Laser Engraving is a technique that uses a high energy laser beam to etch or carve on the surface of a material. Unlike traditional printing techniques, laser etching printing physically or chemically removes part of a material's surface to form a permanent mark, pattern or text.
Here's how it works: a laser produces a high-energy laser beam, usually a carbon dioxide laser, a fiber laser, or a solid-state laser. The laser beam is focused and guided by a series of optical elements, such as lenses and mirrors, to precisely illuminate the surface of the material. The laser beam generates high temperatures on the surface of the material, causing the material to vaporize, melt or chemically react, thereby removing a part of the surface of the material and forming an etching pattern. At the end of the etching process, the surface of the material is cooled and the remaining debris and fumes are removed by airflow or other means.
Its main features are:
High precision: Laser printing can achieve extremely high precision and is suitable for etching small and complex patterns.
Permanence: Etched patterns are permanent and not easily worn, faded or tampered with.
Multi-material compatibility: Laser Engraving technology is suitable for a wide range of materials, including metals, plastics, glass, ceramics and wood.
Non-contact processing: Laser Engraving is non-contact processing, does not apply mechanical stress to the material, suitable for brittle and precision materials.
Strong anti-counterfeiting ability: Laser Engraving can create complex anti-counterfeiting features, increase the security of the card, prevent counterfeiting and copying.
Fast and efficient: Laser Engraving technology can quickly complete personalized processing, improve production efficiency, and adapt to large-scale production needs.
The application field of Laser Engraving technology is very wide, in the field of industrial manufacturing, it can be used for parts marking in the automotive, aviation, electronics and other industries, such as serial numbers, batch numbers and brand identification. It can be used for marking and decoration of tools and molds to enhance the professionalism and brand image of products.
In the field of medical devices, it can be used for the marking of medical devices and equipment to ensure the traceability and safety of products. It can be used as a marker for medical implants, ensuring their long-term stability and traceability in the body.
In the field of consumer electronics, it can be used to mark and decorate the shell and parts of consumer electronic products such as mobile phones and laptops. It can be used for marking and micromachining of printed circuit boards (PCBS).
Similarly, Laser Engraving technology has also been widely used in the field of smart card making machine, mainly for personalized card processing and security features enhancement, and can greatly improve the quality of smart card products.
In terms of personalized information printing, Laser Engraving technology can be used to print the cardholder's name, photo, signature and other personalized information; Key information such as card number and expiration date can be accurately printed to ensure clear and lasting information.
In terms of security features enhancement, Laser Engraving technology can be carved on the surface or inside the card to create security features that are difficult to counterfeit, such as miniatures, complex patterns and holograms; You can add anti-counterfeiting marks on the card, such as invisible text, color-changing patterns, etc., to enhance the anti-counterfeiting ability of the card. It can be used to print high-precision bar codes and two-dimensional codes for quick data reading and verification. It can be combined with other coding technologies to ensure the accuracy and security of magnetic stripe and chip data.
In terms of improving quality, Laser Engraving technology can print high-resolution images and patterns, which is suitable for cards that require beautiful design such as membership cards and gift cards. The company logo and brand elements can be accurately reproduced to enhance the professionalism and brand image of the card.
Several of PIOTEC's smart card personalization devices already use Laser Engraving technology. The newly launched bank card personalized flexible production line FPL3000 are integrated with the latest Laser Engraving technology in the industry.Laser Engraving technology will continue to evolve, and PIOTEC's personalized smart card products will bring you more perfect experiences.
