Precision Graphite Machining: Best Practices and Common Challenges

Graphite Machining Takes Knowledge and ExperienceWhen it comes to precision machining of graphite, the difference between a quality component and scrap often comes down to understanding the material's unique characteristics. Graphite isn’t like metal or wood. It provides a great many benefits due to its superior thermal conductivity at high temperatures and heat spreading properties making it ideal for electronic components on circuit boards like heat sinks, while it's cost effectiveness also make it a great option for semiconductor manufacturing or any other processes that require high temperatures and the highest standards, It also presents a specific set of challenges that...

Innovations in Graphite Machining Techniques: What's Coming in 2026?

Over the past two decades, the tech world has conditioned us to expect lightning-fast high speed innovation. Now, every few months brings new AI capabilities, faster processors, and software that can do things we couldn't imagine a year ago. It's easy to assume that every industry moves at this pace. But that's not how innovation works in manufacturing, and it's certainly not how it works in graphite machining. Not that graphite machining doesn’t involve cutting-edge technology. It does. We, of course, incorporate automated systems and CAD/CAM machining into our workflows. But at Semco, we keep before us a picture of...

How Custom Graphite Parts Improve Efficiency in the Steel Industry

Steel production has never had a reputation for being clean or efficient. For over a century, massive blast furnaces consumed enormous amounts of coal and iron ore while belching CO2 into the atmosphere. But the steel industry has been changing, slowly but surely. Electric arc furnaces now dominate steel production in the United States, and the shift toward scrap recycling has reduced both energy consumption and emissions. At Semco, we've watched these changes closely because custom graphite parts play a significant role in making modern steelmaking more efficient. The electrical conductivity and thermal conductivity of graphite, along with its thermal...
