Questions about electrical pulse machining for injection mold opening

During the forming and processing of electrical pulses, the pulse width is often referred to as the pulse width. It is the duration of the voltage pulse that is added to the discharge gap at both ends of the discharge gap between the tool and the workpiece. To prevent arc burns, EDM can only be handled with intermittent pulsed voltage waves. Rough machining can be processed with a large pulse width, and only a smaller pulse width can be processed during processing.

Pulse interval is also called pulse interval or pulse interval. This means the interval between two voltage pulses. If the gap time is too short, it is too late to eliminate ionization and restore insulation. The arc discharge phenomenon is easy to occur, and the workpiece and the workpiece are easy to burn. If the pulse is too long, it is easy to reduce the processing efficiency.

The pulse period of an injection mold usually refers to the time between the start time of the pulse voltage and the next impact voltage. It is equal to the sum of pulse width and pulse interval.

The discharge time is the discharge time from the gap through the medium to the end of the current pulse.

The dwell time is the interval between two adjacent discharges and is called the dwell time. The pulse frequency is the number of voltage pulses generated by the power supply per unit time. The peak current is the peak current (instantaneous) of the pulse current during the gap discharge. It has a great impact on surface roughness and processing efficiency.
