The function of EDM processing in injection mold manufacturing
The manufacturing of injection molds is an industrial work that integrates multiple functional processes. Through the support of different processes, the expected mold level can be achieved. There are plenty of processes in molding manufacturing, such as electroplating, EDM milling, etc. As the most important part of mold making, EDM directly controls the precision of the mold dimensions.
The full name of the EDM process is electrical discharge machining. The basic working principle of EDM is to use electrode wire as an electrode to cut and shape the metal parts into the desired structure. EDM is mainly used for processing complex shapes and high precision products, it has the advantages of high accuracy, short production cycle, and low cost, it has become an imperative part of mold processing.
Mostly. EDM needs to work with EDM oil, the EDM oil is used as a spot medium, and can be worked as a cooling method. When the EDM machine is working, the instantaneous temperature can be as high as 10000 degrees Celsius, and the surrounding pressure will also vary greatly, so EDM oil can provide a stable and safe environment for the whole processing with high temperature and pressure.
