Replica accuracy is increased by reducing the working gap which is in turn made possible by the PEM process. This makes it possible to manufacture significantly smaller structures and shapes such as prongs, drilled holes, cavities and inscriptions can be easily produced. Simultaneous production of rough and very fine highly-complex structures is also possible. On account of the complex machining process, the electrodes demand a different approach to the one applied in electrical discharge machining processes. Sufficient purging of the effective gap must be observed when designing and manufacturing the electrode. Additionally, a purging chamber may be required in order to retain the electrolyte in the working gap.
Owing to their specific advantages, PEM-machined workpieces offer a very extensive range of possible applications:
Sensory applications · Punching tool construction · Manufacture of die tables and stamps · Mould and tool construction · Micromechanics · Microsystem technology · Apparatus and plant construction · Chemical and pharmaceutical industry · Medical technology · Clock industry · Electrical industry · Environmental technology · Rapid prototyping · Fuel cells (bipolar panels) · Miniaturisation of components · Cold-forming · New (non-machinable) materials · Production of small structures in metallic materials · Multiplication to serial parts · and many more
