Teflon is an excellent absorber of CO2 laser energy (wavelength=10.6 µm). 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). Some ten years ago 308nm excimer lasers were used for marking Teflon aircraft wire. Edge-lit RGB LED Sinage. The carbon black pigment used to create black Teflon absorbs fiber laser energy very well. Laser carbonization can also be performed on organic carbon containing materials such as paper, cardboard and wood. ... Teflon (PTFE) thin Cuts OK in thin sheets. The effects of the laser energy interaction with Teflon are material ablation and material modification. Multiple processes can be applied to Teflon without having to move or re-fixture the material. With certain types of plastics like nylon, Teflon or rubber-based materials, the traditional 1064nm wavelength of a fiber, YAG or YVO4 laser may not absorb at all, resulting in no mark. This energy is converted into heat, which is conducted by the polymer matrix. 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. The additional surfaces refract, resulting in a high contrast, off-white mark on black Teflon. There is a method, however, of producing contrast on black Teflon. Laser type: CO₂, Flexx or Fiber laser : Work area: 610 x 305 up to 1016 x 610 mm : Max. Teflon is usually chemically pure, meaning no plasticizers or fillers are added. Material is removed completely from the top to the bottom surface or partially from the top of the material down to a specified depth. Material ablation is a physical process that removes material. Because different types of lasers react differently with metals, there are some considerations to be made. Gaseous phase effluent is also present and includes carbonyl fluoride, fluoroform, hexafluoropropylene, and tetrafluoropropylene. Laser cutting is the complete removal and separation of material from the top surface to the bottom surface along a designated path. Teflon can be engraved cleanly without discoloration or melting. All signs can be customized with any finish. Laser marking and engraving is a computer-driven, environmentally friendly alternative to silk screening, pad printing, stamping, mechanical engraving, chemical etching, and many other costly, lower quality processes. These devices alter the chemical makeup of the material to provide indelible lettering, numbering, or other notation without affecting the structure or function of the material itself. Tri-Star Technologies is a leader in laser wire marking for military and aerospace applications. Again, this is due to its high melt temperature and purity.

The laser energy can ablate material to cut, engrave, or mark the material, or it can change the surface properties to create a visible mark. MLT laser markings meet these requirements without the need of ink and acid etching chemicals disposal. As discussed, Teflon absorbs 10.6 µm laser energy readily and ablates cleanly. Marking. 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 Teflon (PTFE) thin Cuts OK in thin sheets Carbon fiber mats/weave that has not had epoxy applied Can be cut, very slowly. This energy is converted into heat, which is conducted by the polymer matrix. Although laser machines can process a broad range of materials, every so often, a customer asks us to do material testing on a item that is not made from laserable material. The material properties of Teflon, such as high melting temperature and absence of cross-linking, make it highly compatible with DLMP (Digital Laser Material Processing) technology which utilizes laser energy to modify the shape or appearance of a material. Teflon needs to be cut with CO2 laser to ensure that big amount of energy and temperature is supplied to “brake” material. Heat effects can be minimized by selecting an appropriate laser power for a given thickness of material. Alternatively, the effluent can be treated with a filtration system first and then routed to an exterior environment. Using ink-based methods to identify Teflon parts always fails because the ink simply won't stick to the surface. Black Teflon can be marked with a fiber laser to convey information, such as numbers, text, barcodes, and even photographs. Laser cutting Teflon will produce a fine powder of PTFE particles that can be easily cleaned with a dry cloth. 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. Laser depth marking overcomes a long-standing challenge with Teflon. UV laser wire marking was originally developed in 1987 by Spectrum researchers to meet the needs of the international aerospace industry for a means of safely applying permanent identity codes to non-stick PTFE/Teflon and similar wire insulations, as well as fibre optics. Therefore, laser processing should always be supervised. The effects of the laser energy interaction with Teflon are material ablation and material modification. For these reasons, CO2 lasers are commonly employed for laser ablation of Teflon. © 2020 Universal Laser Systems, Inc. All rights reserved. The capability shown can be extended to nearly any shape, even complex and closely-spaced cuts. Teflon is usually chemically pure, meaning no plasticizers or fillers are added. When the laser energy is used to produce a human- and/or machine-readable identification or information on a material, such as a barcode, date/lot code, serial number or part number, the process is considered laser marking with depth or laser depth marking, although it is essentially engraving into the material. Polytetrafluoroethylene (PTFE) is commonly known by the brand name Teflon®. The most common colors are white and black. As discussed, Teflon absorbs 10.6 µm laser energy readily and ablates cleanly. The material just outside of the laser’s spot or path will conduct some heat, but not enough for complete and thorough ablation. Teflon also exhibits very high dielectric strength combined with a high melting point (327°C) and flexibility at low temperature (as low as -79°C).Teflon is available in many shapes and colors. Teflon is the material that is made into very thin sheets and referred to as “Baker’s Sheet” or PTFE. The carbon black pigment used to create black Teflon absorbs fiber laser energy very well. More versatile and less damaging. Engraving and marking are always done before cutting in a combined process.
