Principle of UV laser coding machine

1. The principle of laser coding machine is that laser coding has no thermal effect on the object it carries and will not cause deformation. Compared with mechanical impact marking machines, laser coding has no force on the parts and no mechanical contact.

2. Various graphics, text, and symbols can be printed under computer control, making it very convenient to change serial numbers or dates, including automatically printing the current year, month, day, hour, minute, and second, and tracking and changing these data in real-time during continuous production processes.

3. Laser inkjet printers can also handle many irregular objects with ease, with fast marking processing speed and instant completion, suitable for marking on mass-produced products.

4. As a measuring instrument, the instrument scale, caliper, and micrometer markings can all be directly marked with laser.

5. Choosing between a carbon dioxide laser or a solid-state YAG laser can be used for marking on many different materials.

6. For metal materials such as stainless steel, aluminum alloy, cast iron, copper alloy, titanium alloy, etc., it is necessary to use an acousto-optic Q-switched solid-state YAG laser as the marking light source.

7. Used for non-metallic materials such as plastic, wood, organic glass, rubber, leather, paper products, electronic components, etc. Gas carbon dioxide lasers are generally used as marking light sources.

Advantages of UV laser coding machine

The laser coding machines on the market now are divided into three types: ultraviolet laser coding machines, CO2 laser coding machines, and fiber laser coding machines. Among them, fiber laser coding machines and CO2 laser coding machines are inexpensive, have a long service life, are easy to maintain and operate, and have low environmental requirements. Compared to others, UV laser coding machines have a shorter lifespan and higher prices. Why is that? Today, I will talk to you about the reasons for the high price of UV laser coding machines.

1, Higher technical difficulty

The wavelength of the ultraviolet laser coding machine is 355nm, and the wavelength of the fiber laser coding machine is 1064nm. The wavelength of ultraviolet laser is the wavelength obtained by doubling the 1064nm wavelength through technology, which is more technically difficult, resulting in the price of ultraviolet laser being several times higher than that of fiber laser.

2, Optical accessories are not universal

Compared to the optical components of fiber laser inkjet printers and CO2 laser inkjet printers, the optical accessories such as mirrors and lenses of ultraviolet laser inkjet printers have different materials and coating thicknesses, making them not universal. The optical components of ultraviolet laser coding machines are also more expensive due to their special materials and processes.

3, High requirements for accessories

The UV laser coding machine is equipped with cooling devices to ensure stable operation of the equipment. There are two types of cooling equipment: water-cooled and air-cooled. Currently, water-cooled equipment is the main one on the market. Due to certain temperature requirements, excessively high temperatures can affect the operation of equipment, resulting in higher requirements for accessories and higher overall equipment prices.

Printing types: text, numbers, barcodes, QR codes, photos, patterns, production dates, production batch numbers, etc

Printing materials: various glass, textiles, thin ceramic sheets, monocrystalline silicon wafers, IC grains, sapphire, polymer films, and other materials
