Plastic mold electric pulse to provide the quality of the following two points.

Plastic Mold Electric Pulse,Instantaneous one-way pulse discharge. Spark discharge must be a kind of pulse in the instantaneous discharge, discharge for some time, need to stop for a period of time and then discharge, the discharge duration of about 10s. As the discharge time is very short, so that the heat generated when the discharge is simply less than conduction and spread to the inside of the material being processed, so that the role of energy confined to a very small range of non-stop processing and discharge, to maintain the spark discharge characteristics of cold The energy of the discharge channel energy conversion is too late to pass to the depth of the electrode or the inside of the material to be processed), which not only ensures the good machining accuracy and the higher quality of the surface, but also makes its intrinsic quality not affected by the pulse electrode. And there must be enough time between the two pulse discharge to avoid the occurrence of a variety of arc, local burns and so on. Otherwise it will be like those who continue to let the arc discharge as the core surface completely destroyed. For this EDM must use a special pulse power.Plastic Mold Electric Pulse is such a key point for the mould making.

If there is an insulating liquid medium injection molding. EDM must be in a certain insulating properties of the liquid medium (ie, working fluid), our electrode processing commonly used working fluid kerosene, spark oil, deionized water and so on. Which requires that the liquid medium must have a high dielectric strength in order to produce a certain pulsed spark discharge. At the same time its liquid medium on the one hand so that the corrosion products can be timely discharge, on the other hand it requires the same time can cool the workpiece, so that the pulse discharge can be carried out smoothly. Only after the discharge of the corrosion products in a timely discharge to the discharge channel, the repetitive pulse discharge to smooth the processing. In the actual production of EDM, the discharge of the etch is mainly through the two ways to complete: on the one hand, the spark discharge and the process of corrosion processing itself has the inherent characteristics of the product will be removed, in addition to corrosion (Such as vaporization of liquid media) can also promote the above process; on the other hand must also be good at using some of the artificial auxiliary process measures, such as the working fluid for the cycle of filtration, the process of processing The use of some red, pumping measures and so on.
