Graphicast recently put a large sample of machined castings through an x-ray testing procedure. A third party laboratory measured the castings against the same standards used for critical components in jet engines and other aircraft applications. The results? A clean bill of health! Take a look at the x-rays yourself. These results clearly show that the Graphicast LTA graphite mold casting process produces extremely dense, low porosity castings. Although these casting aren’t going into a jet engine, they could.
