A punch is a similar to a “stamp” and it is used to mark metals such as steel, bronze and aluminum mechanically, without the use of acids or other chemicals. The sharpness of the brand and the quantity of the branded material depend on the quality of the punch and the complexity of the brand itself. Thanks to the laser marking systems Libe can perform machining with the outmost accuracy of profiles and geometries, placing itself as a valid alternative to the classic EDM.
