How Industries Increase ROI By Using Fiber Laser Marking for The Imaging Process

The majority of laser marking techniques involve engraving the mark on plastic or metal components or ablating the surface to reveal the contrast material beneath. Both processes typically require high-energy pulsed laser systems, and naturally, they also produce particles of the process.

Fiber lasers are now an effective industrial device with a distinct set of capabilities that permit an array of high-precision manufacturing processes for materials. Fiber lasers have low operating costs, an efficient ROI, a compact footprint, and a high degree of reliability, and thus have a increasing acceptance in the manufacturing industry using lasers as an economical alternative to traditional laser designfiber laser marking machine factory.

Laser marking can create high-contrast easy-to-read and long-lasting identification on a range of components used in industrial or products for consumer use. Computer-generated vector (also known as bitmap) patterns (logos or barcodes) can be engraved or etched with non-contact techniques on metal and nonmetallic substances which include plastics, metals electronics, glass PCBs, wafers sports items and packaging.

An amalgamation of trusted industrial laser, rapid and precise galvanometric imaging techniques and a user-friendly computer control system provides the manufacturers with a unique mix of reliability, speed, and flexibility that can’t be replicated by any other marking method.

Laser marking processes

Laser marking is traditionally engraving a physical marking onto a surface in the same way as conventional engraving techniques and causing a color change on the surface, or the etching of an outer layer of material that exposes another layer of material that is highly contrasted beneath. The two methods can be applied across a variety of materials. In addition to creating identifying marks, it may also be used as an element the industrial processes, like in the production of electronic components.

Laser marking’s advantages include speed, flexibility, and the non-contact marking process so that components are not strained due to laser marking. The non-contact method also helps to reduce maintenance costs since the equipment does not require replacement. Furthermore, laser marking is extremely repeatable and easy to read (even machine-readable).

Stringent Quality Control

Laser engraving is typically used for marking metallic surfaces since it’s fast, non-contact, and extremely long-lasting, but it is also responsible for the generation of debris , which is fine metallic particles that are removed from the surface in the course in the process of engraving.

Naturally, when it comes to manufacturing bearings, there are stringent requirements to processing debris. The marking of housings for bearings with lasers has historically included the “minimal” engraving process with an induced change to the surface color. CMS has been able to accomplish this by using Nd:YAG lasers however, demand from customers was seeking a way to get around the costs of maintenance, longevity, and reliability issues that come with the design of Ndya.

In this case, CMS engineers have pioneered the use the fiber laser of SPI Lasers plc of Southampton, UK – more specifically 100 W cw/modulated Fiber laser that is typically used for cutting and welding. SPI has been working on fiber lasers specifically for industries for a number of years, mostly for material processing such as micro welding or micro cutting and marking applications.

The switch to the new fiber laser will result in the exact thermally induced intensity mark onto the bearing housing however it is doing it without the production of any debris, with a lower recast and at a more convenient for the user which means virtually no maintenance, a longer life and incredible reliability.

The fiber laser that is that is used in this project exemplifies the range of applications for fiber lasers as tools to be used in a variety of uses. Marking applications are usually a reason to high-energy pulsed lasers. However, the performance capabilities offered through fiber lasers permits systems integrators such as CMS to create new domains for these applications.

Benefits of fiber lasers

Numerous different lasers have found their way into various materials processing applications. However, fiber lasers are changing the way these applications are conducted by combining enhanced optical performance, greater system flexibility, higher component yield, extended up-time, and unparalleled reliability.

Essential to numerous mark-making applications don’t show the weaknesses in spot size performance that can be found with other designs of lasers. regardless of power level as well as throughout all pulse sequences, and throughout the lifetime that the laser is operating, its size of the spot remains tiny, predictable and constant.

The tiny size of the spot and the high quality of beam also translate to that the beam has a high irradiance and manufacturing equipment equipped with fiber lasers are able to achieve better results faster and with less power. The laser focused on only a small portion of material, and has the advantage that only a small amount of heat is produced in the area around it. The highest quality precision marking cutting, welding and cutting may be done near (0.1 millimeters) in the case of the more difficult and intricate parts of the component.

With the assurance of reliable performance and the power modulation versatility, fiber lasers are often chosen for an upgrade over traditional flash-lamp-pumped solid state or DPSS laser technology in numerous other manufacturing industries with lasers. The continuous and better marking efficiency means lower cost of maintenance, longer time to times between maintenance and production, as well as improved quality which means less scrap. Lasers made of fiber are extremely physically strong and therefore ideal for the toughest of industrial settings.

All of these elements add up to a maintenance-free, plug-and-play system for integrators who want to reduce production, development and maintenance costs. They also have the benefit of being able offer the user more flexibility and a more efficient product. Not to mention the customer will be able to concentrate on their business needs rather than becoming laser maintenance specialists.

Benefits of industrial manufacturers

In general, the selection of tools for any task is based on determining the performance required, and then a compromise between initial expenditure as well as the yield of components, their uptime, and maintenance.

Not only are components getting more complex, yet, at the exact same time, increasing demands are placed on their functionality and quality. Manufacturing tools outfitted with fiber lasers that enhance process control could result in significant financial benefits to any company. In addition to the tiny footprint of these machines, they can help open up processes before unattainable to certain manufacturers.
