Laserkennzeichnung

Laserkennzeichnung is a process that uses a laser beam to engrave or mark a surface. This method is employed across various industries for permanent identification and traceability of products. The laser beam, controlled by a computer, vaporizes or melts the material of the object being marked, creating a visible contrast. This process can be applied to a wide range of materials including metals, plastics, glass, and ceramics.

The advantages of laserkennzeichnung include its precision, speed, and non-contact nature. Because the laser does not physically touch the surface, there is no wear on tooling and minimal stress on the material, making it ideal for delicate parts. The marks produced are highly durable, resistant to abrasion, chemicals, and extreme temperatures, ensuring long-term readability. This makes it suitable for applications in automotive, aerospace, medical device manufacturing, and electronics.

Different types of lasers are used depending on the material and the desired marking effect. Fiber lasers are common for metal marking, while CO2 lasers are often used for plastics and organic materials. The complexity of the mark, such as alphanumeric characters, logos, or barcodes, can be easily programmed and changed, offering great flexibility. Laserkennzeichnung is an efficient and environmentally friendly marking solution due to the absence of inks or solvents.
