Can a CO2 laser engrave aluminum?

Carbon dioxide laser marking machine is mainly used for non-metal (wood, acrylic, paper, leather, etc.), widely used in electronic components, electrical parts, medicine, food, crafts, leather products, plastic products and other industries. However, there are some problems in engraving metal with CO2 laser marking machine

1. Dot matrix engraving dot matrix engraving is similar to high-definition dot matrix printing. The laser head swings left and right to carve a line composed of a series of points each time. Then the laser head moves up and down at the same time to carve multiple lines, and finally forms a whole page of image or text. Dot matrix engraving can be used for scanned graphics, text and vectorized graphics.

2. Vector cutting is different from dot matrix carving. Vector cutting is carried out on the outer contour line of graphics and text. We usually use this mode to cut through wood, yak grain, paper and other materials, and we can also mark on the surface of various materials.

3. Engraving speed: engraving speed refers to the speed of laser head movement, usually expressed in IPS (inch / second), high speed brings high production efficiency. Speed is also used to control the depth of cutting. For a specific laser intensity, the slower the speed, the greater the depth of cutting or carving. You can use the engraving machine panel to adjust the speed, you can also use the computer's print driver to adjust. In the range of 1% to 100%, the adjustment is 1%. Hummer's advanced motion control system enables you to achieve ultra-fine carving quality at high speed.

4. Engraving intensity: engraving intensity refers to the intensity of the laser beam on the surface of the material. For a specific carving speed, the greater the intensity, the greater the depth of cutting or carving. You can use the engraving machine panel to adjust the intensity, you can also use the computer's print driver to adjust. In the range of 1% to 100%, the adjustment is 1%. The greater the strength, the greater the speed. The deeper the cut is.

5. Spot size: the spot size of laser beam can be adjusted by lenses with different focal lengths. The lens with small spot is used for high resolution engraving. Large spot lens is used for low resolution engraving, but it is the best choice for vector cutting. The standard configuration of the new device is a 2.0-inch lens. Its spot size is in the middle, which is suitable for various occasions.

CO2 laser is generally used in CO2 laser marking machine, but the power of laser tube used now belongs to the medium and small power range. The maximum is 300W. Originally, metals absorb less of this medium wavelength laser. So CO2 laser marking machine is generally not used to carve metal.

The scope of application of the three common marking machines is as follows:

CO2 laser marking machine: can be widely used in electronic components, electrical parts, medicine, food, crafts, leather products, plastic products and other industries.

Semiconductor laser marking machine: it is especially suitable for applications requiring fine marking and high precision. It is used in electronic components, hardware products, tool accessories, integrated circuit (IC), electrical appliances, mobile communication, precision instruments, glasses, clocks, jewelry, auto parts, plastic buttons, building materials, PVC pipes, PPR pipes, medical devices and other industries.

Optical fiber laser marking machine: it is widely used for marking graphics and characters in many fields, such as integrated circuit chips, computer accessories, industrial bearings, clocks and watches, electronic and communication products, aerospace devices, various auto parts, household appliances, hardware tools, molds, wires and cables, food packaging, jewelry, tobacco and military affairs, as well as mass production line operations.

Therefore, it is very important to choose the right laser marking machine. We can make a reasonable choice according to our own industry needs.
