The oldest way of marking wires that’s still used in some applications today is hot stamping. It is most abundant in sheet, tube, and rod shapes. The effects of the laser energy interaction with Teflon are material ablation and material modification. Some materials have a propensity to generate flammable byproducts during laser processing. 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.For more information see our Laser Material Processing Whitepaper. Therefore, laser processing should always be supervised. When Teflon absorbs laser energy, it rapidly converts optical energy into molecular vibrations (heat). 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. The mechanical toughness, electrical, and low-friction properties of Teflon® make it the preferred plastic for a host of applications and different processing techniques. The example shows a serial number marked on the surface of black Teflon. Teflon needs to be cut with CO2 laser to ensure that big amount of energy and temperature is supplied to “brake” material. 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. The carbon black pigment used to create black Teflon absorbs fiber laser energy very well. For engraving on Teflon we use Fiber laser which operates at different frequency. When properly controlled, the polymer will begin to boil, creating more surface area. There is a method, however, of producing contrast on black Teflon. The effects of the laser energy interaction with Teflon are material ablation and material modification. Therefore, laser processing should always be supervised. UV laser marking provides a highly legible mark with easy customizable font characteristics on many insulation types: PTFE (Teflon®), FEP (Teflon®), ETFE (Tefzel®), XL-ETFE (Tefzel®). The materials 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. Laser cutting is the complete removal and separation of material from the top surface to the bottom surface along a designated path. 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. Lasers have become one of the preferred means of marking wire and cable because of their reliability, throughput, cleanliness, and low maintenance requirements. 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. Ink jet marking is a quick method but it is also maintenance-intensive and inefficient. Universal Laser Systems logo and name are registered trademarks of Universal Laser Systems, Inc. All other company and product names are trademarks or registered trademarks of their respective companies. The mark is permanent and exhibits high contrast, making it an attractive alternative to inking methods. As a direct contract manufacturer or tier one/tier two service provider, our goal is to function as an extension of your operation. It is a synthetic fluoropolymer most noted for its anti-stick, water-repelling, chemical resistant and temperature resistant properties. In fact, Teflon is often used as a light diffuser at this wavelength. What types of laser sources are used for laser carbonization? 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. 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. The edges that result from laser cutting Teflon are smooth and free from discoloration sometimes associated with thermal processes. Laser material interactions almost always create gaseous effluent and/or particulate. Heat effects can be minimized by selecting an appropriate laser power for a given thickness of material. By continuously varying the laser energy, laser engraving can be used for textures, photographs, and information, such as text and numbers. Real leather only! Laser processing these materials creates dangerous gases or dust. However, the CO2 laser is ineffective at creating contrast. These gases and particulate should be routed to an exterior environment in accordance with government regulations. 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. Teflon is another great product to mark with a fiber laser. Ident Marking can effectively mark white or colored insulation including XLETFE, PTFE, FEP, ETFE or similar jackets.
