Profile: SIC Marking USA specializes in providing automated identification and marking solutions. SIC Marking® laser marking solutions are based on fiber laser technology. Lasers can produce marks on numerous materials, notably the hardest ones, with no mechanical contact. Laser marks are precise and permanent. Our robust scribers noiselessly produce deep grooves to form continuous lines. Dot peen marking is made from a succession of dots. This type of marking does not require consumables. Our portable, hand-held marking guns are suited for marking heavy materials, or parts too large to be handled easily. These machines can mark parts with surface hardness of up to 62 Hrc.
