As discussed, Teflon absorbs 10.6 µm laser energy readily and ablates cleanly. Due to its high melt temperature, and inherent purity, Teflon ablates cleanly from the bulk material. PTFE, poly(tetrafluoroethylene), poly(difluoromethylene), poly(tetrafluoroethene), poly(1,1,2,2-tetrafluoroethylene). They developed a special version of their popular M-100LFG Series UV Laser Wire Markers that can be fully integrated with Schleuniger’s line of cut and strip machines. The carbon black pigment used to create black Teflon absorbs fiber laser energy very well. We have CO2 laser series stripping machine for Stripping of non-metallic materials such as wire jacket and insulation, including vinyl chloride, glass fiber, polyester, polyester film, fluoride, nylon, polyethylene, tantalum resin, aluminum foil, Teflon and others Hardness or high-temperature insulation materials, etc. Laser Marking Ra 8 Surface 304SS Plate. In the case of Teflon, virtually no HAZ is created because Teflon possesses a high melting temperature; this means adjacent surfaces can withstand conducted heat without melting or boiling. Fiber lasers operating at 1.06 µm are also ineffective at creating contrast on pure white Teflon. When Teflon absorbs laser energy, it rapidly converts optical energy into molecular vibrations (heat). Ident Marking can effectively mark white or colored insulation including XLETFE, PTFE, FEP, ETFE or similar jackets. Gaseous phase effluent is also present and includes carbonyl fluoride, fluoroform, hexafluoropropylene, and tetrafluoropropylene. It is most abundant in sheet, tube, and rod shapes. When properly controlled, the polymer will begin to boil, creating more surface area. A laser system may remove material completely from the top to the bottom surface (commonly be referred to as ". PTFE, poly(tetrafluoroethylene), poly(difluoromethylene), poly(tetrafluoroethene), poly(1,1,2,2-tetrafluoroethylene), Laser cut 0.25" thick diamond shape from white Teflon, Serial number, font size 24 applied to black Tefon using laser depth marking, Serial number, font size 24, marked on the surface of black Tefon.

All other company and product names are trademarks or registered trademarks of their respective companies. Material directly in the laser path is cleanly ablated away into vapor and a fine Teflon powder. Using ink-based methods to identify Teflon parts always fails because the ink simply won't stick to the surface. Laser material interactions almost always create gaseous effluent and/or particulate. LASELEC’s Laser wire markers have no problem marking on Teflon wires, as they cannot smear or run over the wire. Alternatively, the effluent can be treated with a filtration system first and then routed to an exterior environment. The example shows a serial number marked on the surface of black Teflon. DLMP technology creates permanent engravings without the hassle of handling messy inks. Fiber and CO2 lasersare best for marking and engraving on most synthetic polymers and organics such as wood, pape… Marking. MLT laser markings meet these requirements without the need of ink and acid etching chemicals disposal. Multiple processes can be applied to Teflon without having to move or re-fixture the material. It is a synthetic fluoropolymer most noted for its anti-stick, water-repelling, chemical resistant and temperature resistant properties. Material ablation is a physical process that removes material. Carbonization is a thermo-chemical laser marking process that can produce high contrast marks on synthetic polymers. The additional surfaces refract, resulting in a high contrast, off-white mark on black Teflon. Surface Finishing Brunk provides a variety of surface finishes including deburring, bead blasting, plating, passivating, laser marking, heat-treating, teflon coating, powder coating, electro-polishing, selective plating and continuous plating of preformed plates. What types of laser sources are used for laser carbonization? © 2020 Universal Laser Systems, Inc. All rights reserved. Due to its exceptional properties, Teflon® is suited for the most demanding environments in commercial, industrial, and aerospace applications.The carbon-fluorine bond that dominates the molecular structure makes Teflon resistant to the most aggressive chemicals, including hydrofluoric acid. 2 Fiber Laser Industrial Etching & Marking e-Book Introduction The fiber laser has been a great tool for our customers because it meets an entirely new set of needs The ability to etch and mark so many types of industrial products means that you have the challenging task of determining how to The example image demonstrates how processes can be combined to cut Teflon from sheet stock, engrave a diamond shape into the material, and surface mark a serial number. Some ten years ago 308nm excimer lasers were used for marking Teflon aircraft wire. There is a method, however, of producing contrast on black Teflon. Then Accumet can be an economical solution for a fast-turn quality product.. The most common colors are white and black. Delrin, Teflon, PEEK, and ABS are examples of medical plastics that are commonly marked by the laser plastics engraving process. Multiple processes can be applied to Teflon without having to move or re-fixture the material. However, not all polymers are markable and dark color materials are also not apt for usage with UV laser marking. Certain types of material should not be engraved or laser with a laser because of their chemical make-up. Many industry and government marking standards have strict guidelines about for marking requirements like MIL-STD-130M for the military and SEMI M12/M13 for semiconductors. Furthermore, higher complexity in machine design implies a higher upfront cost. When properly controlled, the polymer will begin to boil, creating more surface area. Due to its exceptional properties, Teflon is suited for the most demanding environments in commercial, industrial, and aerospace applications. Teflon is an excellent absorber of CO2 laser energy (wavelength=10.6 µm). It is most abundant in sheet, tube, and rod shapes. The example shows a serial number marked on the surface of black Teflon. 99. Our "Advanced" laser training class covers this. ORTUR Laser Master 2, Laser Engraver CNC, Laser Engraving Cutting Machine, DIY Laser Marking for Metal with 32-bit Motherboard LaserGRBL(LightBurn), 400x430mm Large Engraving Area (20w) 4.2 out of 5 stars 313. We offer a wide range of custom finishes to… Gaseous phase effluent is also present and includes carbonyl fluoride, fluoroform, hexafluoropropylene, and tetrafluoropropylene. Laser carbonization can also be performed on organic carbon containing materials such as paper, cardboard and wood. The primary decomposition mechanism of Teflon® when using laser ablation processes is scission; smaller particles of Teflon are ablated from the material and deposited in a fine white powder. © 2020 Universal Laser Systems, Inc. All rights reserved. With sufficient heat, Teflon undergoes “scission”, where the bonds between repeating units are broken cleanly, without significant degradation of the base unit. Magnetic Sheet Cuts beautifully NON-CHLORINE-containing rubber Fine for cutting. Major Laser Technologies UV Laser Marking. ... Teflon (PTFE) thin Cuts OK in thin sheets. Why is laser wire marking better than other methods. The laser must also be run at a low-speed, high-power configuration to allow the marking agent to adequately bond with the metal. Most laser markers will simply overpower a plastic surface with heat, which can lead to burning, bubbling, scorching, melting or otherwise damaging the material.
