Galvanized sheet

Galvanized sheet is a relatively common material used in the manufacturing industry.The galvanized steel sheet is used to prevent the surface of the steel sheet from being corroded and prolonged, and the surface of the steel sheet is coated with a layer of metal zinc.

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

precaution

In the process of processing galvanized sheet, auxiliary gas needs to be added. The purity and pressure of the auxiliary gas directly affect the quality of the cut sheet. The purity of oxygen used for cutting should be above 99.6%. When the purity of cutting oxygen is higher, the section of cut galvanized sheet is cut. The roughness and quality are also higher, and of course the cutting cost is also increased. The purity of nitrogen should be above 99.5% when cutting. Increasing the purity of nitrogen ensures that the slit does not change color during the process of cutting the galvanized sheet.


 

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

Advantages of fiber-cut galvanized sheet:

Fast cutting speed

 Easy to maintain

 Low processing cost

 Economical and efficient

Air cutting

The advantage is that the processing cost is extremely low. It only needs to consider the electricity cost of the laser itself and the air compressor. It does not need to generate high auxiliary gas cost, but the cutting efficiency on the thin plate can match the nitrogen cutting, which is economical. An efficient cutting method. However, the disadvantages on the cut surface are also obvious. First of all, the air-cut section will produce a bottom burr, and the laser processed product must also undergo secondary processing such as deburring, which is not conducive to the entire product production cycle. Secondly, the air-cut section is easy to blacken, which affects the quality of the product. Therefore, laser processing does not require the advantages of subsequent processing, so many companies are reluctant to choose the air cutting method in the processing of galvanized steel sheets.

Oxygen cutting

This is the most traditional and standard cutting method. The advantage is that the gas cost is low, and in the processing of sheet metal mainly carbon steel, it is not necessary to frequently switch the auxiliary gas, which is convenient for factory management. However, the disadvantage is that after the oxygen is cut, a layer of scale is left on the surface of the cut surface. If the product with scale is directly welded, the scale will naturally peel off after a long time. This is one of the reasons why galvanized sheet welding is easy to solder.
