approach is commonly known as low-volume, high-m

As modern industries continue to push the limits of miniaturization, the demand for extremely small and highly precise components has increased significantly. Sectors such as medical devices, aerospace systems, robotics, and advanced electronics often require parts that measure only a few millime

Polyamide and nylon are among the most widely used engineering plastics in modern manufacturing. Both materials are valued for their excellent strength, durability, and resistance to wear, making them suitable for a wide range of industrial and consumer applications. However, although these two t

When developing a new product, one of the most important decisions engineers and procurement teams must make is choosing the right manufacturing process. Two of the most common options are CNC machining and injection molding. Each method has its own advantages, but cost is often the deciding fact

Castellated mounting holes, also known as castellations, are plated through holes located at the edges of a printed circuit board that are cut through using a PCB router to form half-plated holes. These castellated holes usually have a half-circular shape, but they can have other shapes, dependin

ESOP is a way to transfer company ownership from one generation to the next—in many cases, this transfer happens when the original owners sell their stake in the company to their own employees. ESOP stands for Employee Stock Ownership Plan, but the acronym hardly conveys the potential of this empo

Eagle CNC’s West Michigan machine shop provides some of the highest-precision machining available, but the meaning of precision in machining is constantly changing. Industries across the board are calling for increasingly complex parts that challenge traditional machining methods. For a manufactur

When time and flexibility are top priorities, rapid prototyping for castings offers manufacturers a fast-track route to producing complex cast parts in small quantities. At the Eagle Group, this advanced approach supports both prototype development and low-volume production, helping customers refi

“We do outreach because we care about the investment in the future.”— Jason Bergman, Eagle Alloy Michigan ranks #4 in the nation for total manufacturing employment (1). Yet the state—and the nation as a whole—faces a looming manufacturing workforce development challenge. According to a Skills Gap

Maintaining rare or antique equipment often calls for reverse-engineered parts.  Often, the original manufacturer no longer exists—and if they do, there’s a good chance their processes have undergone such drastic changes that they’re no longer capable of producing the part. CAD files are never ava

High conductivity copper castings are a type of casting used in various industries for their useful electrical conductivity properties. Not only are they an affordable option, but they are also durable, easy to machine, and able to fit any industry’s needs. At Burnsten Von Seelen, we

Circuit is the infrastructure of the electrical world. However, perhaps last time the most people saw a traditional circuit connected by wires or cables was on their physics class. Why is that? The answer is PCB. 1. What is PCB? PCB stands for printed circuit board. It’s the board etched fr

PCB (printed circuit board) is playing a fundamental role in today’s life. It’s the base and the highway of electronic components. As far as this is concerned, the quality of PCB is very critical without doubt. To inspect the quality of PCB, several reliability tests must be done. The follo

Increasing demands are being made to settle the cost of machining, since technical ceramics enter the marketplace with new applications. The general perception in the industry is that machining costs are too high and are probably the major pullback to ceramic engineering. In this post, we a

Computer numerical control (CNC) is the automated control of metalworking tools (drills, boring tools, lathes) that can create complicated parts by means of a computer. Generally, a CNC machine alters a blank piece of material (metal, plastic, wood, or ceramic) to meet precise specification

Since any particular component might require the use of different tools – drills, saws, etc. – modern Metal CNC machines often combine multiple tools into a single “cell”. During installation process, a number of different machines are used with an external controller and human

Die casting is a metal casting process characterized by the use of a mold cavity to apply high pressure to the molten metal. Molds are usually machined from high strength alloys, some of which are similar to injection molding. Most die castings are made from non-ferrous metals, such as zinc

The manufacturing process of carbon fiber is complex and challenging. Process variables such as time, temperature, gas flow, and chemical composition need to be closely monitored during each stage of the production. In this post, we will inform you how to control the whole manufacturing pro
