graphite mold for electric discharge machining

US4808354A

A method for fabricating electrical discharge machining electrodes includes forming a thin electrode shell by compression molding a mixture of carbon particles and an organic binder. The electrode shell is then thermally processed to graphitize the organic binder and carbon producing an electrode with the structural integrity needed so as to be useful in electrical discharge machining.

Moldmaking and Graphite Electrodes

2016/3/23It seemed, for a certain period, that graphite electrodes were becoming obsolete. This is mainly due to the advancements in the machining of hardened steel. However, the widespread application of electric discharge machining or EDM has increased the demand

Fast track that let no trace Graphite machining has never been so attractive—and challenging. While graphite electrodes boost die-sinking electrical discharge machining's (EDM's) productivity and reduces costs, the graphite-based glass mold market is quickly growing, with new requirements in terms of surface finish, precision and machining speed.

What is Electrical Discharge Machining (EDM)?

2018/5/17Die-sink EDM removes material from the workpiece—the mold in this case—with a graphite electrode, dielectric fluid, and electric current to create a spark discharge. The spark discharge erodes the workpiece to form the final geometry.

High speed electrical discharge machining by redressing

In this embodiment, the graphite electrode is both formed and redressed by ultrasonic machining, and the graphite electrode is employed in orbital electrical discharge machining of metal workpieces. These operations are performed in cycles as required in an integral machining operation on a single machine tool at high production rates.

The Injection Mold Making Resource

The health and welfare of toolmakers that use EDM graphite to make electrodes for use in the electrical discharge machining process should be a high priority for management. In addition to the health issues for the workers, the very expensive machinery, such as the EDM machines and milling machines, must be protected from the damaging effects of graphite dust.
