Electropolishing is an electrochemical process similar to, but the reverse of, electroplating. The electropolishing process smoothes and streamlines the microscopic surface of a metal object. As a result, the surface of the metal is microscopically featureless, with not even the smallest speck of a torn surface remaining.

Before researching the topic, I knew about rhabdomyolysis from a clinical standpoint. I had experienced caring for patients in the ICU (most of which were crush patients) who developed “rhabdo”, but was unaware of its prevalence in the non-clinical setting. Rhabdomyolysis comes from the Latin roots rhabdo meaning striated, myo refers to muscle, and lysis which means to breakdown or rupture. Put together, rhabdomyolysis is a dissolution of skeletal muscle producing a clinical syndrome that causes extravasation of toxic intracellular contents from the myocytes into the circulatory system.1 Rhabdomyolysis comes in several forms. Nonexertional rhabdomyolysis occurs after traumatic events such crush injuries, while exertional rhabdomyolysis occurs after high volumes of intense physical activity.2 Exertional rhabdomyolysis develops more frequently in athletes under heat stress and in the presence of dehydration.  Read more.

Investment Castings

Precision Investment Castings

The Investment Casting process begins with producing a heat disposable pattern. This is accomplished by injecting wax or plastic into a metal die. A pattern must be molded for every casting.

These patterns are assembled into a cluster (or tree) and are then coated with various liquid ceramic refractories to form a ceramic shell. The wax or plastic is then melted out of the ceramic shell.

Any number of different alloys can be cast into the ceramic mold. After cooling, the ceramic shell is removed and the castings are cleaned.

The investment casting process maintains typical dimensional accuracy of +/-.005″ per inch, with a surface finish of 125 RMS or better.
