Professional industrial coding and marking machines manufacturer
In the food industry, continuous Inkjet printers or CIJ printers have been widely used for printing production dates and expiration dates on the outer packaging of products. However, laser marking machines, also known as laser markers, or laser coders, have gained popularity in food packaging coding applications in recent years. This is due to advancements in laser technology, particularly the stability and maturity of laser components like ultraviolet lasers, as well as the reduced costs associated with these laser coders.
Laser marking machines can be classified into different types based on the laser wavelength they utilize. These include ultraviolet laser coders / UV laser coders (355nm), carbon dioxide laser coders / CO2 laser coders (10600nm), and fiber laser coders (1064nm). UV lasers feature a highly absorptive wavelength of 355 nm, this means more highly visible marks can be achieved with less power, ensuring a damage-free mark. UV laser coders offers several advantages compared with other types of coding and marking technologies:
High-Quality Coding: UV laser coders produce high-resolution, high-contrast codes, ensuring excellent print quality. The focused UV laser beam enables precise marking on various materials, including plastics, glass, metals, and films. This results in clear, readable codes that are less prone to smudging, fading, or being affected by external factors.
Permanent and Non-Removable Coding: UV laser codes are permanent and resistant to external factors like abrasion, chemicals, and moisture. This makes them ideal for applications where durability and traceability are essential, such as in the pharmaceutical, automotive, and electronics industries.
Versatile Application: Laser coders can be used for both on-the-fly marking, where the product and laser coder have relative motion, and static marking, where the product and the laser coder remain stationary.
Contactless and Non-Destructive: UV laser coding is a non-contact process that does not require physical contact with the product surface. This eliminates the risk of damage to delicate or sensitive materials. Additionally, UV lasers generate minimal heat, reducing the chance of thermal damage to the product.
Environmentally Friendly: UV laser coders use a clean, dry marking process that does not involve the use of inks, solvents, or other consumables. This makes them more environmentally friendly compared to inkjet or thermal transfer technologies that require ink cartridges or ribbons.
Low Maintenance: UV laser coders have fewer moving parts and do not require regular replacement of consumables. This results in reduced maintenance requirements and lower operating costs over time.
