Continuous Casting in Graphite Materials

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. 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. This cooling method...

Flexural vs Compressive Strength in Graphite

Flexural vs Compressive Strength in Graphite

It 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, 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 how to fix it. In fact, we’ve...

The Tech Side of Graphite Fabrication

The Tech Side of Graphite Fabrication

Your business is designing a manufacturing set-up. One of the constituent parts will be exposed to various chemicals and high heat. Graphite is considered for this part because it is chemically inert and stands up to extreme temperatures without degrading. Engineers make a mock-up of this manufacturing set-up and they Zoom call us at Semco. Customer: “Hi, we finished the mock-up of the apparatus and it looks like we’ll need a graphite mold about 7 or 8 inches long that looks kinda like this (holds up napkin drawing of future graphite component). Semco engineer: “That’s a nice drawing. Could you...
