15-year precision mould making

    The EDM machining of mold parts is a kind of hot processing method. It can be converted into heat energy by using electric energy, which makes the work piece melt quickly. The phenomenon of arc discharge is generated in the gap between the electrode and the workpiece, and then the thermal effect on the workpiece. At the same time, the working fluid is gasification and blasting under the discharge pressure and heat, and blasting impact force washes away the melting part of the work piece. So repeatedly, it can be processed into the shape we want. It can be known that the discharge machining has nothing to do with the hardness of the workpiece, as long as the mold components material can be conductive can be processed.
    Ceramic, glass and other non conductor materials, generally can not be use the discharge to process. However, recent studies in recent years found that the use of a special way, non conductor materials can also be used for electrodischarge machining. Therefore, the discharge machining is the first to make the electrode, the shape of the electrode is consistent with the processing of the cavity.
