ISEM-7 Carbon Graphite Toyo Toyo ISEM-7 Carbon Graphite ISEM-7 graphite material ISEM-7 graphite EDM uses density compared with traditional copper electrode, Toyo Tanso of EDM graphite material has the following advantages: 1. lower material costs: the same volume of only 50% of the price of copper graphite electrodes; 2, faster processing speed: the machining speed is 2 to 3 times the copper electrode and the machining burrs; discharge machining speed than copper Electrode 34% to 200% faster; 3, a smaller loss: oil breakdown spark carbide coating, the electrode wear compensation; 4, lighter weight: copper graphite density of only 1/5, and therefore more suitable for large electrode discharge; 5, easily deformed material: Compared with copper electrodes, graphite melting point of 3650 degrees Celsius, will not deform under high temperature, more suitable for processing bone bits electrode; Dongguan Hua Mai service first, quality first 6 machines No post-processing glitches and easy to polish, save and improve secondary processes; 7, adhesion: Available adhesive bond breakage of graphite, to save time and material costs. It is because of these advantages, as well as cost-effective carbon products Toyo Toyo carbon graphite EDM is being more and more Chinese enterprises are recognized and accepted by the mold, and eventually became a partner Toyo Tanso. Dongguan Hua Mai service first, quality first large, low-loss fine graphite: ISEM-7 ISEM-7: Physical characteristics Grade Bulk Density Shore Hardness Specific Resistivity Flexural Strength Average Grain Size ISEM-7 1.77g/cm3 62 12.5μΩ m 51.0? MPa 8μm TOYOTANSO of ISEM-7 material is a fine large isotropic graphite material with a very high price, while both higher metal removal rate and discharge rate for Fuji's large cavity electrode material selection . Scope: Suitable for die casting, forging die; injection mold generally rough and finish; such as automotive mold, mold and other general home appliances.
