DDC – Dynamic Drive Chain
DDC is a servo-drive concept that allows new and existing presses to take full advantage of servo technology with limited peak power.
DDC uses a servo motor to open and close the press faster, while performing the stamping process with energy from the traditional flywheel. This dramatically reduces the cycle time of the press since the major part of the press cycle is performed at maximum speed. Because the stamping process is still performed by the flywheel, no significant additional power is required from the electrical grid
