The automotive industry has always been one of the driving forces behind innovative laser applications. Continuous further development of automobiles with special regards to performance, reduced fuel consumption and improved environmental friendliness; employs millions of people around the world.
Medical Device Technology
Products in the medical device industry have to meet highest quality demands. Laser technology as a precise and extremely selective material processing method is steadily gaining importance in this industry. One of the major reasons is that laser technology fulfills the high quality requirements to perfect, hygienic clean surfaces, dross-free and free of any material residues. As laser cutting or welding is a wear-free process, it delivers consistent high-quality cuts and joints.
Minimally invasive surgery techniques, miniaturized implants – numerous products in the medical device industry are becoming increasingly smaller. Lasers are ideally suited for cutting widths and weld seams in the range of only a few microns and provide extremely gentle processing.
Machine Tool Industry
Lasers that are used as cutting and welding tools have become indispensable for general machine construction. There is hardly a sector today where lasers are not successfully proving their value, offering a variety of benefits in industrial production. Thanks to clean cut edges, reliable weld seams and flexible guidance systems, high-power lasers have conquered a considerable market share, especially in sheet metal processing.
The processing spectrum is manifold: various components are marked flexibly, durably and with changing contents, flat sheets with thicknesses of 25 mm are cut by lasers or gearwheels, injection nozzles, fire extinguisher housings and heat exchangers are welded. Furthermore, Lasers are used for the production of Tubes and Profiles that are cut by lasers or welded, thanks to intelligent system solutions.
In Jewelry market, there is a wide range of new technologies available to enhance the ability to provide the highest level of quality, craftsmanship and service to their clients. One of the fastest growing technologies is the use of laser systems for jewelry as an alternative to traditional methods of welding, engraving and cutting of metals.
In the consumer goods industry, the packaging of the product is almost as important as the product itself when it comes to influencing the consumer’s buying decision. Modern packaging must be well presented, be fit for purpose regarding storage requirements, and be easy to open. In addition to this there are a number of other challenges for food and packaging manufacturers: safe transport and storage, control of freshness, attractive presentation on the shelf, as well as easy preparation and treatment.
The suitable laser source for any technique: depending on the application there is a wide spectrum of laser sources which are appropriate for laser processing in the plastics industry: CO2 lasers for cutting, diode lasers for welding, diode-pumped solid state lasers and fiber lasers for marking.
Tool and Mold Making
The tool and mold making industry offers various possibilities for the efficient use of laser processes. Laser deposit welding has established itself as a high quality and efficient repair method forming, punching or die casting tools. The laser selectively hardens tools and components at particular stressed areas. For durable markings it offers marking and engraving functions.
Electronic industry products consists of various materials. Besides copper and ferrous alloy, mainly plastics and composites are used. In this context we usually talk about mass products that are produced fully automatically in large quantities, which is why speed and stability of the production process is so important.
Due to these benefits the laser is the ideal tool for wear-free and very fast material processing for various applications. Beside the proven standard solution the laser always provides new processing methods that top conventional solutions by far when it comes to precision, speed or even environmental compatibility, e. g. the efficient and wear-free processing of composites.
In the semiconductor production, the material processing with lasers is standard. This ranges from Marking of wafers to Marking and Separating of completed components to defect analysis. Besides silicon, metallic materials (lead frames and housings) and plastics, especially epoxy resins of grouting materials are processed too.
For the majority of the applications today, diode pumped semiconductor lasers are used in the basic wavelength of 1064 nm and in versions with doubled and tripled frequencies. The partially extreme demands on highly specialized processes in the semiconductor production are responsible for the fact that fiber lasers with comparable long pulse lengths and low pulse peak performances had only little success until today.
Due to its low heat conductivity and brittleness, glass is not easy to process in industrial processes. The risk of breakage has to be minimized during production as well as for subsequent use due to tensions and micro-cracks caused during the production process. CO2 or Nd:YAG lasers open up a range of innovative possibilities for cutting, joining and marking of glass.
LEDs are expected to develop to one of the predominant light sources over the coming decades. They are already used for backlighting of flat panel televisions, mobile phones and the interior lighting of modern cars. Laser marking is an essential step in manufacturing the required LEDs
