Program Addressing Graphite Manufacturing Consistency

Anyone citrus fan who also happens to work in graphite engineering knows there is more than one way to peel an orange, just as there is more than one way to reverse-engineer or fabricate a graphite component for a customer. These days, all CNC milling machines use software and programming to machine the custom shapes associated with custom parts. Our CAD Department uses CAD Models (Solid Models) to extract the needed features of a custom part in order to create programs necessary to machine that part. One would assume that such a system would guarantee consistency each time we run...

Continuous Casting in Graphite Materials

When people ask us at Semco what is so special about graphite, we usually describe the amazing versatility of graphite materials. The applications that are optimized by using graphite materials are only limited by the imaginations of engineers. One such application, of both ISO-molded and extruded graphite, is a casting method called continuous casting. What Is Continuous Casting?This casting method is used in high volume production of metals with a constant cross-section. The method uses an open ended graphite die which is surrounded by a copper jacket through which molten metal is poured. The graphite mold is typically water cooled....

Flexural Strength vs Compressive Strength in Graphite

Flexural Strength vs Compressive StrengthIt is an oddity of the graphite business, and in many other endeavors in life, that the more you know about something, the more you realize you still don’t know. At Semco Carbon, we do know there are many elements in graphite component design. We’ll go ahead and claim to know most of them (hey, decades in the same business can teach you a lot). But what we recognize is that when a client brings to us a problem with a graphite component that we machined, we may not immediately know what the problem is nor...
