The S2DC is an evolution of the SDC, once the SDC has only one row of screws and is able only to push the internal flexible ring against the die reducing the gap the S2DC has 2 rows of screws and can also pull the ring increasing the gap between die and core.
This system can be very helpful in complex shapes ( for instance automotive parts ) and allow a more precise adjustment of the final thickness.
The S2DC is available as a standalone device without the dynamically deformable 3DX system.
