laser technology used effectively on laser marking systems

by:Qingyu     2020-03-22
The laser is the mechanism by which the radiation (such as light or visible light) is emitted by the stimulated emission process.
The laser is the first letter acronym word amplified by the radiation excitation Emission Light.
More and more industries and competition between them will always force them to introduce the latest technology, which leads to laser systems in cutting, marking, stamping, engraving and engraving.
Compared to other forms of marking, the main difference between the laser marking system is the unique combination of speed, persistence, and the flexibility of computer control.
Access the software for the laser marking system through the PCI interface card.
This sends the digital signal based on the computer\'s marking or etching file to the motor and directs the laser beam to the product marked by the laser.
The lasers used for marking are: CO2 lasers-
It will create permanent code for lifetime traceability, which will reduce manufacturing costs and can be easily integrated with automated systems. Laser-
The following UV laser wavelengths are available: 157 nm, 193 nm, 248 nm, 308 nm and 351 nm.
It is mainly used for punching ink jet nozzles, eye lens marking, etc. YAG Lasers -
When it is configured correctly, it is most often used as a base platform for generating different wavelengths.
The most common wavelength is infrared (1064nm).
This wavelength is used to mark a variety of materials including metals, ceramics, composites and some plastics.
The different types of processes involved in the laser marking system are: surface annealing will extract carbon and/or oxide from the substrate for comparative marking.
The marking beam will produce a strong contrast line with the surrounding area, with little or no penetration.
This is great for applications that require smooth, undamaged surfaces and contrast.
Surface annealing is mainly used for medical implants, bearings, tooling, etc.
Surface etching is the ability to change the reflectivity of the metal and enhance contrast by changing the surface finish of the metal.
This is the most commonly used laser marking technology with a penetration depth usually no more than 0. 0001\" deep.
Ablation ablation is used to produce contrast without damaging the substrate, which is usually done using anodized aluminum, backlight buttons, and painted steel.
Thermal labeling this method controls heat by using different laser parameters such as marking speed, pulse frequency, power, and focus.
It is mainly applied to some alloys that cause color changes.
The depth required for engraving marks in this method is generated by evaporation of the substrate.
This marking form is the same as the surface etching;
This is usually used for 0. 0001\" to 0. 005\" depth.
Repeated passage increases the depth of the mark.
Professional Identification system commonly used in professional identification plastic.
In some plastics, changes can occur naturally by heating or coupling with the wavelength that causes chemical changes.
Most plastics can also use additives to get different colors.
An example of professional marking is product traceability, which is the ability of the manufacturer to track the product through its processing procedures and also the ability to re-
Trace the product back to the manufacturer.
