Technology Presentation


  • PUMA Hammer - Punching Machine
    PUMA Hammer is a heavy-duty<br />device suitable for use in extremely<br />harsh C.C. environment for<br />marking billets, blooms, slabs at<br />very high temperature...

  • The PUMA HAMMER uses a very hard, wedge-shaped single chisel, moving along X-Y directions in the work area; segments are sequentially indented, moving and rotating the chisel at high speed; this assures a good penetration and, differently from punching a character in a single shot, assures to have always the whole character even if the surface is uneven. Special font design in order to print unmistakable characters. Special features are available for marking stainless steel and in general, all special steels that, when flame cut with the addition of iron powder, show thick scale.

    PUMA Hammer is basically composed
    by :
    • the punching head
    • the pneumatic cabinet
    • the control unit

    PUMA Speedy is the system developed by GP for punching metal products out of hot and cold rolling mills (like plates, pipes, beams, etc.)....

  • The main feature of the system is the capability to punch a large number of characters in a very short time; this is obtained by moving one or more multi-pin packages (with configurable pins number) in X-Y directions, during the movement each pin marks simultaneously a portion of the message. Characters are defined by a matrix of dots indented in the metal surface, penetration force is adjustable. 

    PUMA Speedy is basically composed by :
    • the punching head
    • the pneumatic cabinet
    • the control unit
