Automatic Precision Stamping Press

A simple traction system pulls the chain only when the stamping blocks are open, preventing uncontrolled stretching and maintaining perfect tension during operation.
The toggle-based hammering mechanism provides full, controlled power at every stroke while minimising internal stress, reducing wear, and maintaining accuracy throughout the machine’s lifetime.
Tool changeover is quick and secure thanks to the rapid blocking system.
This compact and silent press includes a pneumatic clutch and brake system, along with forced lubrication to ensure smooth, continuous operation.
