Application examples made of plastic

A special type of annealing marking on metals involves color marking on stainless steel. Based on the technical possibilities with the MOPA laser, reproducible colors on stainless steel can be marked with a laser. For manufacturers of stainless steel products, this provides them with the opportunity to create special color designations, such as a company logo or functional markings like the indication for hot and cold on stainless steel fixtures.

Function and advantages of laser technology

  • 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 Leapion 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

  • 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 Leapion 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.

  • 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 Leapion laser

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

    • Belonging to non-contact processing, no damage to the product, no tool wear, good marking quality.

    • Thin laser beam is thin, small processing material consumption and the processing heat affected zone.

    • High processing efficiency, computer control, easy to automate

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

Permanent and cost-effective metal engraving and marking   The laser engraving and marking of metals is a very precise and clean form of metal processing. Advertising material or signs made of metal can be cost-effectively and permanently refined with texts, logos or images. The metal marking or engraving is done by the laser, without contact, and requires no pre- or post-processing. The annealing marking ensures an acid-, chemical- and corrosion-resistant marking without damaging the metal surface.

How does metal laser engraving work?

Metal laser engraving is mainly used for stainless steel, alloys and other metals. Depending on how much material is removed, laser engraving leaves a mark of varying depth on the metal surface. Material removal refers to the material being vaporized and the color changing. Due to the high energy of the laser engraving machine, it can directly vaporize other metals such as stainless steel and titanium. If the metal surface leaves a brown trace, it can be removed using other marking processes (see polishing process).

How does polishing work?

Polishing leaves white marks on stainless steel and other metals. Polishing is a "finer" engraving. The laser energy is lower during polishing, so less material is evaporated. Therefore, the polishing process removes less material and leaves white marks on stainless steel and almost all metals.
