Explosive power is realized by impact by pneumatic.
Appropriate for applications which short stroke and big force is required.

Marking, riveting, punching, deburring, and all other operations which requires short stroke,
DYNA MARKS performs over 10 times of explosive power as any similar pneumatic cylinder.


Pressing down before impact

The workpiece is held down before impact, so that double marking
can be avoided. Also crimping can be done more perfectly.
Speed of holding stroke is adjustable flexibly by controller.
The fixture can be matched safe and easy since the cylinder head
returns to TDC as soon as the valve is released.
Pneumatic for holding is not wasted by accelerating the impact ram.

Powerful explosive

DYNA MARK is utilizes the energy which is generated in impact
ram as explosive power.
The energy is not wasted by synchronizing acceleration of impact
ram with intake of exhaust.

Impact Press

Principle of impact


  1. Impact ram moves downwards.
  2. The tools is held down firmly onto the workpiece.
  3. Impact ram moves downwards.
    Ram impacts against tool holder by receiving
    effect of compress air.
