There are systems with an internal impact mechanism. The strike is not produced by the power of contact when the head is descending onto the support but from the accumulation of energy in a compression phase of the striking tool, then from the rapid release of this energy.

In order to impact, the machines are equipped with:

  • Character holders and commutable characters
  • Manual or automatic dialers
  • Engraved punches
Matérials Applications fields
  • Mechanical Industry
  • Automotive Industry
  • Plastics Industry
  • Locksmithery
  • Permanent embossed marking
  • Quality standards of marking even on the hardest steels
  • Low- maintenance
  • No training required
  • Large possibility of marking: text, logos, numbers…
  • Perfect repetitiveness of the marking power
  • Fast change of marking references
  • Efficiency, simple, robust and very fast
