Application introduction

Plastics

Plastics can be marked or engraved with lasers in a variety of ways. With a fiber laser, you can mark many different commercially used plastics, such as polycarbonate, ABS, polyamide, and many more with a permanent, quick, high-quality finish. Thanks to the low set-up times and flexibility a marking laser offers, you can mark even small batch sizes economically.



Suitable metals for laser marking and engraving

  • Polyamide (PA)
    Polycarbonate (PC)
    Polyoxymethylene (POM)
  • Polyarylsulfone (PSU
    Polyethylene (PE)
    Polypropylene (PP)

INDUSTRIAL LASER MARKING

Examples of applications

Application examples made of plastic

"It is possible to permanently engrave almost any type of plastic, although the various raw materials, color pigments and additives (e.g. fillers, additives, flame retardants) react very differently. 

For laser marking plastics, the fiber laser offers you a range of different methods, such as dyeing, carbonation or foaming. Since various plastics react very differently, you should always test a material sample."



Industrial laser marking: Examples of applications

What is the point of buying a laser for industrial metal marking?

  • Why should I buy a laser for marking plastics?

    Non-contact laser marking is very fast as well as abrasion, heat and acid resistant. 

    Many different plastics can be marked or engraved with a laser 

    All kinds of contents including logos, codes, serial numbers and fully dynamic contents from ERP systems, etc. can be used 

    Even smallest components and details can be marked quickly and easily with the laser in difficult to access areas.

Function and advantages of laser technology

  • Function of the Fiber Laser Cutting Machine

    The fiber laser cutting machine can be used for both plane cutting and bevel cutting, and the edges are neat and smooth, which is suitable for high-precision cutting of metal sheets. It is an energy-saving and environmentally friendly new products with space saving and gas consumption and high photoelectric conversion rate.

    • Advantages of a Oree laser

    • Excellent beam quality and good cutting quality

    • Fast cutting speed and high production efficiency

    • No burr in the cutting, high cutting precision

    • Auto focus, easy to operate and maintain

    • Very low cost of use, cost-effective

    • Closed design, safe and pollution free

    • Fast cutting speed and high production efficiency


  • Function of the CO2 laser cutting machine

    The CO2 laser cutting machine adopts a focusing mirror to focus the CO2 laser beam on the surface of the material to melt the material, while blowing the melted material with a compressed gas coaxial with the laser beam, and moving the laser beam and the material relative to each other along a certain trajectory to form a slit of a certain shape

    • Advantages of a Oree laser

    • The output continuous laser is to make the cutting section smoothest.

    • The laser cutting head does not contact with the surface of the material and no damage to the workpiece.

    • Can cut non-metallic materials and has a wide cutting range.

    • No need for molds, saving production costs.


  • Function of the fiber laser marking machine

    Fiber laser marking machine, with the good beam quality. Its output center is 1064nm, the whole machine life is longer about 100,000 hours, compared with other types of laser markers. The electro-optical conversion efficiency is more than 28%, relative 2%-10% conversion efficiency of other types of laser marking machine. Besides that it has outstanding performance in energy saving and environmental protection.

    • Advantages of a Oree laser

    • Can process a variety of metal, non-metallic materials.

Foaming

Foaming leaves a tangible mark on the material. It can be seen as laser-induced boiling, which melts the surface. Due to the rapid cooling, bubbles are encapsulated in the material. These bubbles leave a positive mark, which is tangible. The laser works on a low power level and longer pulses. Foaming works on all polymers, but also on some metals. Depending on the material the mark is light or dark.


Carbonizing

Carbonizing enables strong contrasts on bright surfaces. During the carbonizing process the laser heats up the surface of the material (minimum 100° C) and oxygen, hydrogen or a combination of both gases is emitted. What's left is a darkened area with higher carbon concentration. The laser works with lower energy, which leads to slightly longer marking times compared to other processes. Carbonizing can be used for polymers or bio-polymers such as wood or leather. Since carbonizing always leads to dark marks, the contrast on dark materials will be rather minimal.


Color change

Color change on the material guarantees highest legibility. Laser marking with color change is basically an electrical process, which reorders the macromolecules (by changing the direction). No material is removed, but partial foaming is possible.  The laser works with a maximum pulse rate but low energy per pulse. Otherwise material would be removed or foaming might occur. Color change works on all polymers and the change of color can be bright or dark. Most color changes are dark.


Removing

Removing is used with multilayer plastics (laminates). During the removal process the laser beam removes the top layers, which had been applied to the base material. This results in color contrasts due to color differences in the layers.
