The Installation of Our New 2000 lb Gorbel Overhead Crane

Semco is excited to share another significant update from our graphite machining facility in Lorain, OH: we recently installed a new 2000 lb Gorbel Overhead Crane. This state-of-the-art crane is a game changer for our operations, particularly in our lathe department. Our Haas lathes are state-of-the-art, but the ways we were moving graphite blocks and tools around the department was not. That changed with the installation of the Gorbel Overhead Crane, which spans across the shop floor, creating a safer work environment for our team and enhancing efficiency in loading and unloading parts and tools. The Overhead Crane’s Safety Impact...

Graphite and Oxidation

A recurring issue we hear about from people using graphite components is graphite oxidation. This term describes unwanted redox reactions where oxidizing agents modify graphite properties negatively. Hence, especially at high temperatures, steps need to be taken to eliminate oxygen presence so that oxidation and deterioration of graphite components is avoided. Semco strives to educate our clients who order custom graphite components about the proper environments in which those components should operate. However, new clients will come to us expressing their frustration that graphite components are failing long before they should. One reason to work with the synthetic graphite experts...

Graphite Cement: A High Temperature-Resistant Building Material

Graphite cement typically refers to a material with adhesive and bonding physical properties that contains graphite as one of its primary components. This is not your typical cement, one of the most ubiquitous, and necessary, building materials used by people today. Your typical cement is made of forms of lime, silica, iron, and aluminum. Like manufactured graphite, cement’s formula can be adjusted to suit specific purposes. One of those materials that can be added to cement to give it certain properties is graphite. Graphite is a form of carbon known for its excellent electrical conductivity, lubricating properties, and high temperature...

Teflon: Not Just for Non-Stick Cookware

Teflon History and ApplicationsGraphite is a high temperature-resistant material. It isn’t too surprising then to find that graphite and Teflon have been combined in industrial applications that go beyond just non-stick cookware, like gasket material (and many others). Teflon-coated graphite refers to a material that consists of a layer of Teflon (a brand name owned by The Chemours Company, for polytetrafluoroethylene, or PTFE) applied to the surface of graphite. This combination offers unique properties and applications, primarily due to the characteristics of both materials. Teflon was a revolutionary invention (or "lucky accident" in the eyes of some!) from it's conception. Roy...
