Sinker EDM Parts
Die sinking EDM spare parts consist of an electrode and the workpiece is submerged in an insulating liquid. The electrode and the workpiece of EDM machine spare parts are connected to a power supply in which the electrode is made according to the required shape. The machine uses the shape of the electrode to erode the inverse shape in the workpiece.

DESCRIPTION OF EDM SINKING
How EDM Die Sinking Works
A “bridge” is created between the part and the electrode.

A spark is created.

The spark creates heat.

Plasma is created around the spark that melts the material.

The spark is turned off and the area implodes on itself, removing material.

The dielectric fluid flushes the zone to start again.

ADVANTAGES OF EDM SINKING
Improving Productivity
Having a productive die-sink EDM process is relatively straightforward: Create the correct work environment, use up-to-date technology of making mold spare parts, and eliminate rework.

Generator Technology
The EDM’s generator technology creates sparks while controlling electrode wear and optimizing cutting speeds. On certain die-sinking EDM aluminum parts, the technology manages the electrical current between the fronts and sides of electrodes and controls its delivery to minimize lateral sparking that disrupts effective machining of areas such as the sides of mould cavities. The system allows the electrode to have maximum power in the front of the cavity without destroying or creating oversize gaps on the cavity side walls.
