The durability of laser marking processes on metal components is a key factor to consider before using this process. The maximum depth at which the marking can occur depends on stress concentrations along the component’s length and deformation amplitude. The more marking is performed on a component, the shorter the fatigue life. Laser marking is a great way to improve the quality of your product. Consequently, manufacturers should focus on improving the durability of their laser marking processes visit this website lasitlaser.pl
Fiber lasers
Choosing the best material for laser marking depends on the requirements of the application. Different materials have different absorption spectra and react to different wavelengths of laser light. You must consider the temperature of the component, its hardness and the metal’s melting point when choosing the laser source. Aluminum is softer than steel and will melt at a lower temperature. However, if you want to add branding or traceability to a medical device, you should use a higher-power fiber laser.
Although CW lasers produce a continuous beam of light, fiber lasers produce short pulses of light. Each pulse is measured in nanoseconds. Fixed pulse width fiber lasers produce identical laser pulses, while variable pulse width fiber lasers vary the pulse frequency. Pulse frequency will affect the number of laser pulses striking the part and the amount of laser energy contained in each pulse. When laser marking on metal components, the shorter pulses are more suitable.
CO2 lasers
CO2 lasers are used for marking on metal components, including aircraft and automotive parts. This process leaves a permanent mark that cannot be altered. It also reduces environmental pollution as compared to other marking methods, such as inks and glues. Laser marking is also maintenance-free, lasting for up to 100,000 hours. It is highly reliable and produces high-quality markings for metal components. The following are some advantages of CO2 lasers for laser marking on metal components.
CO2 lasers are used for metal marking, since they do not degrade the material underneath, making them ideal for industrial applications. CO2 lasers do not require any pre-treatment, making them a versatile and cost-effective option for a number of industries. However, CO2 laser marking machines require high operation and energy requirements, which make them an expensive purchase. For industrial marking, CO2 lasers are more effective.
CO2
CO2 laser marking on metal components can create a high-quality mark without affecting the surface of the metal. The laser produces a mark that is bonded on top of the metal without removing any material. The process does not affect the strength or tolerance of the metal, so it is suitable for marking painted or coated metal components. Here are some of the advantages of CO2 laser marking. Read on to learn more.
Lasers emit a specific wavelength, so it is important to understand what wavelength a given material can absorb. Metals are most susceptible to a CO2 laser wavelength, so it is vital to first coat the metal with a marking agent. CO2 lasers must be operated at a high power setting with low speed, but this can be problematic if the marking agent is washed off the piece before the marking is complete.
Green lasers
One of the most important requirements for manufacturers is the ability to produce permanent traceability markings. The green laser has the capability to mark a wide variety of materials, including delicate metals, computer chips, foil, magnetic cards, and other materials with low absorption ratios. Due to this, Telesis developed a variety of green lasers with various wavelengths, allowing it to mark almost any material. Green lasers are especially good for marking metals, as they are able to mark 2D codes on them.
Green lasers are solid-state devices that generate a beam of energy by interacting with a semiconductor material. They generate a green light by converting YAG infrared laser radiation (1,064 nm) to energy at 532 nm. This wavelength is optimal for marking silicon substrates. But there are several drawbacks to green lasers. First, they’re less stable than other lasers.
Dual-source lasers
There are many benefits to using dual-source laser systems for laser marking on metal components. These machines increase versatility and capability, but they also have a drawback. While dual-source lasers offer better versatility, they’re useless if one is in use. Listed below are the pros and cons of using dual-source laser systems. They can be useful for engraving, marking, or cutting a variety of metal components.
Dual-source lasers are designed to combine fiber and CO2 lasers. This enables dual-source systems to process mixed materials in one step, including wood, acrylic, steel, leather, and metal components. These dual-source lasers also allow the operator to adjust the intensity of the laser beams to achieve the desired result. A dual-source laser is a great choice if you’re in need of fast and reliable results with minimal downtime.
Olefin components
Various types of metal particles have been used in the Laser marking process on Olefin components. In particular, D50, D90, and D99 are used. These metal particles are of various sizes, which enhances the precision accuracy of laser marking. Furthermore, a laser beam is used to label the desired plastic mould. Hence, Olefin components can be effectively marked by laser. Here, we will discuss the benefits of laser marking on Olefin components.
A master batch with laser marking additive is present in a form of compacted pellets, strands, or granulates. Their size ranges from 50 mm to 80 mm. For a larger quantity of material, a master batch with a high-performance laser marking additive may be produced. A spherical metal particle may be added in powder form to improve the laser marking process.
