Laser Engraving Heads Applications

Laser Engraving for Workshops and Woodworking Companies

One of the most far-reaching applications of Opt Lasers’ engraving laser heads is their capability to be used for marking, decorating, or aging wood. As of May 2018, there were approximately 13 000 registered carpenter's workshops and woodworking companies in Poland alone. What's more, woodworking is becoming increasingly automated nowadays. Consequently, the increase in the number of machines in the industry is directly reflected in the increased demand for engraving laser heads. In fact, there is a clear tendency to enhance pattern engraving processes by simultaneous operation of multiple engraving laser heads on a single CNC machine since doing so speeds up the whole process noticeably. Furthermore, the sheer opportunity of utilizing a compact engraving laser head and mounting it on an existing machine allows manufacturers to capitalize on new possibilities without having to resort to purchasing a whole new stand-alone CO2 plotter.

Laser Cutting in the Textile Industry

Engraving laser heads can also be used in the textile industry to cut, decorate and personalize fabrics such as cotton, polyester, viscose, naphthalene, felt, fleece, leather, upholstery and glass fiber among other fabrics. Opt Lasers cooperates with global market leaders to facilitate production of globally innovative products with our state-of-the-art engraving laser heads. An example of that were ingenious garments commissioned by a French fashion designer that were put on display at a 2018 fashion show in Milan. These garments were made on a machine equipped with twelve 6 W Opt Lasers’ cutting laser heads. According to an independent market analysis firm, there were approximately 8 900 business entities operating in Poland dealing in the production of textile products. The 2017 report also revealed there were about 26 700 clothing producing companies and almost 6 000 business entities producing leather and footwear. The number of companies operating in the textile industry grows by about 5% year by year. As the contemporary market strongly favours these enterprises that are capable to produce clothes in a time-effective manner, producers that utilized engraving laser heads and multi-head machines have been able to reap most benefits. 

Contemporary Architectural Designs

In addition, engraving laser heads can be used to produce architectural building models too. Showcasing physical layouts of designed objects is a popular form of project presentation among architects, because it is able to show intricate details of the building in a way computer simulations can’t match. According to business portals and the Statistical Office, approximately 16 500 architectural offices operated in Poland in 2018. Moreover, according to the Office for Competition and Consumer Protection, in the years 2014-2017, the number of active architects increased by 40%.

Manufacturing Steel Structures and Water Installations

With the help of laser engraving, it is possible to permanently mark metals with a laser in a cost-effective manner. Engraving lasers can be used in the process of production of steel objects and structures.Structural components require markings related to the date and place of manufacture, a detailed designation and specific operating conditions. According to business portals, the production of quality steelwork in Poland was estimated at 790 000 tonnes in 2017, which placed Poland as one of the top European steelwork exporters. With an ever-increasing processing power of engraving laser heads, the application of marking and engraving metals with blue lasers is becoming increasingly widely adopted. The Opt Lasers’ 6W engraving laser heads are capable of marking stainless steel and titanium. The continuous development of multi-head engraving laser technology will provide unprecedented solutions for the engraving and ablation of other metals such as carbon steel, copper, brass, and aluminum.

Universities and Research Units

Numerous qualities of engraving laser heads arouse interest from the research and academic sector. Laser ablation (i.e. the process of evaporation/removal of material from the surface of a solid) allows for a highly precise removal of small layers of material. Engraving laser heads operating at the wavelength of 440 - 450 nm also exhibit high absorption coefficient on a variety of metal surfaces. For instance, the absorption of 450 nm engraving laser light reaches 65% on copper in contrast to just 5% if IR engraving laser heads are used. Furthermore, the utilization of blue engraving laser heads gets rid of the ‘speckle’ effect that is a common issue on highly-polished and glossy surfaces. In contrast, red engraving laser light gets distorted by such surfaces and the speckle issue continues to persist. As a result, utilizing a blue engraving laser head will lead to lowered noise levels, normally by a factor of two to three compared to red laser sensors. Moreover, the utilized equipment is often very complex, which gives little freedom to access the sample of the material being tested. Notably, Opt Lasers’ engraving laser heads feature compact design that facilitates their efficient integration into larger research systems. Furthermore, engraving laser heads can also be used in research that is being carried out to enhance the currently known processes of plant breeding automation. Engraving laser heads can also be used to research modern methods of agricultural raw materials analysis as well as the neutralisation of small pests and weed seedlings. In fact, Opt Lasers currently cooperates with a great deal of scientific institutions around the world such as Nagoya University, the University of Oklahoma, Stanford University, the University of Sydney, the University of California, the University of Otago, the University of Sao Paulo, Uni Jena, and many others.

Medical Industry

Titanium is a lightweight and durable metal that can be extensively used in medicine. Furthermore, this metal can be easily marked with an engraving laser head. The human body treats this metal neutrally, which allows it to be used for the production of skull implants, bones, and stabilizers. Each titanium article is marked with an engraving laser to contain the relevant data. The ability to record the date of implantation directly on the item facilitates diagnosis in case of complications or issues with acceptance of transplants. Thanks to the compactness of the blue engraving laser, the physician can mark every single article needed with just a small device. Interestingly, using a 6 W engraving laser head, causes titanium objects to be marked (permanently changing their color on the surface) rather than engraved. Henceforth, marking titanium items with 6W blue engraving laser head does not affect their structure or strength, which is utterly important for marking implants.
