@1.Tips here on which functionshould I choose ? If you need a colorful marking on ss,sometimes needs deep engraving, you could select the SMARTECH JPT If you only needs deep engraving on metal, no need colorful marking,then you could select JPT LP series. If you need to process on curve materials, you need the 3D laser. If you no have special requirements on the processing,just need to write the logos/text/images marking,then laser with raycus is ok,please contact us for Smart-F series quotation list. @2.Applications: 1.Aluminium sheet stripped surface: No deformation, fine marking, color marking. 2.Metal depth marking. 3.Stainless steel color marking: marking different colors by setting the parameters. 4.PCB, ABS, Plastic without yellow color. 5.Light transmission paint keyboard: easy to make it previous to light. 6. Electronic, semiconductor components, ITO precision machining: the pulse can be adjusted to get best facula, and make the power balance 7.color marking and black marking on stainless steel. 8.Black marking and deep marking on nonferrous metal,like copper,alumina,aluminum. 9. Excellent marking effect on plastic or other sensitive material 10. Semi-conductor&electronics industry applications 11.Customade converyor belt for pen marking with much more high efficient work. Metal materials:stainless steel,aluminium,copper,silver, gold, carbon steel etc Non-metal materials :plastic,pvc,rubber,glass,stone,wood,feather,jewelry etc
