Fully servo-electric drives for net shape compaction of highly precise cutting inserts. The SP 160 Electric was the first high-speed servo-electrical powder press in the world. It stands for highest precision and productivity and is available in various versions.

SP Electric -  The Leading Technology Press in Tungsten Carbide and Special Powder Compaction.

Osterwalder Direct Drive Technology DDT connects the output shaft of the motor directly to the spindle. The low inertia leads to an unmatched dynamic motion control. This drive concept optimises precision, maximizes component lifetime and minimizes maintenance requirements. More output with better quality.

Thanks to the innovative drive concept the system uses only energy when axes are moving respectively when powder is being compacted. The system uses no energy in stand-by mode (compact pick-up and in set-up mode). Osterwalder’s Energy Recuperation System recovers energy back into the circuit during axes deceleration.
