IME-Series - dielectric for die-sinking EDM

Dielectrics for spark erosion!

oelheld dielectrics IME have been tested in extensive experiments , have proven themselves in practice for decades and are recommended by leading manufacturers of spark erosion plants.

oelheld dielectrics IME posses greatest disruptive strength, they are clear fluids and are almost odourless. During erosive process they do not change their colour. They have the same purity as pharmaceutical white oil and are free of aromatic compounds.

Whether in rough cut operations or in fine work – the dielectric must meet the specific requirements of each particular case of application.

The high-performance dielectrics for use in electrical discharge machining are produced on a synthetic base and have additives with aging inhibitors.

Dielectric IME 63
Dielectric IME 63 is extremely thin-bodied and has a particularly low surface tension. It is especially suitable for very fine work where the least possible overcut is required (e.g. micro drilling of spinnerets and the manufacturing of microelectronic parts).

Dielectric IME 82
Dielectric IME 82 combines high metal removal with electrode wear, which makes it particularly suitable for general use in manufacturing tools and moulds. Even rough cut operations using an electric current of up to 1000 amps can be carried out with this dielectric.

Dielectric IME 110
Dielectric IME 110 is mostly used if a flashpoint of 100 °C is required for safety reasons, while simultaneously much finishing still has to be done. This is a universal product that can be used from rough to fine finishing.  Best results are achieved by using graphite electrodes.

Dielectric IME 126
Dielectric IME 126 is characterised by very high metal removal and is particularly suited for rough cut operations, such as the manufacture of forging dies. It can only be used for finishing, if the best possible flushing conditions are ensured.
