Teflon: Not Just for Non-Stick Cookware

Graphite 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 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. Between the high thermal conductivity and electrical conductivity of graphite to the chemical resistance and low friction of both materials, Teflon-coated graphite makes a...

International Organization for Standardization 9001 Certification

Semco Carbon is proud to be an ISO 9001-2015 certified company. The decision 4 years ago to prepare, apply, and become certified was driven by our belief that we were already operating at a high standard that the certification would indeed confirm. We also knew that working towards and achieving this certification would contribute to the success of our company in many ways, from strengthening supplier relationships to improving the morale at our manufacturing facility in Lorain, OH. It was no small decision to apply for this certification, and it took hard work and collaboration by and across all departments...

Computer Aided Design, or CAD

Computer-aided design, more commonly known as CAD, is the use of computers in the design process across a wide range of industries. CAD software is primarily used to create highly accurate models, but CAD covers all steps in the design process, from creation and modification to analysis and design. In our industry, CAD software is notably used to create precise drawings and models of objects and structures. CAD was developed as a more accurate, affordable way for designers, engineers, and manufacturers to design, visualize, and test models while minimizing the chance of mistakes. As CAD allows for easy modification, documentation,...

Graphite Heating Elements in Vacuum Furnaces

In our graphite machine shop, we have the three things necessary to produce graphite heating elements of any type or size: a variety of graphite blocks, machines optimized for machining graphite, and skilled and experienced graphite machinists. If your manufacturing facility produces sintered metals or brazes copper, or in any way employs high-temperature vacuum furnaces in your manufacturing process, you likely rely on graphite heating elements. There are many reasons that graphite is the preferred material for heating elements, several of which we discuss below. Why Graphite Heating Elements? Graphite is a desirable material in various thermal applications due to...

Impervious Graphite Grades in Process Equipment

Most graphite applications are designed with a particular graphite grade in mind. Impervious graphite grades, where the original material is altered to eliminate porosity, are especially in demand for some common graphite applications. Graphite process equipment, especially heat exchangers, are increasingly being used in chemical processing, as well as pharmaceutical and other process applications requiring high corrosion resistance. Graphite Applications in Heat Exchangers Any graphite grade has great thermal conductivity that makes it suitable for the construction of heat exchangers and other process equipment. These systems transfer heat between a substance and a fluid, many of which are corrosive. Not...
