The truth is, graphite manufacturing has never been particularly "green." Synthetic graphite production consumes enormous amounts of energy, and the recycling of graphite has historically lagged behind other materials. As we’ve written about in a previous blog, we were called in to extract large graphite electrodes that had been disposed of in an Iowa cornfield. Yet we're seeing real changes in how graphite gets made and how it's being recovered and reused....

How Graphite Solutions Help Reduce Industrial Carbon Footprints

It's a funny thought, right, carbon graphite helping to reduce industrial carbon footprint, lower emissions, and combat climate change. To us at Semco, well acquainted as we are with graphite's stellar thermal management, durability, and key role in green technologies, the idea that carbon graphite plays a role in reducing emissions and industrial carbon footprint is not surprising at all. In fact, for years we've explored this topic in piecemeal ways in this blog (see this blog that includes how carbon graphite plays a part in hydrogen fuel cells, for instance). Here, we will take a look at the overall...

5 Ways Custom Graphite Machining Enhances Industrial Productivity

5 Ways Custom Graphite Machining Enhances Industrial ProductivityThe manufacturing environment is and has always been competitive. As a manufacturing company ourselves, we know at Semco that every advantage matters. Companies constantly seek ways to streamline operations, reduce costs, and improve output quality. For example, we have written here about Semco's pursuit and achievement of ISO-9001 certification, a process which led us to find new strengths and efficiencies in our graphite machining operation. We have also written extensively about our use of CNC machining. For many manufacturers, custom graphite machining offers multiple pathways to enhanced productivity that many manufacturers overlook.
