In fact, Teflon is often used as a light diffuser at this wavelength. Users sometimes find that they are able to wip… Some materials have a propensity to generate flammable byproducts during laser processing. When Teflon absorbs laser energy, it rapidly converts optical energy into molecular vibrations (heat). Laser material interactions almost always create gaseous effluent and/or particulate. Delrin, Teflon, PEEK, and ABS are examples of medical plastics that are commonly marked by the laser plastics engraving process. 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. Laser carbonization can also be performed on organic carbon containing materials such as paper, cardboard and wood. Advanced Laser Marking, Etching and Engraving of Stainless Steel, Some Plastic, and Ceramic Parts . UV laser markings produce a high contrast marking which are non-abrasive. 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. 99. Engraving and marking are always done before cutting in a combined process. 2 laser beam: •Vaporization ... (teflon) Marking Example Name Also Known As Type Laser Wavelength General Cut Quality General Mark Quality Barcode Mark Successful Safety Fluropolymers PTFE, Teflon, EFTE Thermoplastic 10.6 µm 9.3 µm nGood: Some Alternatively, the effluent can be treated with a filtration system first and then routed to an exterior environment. Not 'pleather' or other imitations! Because different types of lasers react differently with metals, there are some considerations to be made. We offer a wide range of custom finishes to… In effect, hot stamping presses a hot mould coated with pigment into the wire’s insulation. Polytetrafluoroethylene (PTFE) is commonly known by the brand name Teflon®. The example shows a serial number marked on the surface of black Teflon. Our professionals are committed to working on any surface or materials used in different industries. For engraving on Teflon we use Fiber laser which operates at different frequency. Most laser markers will simply overpower a plastic surface with heat, which can lead to burning, bubbling, scorching, melting or otherwise damaging the material. The example shows a serial number marked on the surface of black Teflon. 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. As a direct contract manufacturer or tier one/tier two service provider, our goal is to function as an extension of your operation. Contact BCL to discuss your requirements. Marking. The mark is permanent and exhibits high contrast, making it an attractive alternative to inking methods. Laser material interactions almost always create gaseous effluent and/or particulate. Laser wire marking doesn’t damage the wires as other methods can. Laser cutting is the complete removal and separation of material from the top surface to the bottom surface along a designated path. In the case of Teflon, the processes of laser cutting, laser engraving, and laser marking can be applied. LASELEC’s Laser wire markers have no problem marking on Teflon wires, as they cannot smear or run over the wire. Laser marking is a high quality, durable identification method for use with high performance electrical wires and fiber optics used by the aerospace industry. Teflon is the material that is made into very thin sheets and referred to as “Baker’s Sheet” or PTFE. Polytetrafluoroethylene (PTFE) is commonly known by the brand name Teflon®. Products made with Teflon® fluoropolymer resins cut well even though they have exceptional resistance to high temperatures, chemical reaction, corrosion, and stress-cracking. While CO2 laser cutter and cut Teflon, it cannot engrave it. Teflon can be engraved cleanly without discoloration or melting. Fiber lasers operating at 1.06 µm are also ineffective at creating contrast on pure white Teflon. However, the CO2 laser is ineffective at creating contrast. Laser type: CO₂, Flexx or Fiber laser : Work area: 610 x 305 up to 1016 x 610 mm : Max. Teflon is an excellent absorber of CO2 laser energy (wavelength=10.6 µm). 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. Major Laser Technologies UV Laser Marking. Tri-Star Technologies is a leader in laser wire marking for military and aerospace applications. More time is required for marking metals with a CO2 laser, for instance, because of the need for coating or pre-treating with a metal marking agent. CO2 Laser. When properly controlled, the polymer will begin to boil, creating more surface area. The edges that result from laser cutting Teflon are smooth and free from discoloration sometimes associated with thermal processes. Laser cutting Teflon will produce a fine powder of PTFE particles that can be easily cleaned with a dry cloth. Teflon is usually chemically pure, meaning no plasticizers or fillers are added.
