Laser marking on metal components is a high-quality way to produce permanent, non-contact markings on your production items. Because the process is non-contact, there are no post-processing steps necessary, and the end result is a high-resolution finish. It is also durable, corrosion-resistant, and easy to use for virtually anyone. With its versatility, laser marking is ideal for functional labels and production information. Whether you want to use your laser marking to create a personalized label or a unique part number, the process is easy to use for a wide variety of applications visit this website lasitlaser.pl
Applications
Many industries have found applications for laser marking on metal components useful. These include data matrix code identification and branding, as well as function-related markings on parts like shower heads and speedometers. Laser marking also meets stringent traceability requirements. As a result, laser marking offers several advantages, including the ability to create a storage medium within the component itself. For more information about the applications of laser marking on metal, read the brief manual below.
The process of laser marking uses different laser technologies. The selection of the right laser for the particular application depends on the quality and budget requirements of the manufacturer. In general, laser marking produces a permanent discolouration on the surface of the component. Surface oxidation may also occur, which allows manufacturers to mark parts without affecting their other properties. For example, laser marking can be used to create logos, inscriptions, or text.
Types of lasers
There are many different types of lasers used for marking metal components, but there are some common differences between these types. In general, lasers are used for marking metal for traceability features such as codes and serial numbers. Lasers are also used in industries like electronics, tool manufacturing, medical technology, promotional materials, and automotive. The different types of lasers for metal marking are discussed below. You can use the type of laser you need for your metal component’s marking application to determine which type of laser will be best for your needs.
The CO2 laser is one of the two most commonly used for marking metal components. It uses a high energy to penetrate the surface of the metal to create a permanent mark. This process is often preferred for marking stainless steel and other carbon-rich metal components. This method is more time-consuming, but it does produce permanent results. Depending on the type of marking you need, you may choose between black annealed marking and white engraving.
Costs
Traceability is a critical part of any manufacturing company’s supply chain. It allows companies to track production, source replacement parts, and even localize recalls. Precision laser metal marking services are offered by companies such as Superior Joining Technologies, Inc., an Illinois-based laser etching company specializing in metal identifying and serialization. The costs of laser marking are dependent on the complexity of the component, but overall, the benefits far outweigh the disadvantages.
Laser marking job shops often get their business from clients who don’t require high volumes of parts and don’t want to invest in a laser-marking machine. These laser-marking job shops usually operate at a shop rate of $60 to $100 an hour. In contrast, the costs of ink or labels per mark are significantly higher than the initial investment in a laser-marking machine. As a result, cost savings are derived by cutting out the need to stock these materials.
Safety
A recent literature review has found a very low level of evidence for the safety impacts of permanent laser marking on metallic medical components. One study showed that laser marking could decrease fatigue life and cause cracks that are more than 25 mm deep. However, this finding is unlikely to have a detrimental impact on safety. Further, a literature review found that laser marking is unlikely to produce fast fractures, but could have long-term effects on fatigue life.
A protective enclosure around the head is critical to preventing laser exposure. The laser controller must be equipped with an appropriate heat-reflectance enclosure. A safety shutter will close automatically after the laser is turned on. A remote interlock input is redundant. In either case, opening either terminal will stop all laser emissions. A protective enclosure should also be installed at the entrance to the laser area. The laser safety officer must be aware of any dangers and ensure that all laser systems are properly installed.
Durability
Generally, the maximum marking depth is determined using the stress concentrations along the crack length and the maximum deformation amplitude. The more depth that is marked, the lower is the fatigue life of the component. In addition, laser marking can also reduce the fatigue life of the component. These studies can help manufacturers improve the quality of their products. Consequently, they should focus on improving the durability of their laser marking processes.
Different materials have different absorption spectra, thereby causing different reactions to the laser beam. It is therefore necessary to consider the material’s melting point and its reaction to heat before selecting a laser source. For example, aluminum is softer than steel, so it should be treated before using a CO2 laser. Aside from that, coating the metal surface with a metal marking agent is essential. The lasers can cause the marking agent to vaporize, and users may need to wipe away the metal parts after the process.
