How are lasers used in manufacturing?
In terms of automobile marking, although there are several types of mold casting, electrocorrosive marking,
self-adhesive, screen printing, pneumatic marking and laser marking on the market, laser marking technology
is the latest, but laser marking is traditional. The advantages unmatched by processing methods are gradually
being recognized by more and more car manufacturers.
In the current automotive industry, we can see the laser application everywhere. Fiber laser marking machine
It can be said that the currentlaser technology is ubiquitous to change the current automobile manufacturing
industry. At present, laser technology has laser marking, hardening, cutting, welding, etc. in the automotive field.
Each process has different processing characteristics from the traditional process, and the current automobile
manufacturingindustry is obtained in terms of process and quality.
In recent years, with the introduction of national laws and regulations on automobile safety, high requirements
have been placed on the uniqueness of automobiles and parts. The establishment of the identity of automobiles
and parts is the basis for realizing product quality traceability and recall. Because laser processing is different
from traditional processing methods, laser processing is a marking method that uses a high-energy-density
laser to locally irradiate a workpiece to vaporize the surface material or cause a chemical reaction of color
change, thereby leaving a permanent mark. No need to touch the surface of the processed article, so any
shaped surface material can be marked and the workpiece will not deform and generate internal stress.
At the same time, laser processing is a fast and programmable process. The process is long-lasting, usually
not affected by the steps required in the production process, and is not affected by the harsh on-site environment,
and the marking is wear-resistant, and the production process is easy to automate. This is undoubtedly the best
marking processing solution for the automotive industry that pursues efficiency and quality.
At present, the application of laser marking machine in automobile applications includes automobile parts, engine,
label paper (flexible label), etc. Among them, laser bar code and two-dimensional code are often used for traceability
of automobile parts, which not only satisfies the recall system of vehicle defects. Requirements, but also the acquisition
of parts information and quality traceability, which has important special significance for the current automotive industry.
