The PDS unit offers Optima's toggle system in a compact and versatile form. Clamp force is generated mechanically after being hydraulically activated. In the clamped position the unit is mechanically locked and fail-safe.
The unit also incorporates Optima's unique "Activator" system. This system allows the clamp to monitor clamping force, tie-rod failures, die or platten deformations, as well as any changes along the clamp line. Any irregularities will result in an immediate press shutdown.
Due to its design and the unique 180° swing radius of the tie-rod, the unit completely disappears from the platten surface. This allows dies or bolsters to be brought in from any direction.
