6 Application library Laser marking application cases on the following markets: Automotive Aeronautics Electronics Metal Work Medical Packaging General Industrial And more Last updated on 12/11/2010 7

7 Surgical tools surface marking for traceability purposes MEDICAL Hospitals and medical environments in general, in addition to demanding accuracy in non-disposable tools cleaning, look for traceability methods to manage huge amounts of tools. Datamatrix codes can solve this issue, but marking must not involve any modifications of the metal surface. Also, the marking system must fit strict space requirements, looking for small footprint in hospital technical departments. DLA s Ulyxe 6W infrared laser marker can easily fit into small marking equipment, and its 1064 nm wavelength achieves high-contrast 2D marking on tools surface, making them easily readable despite metal reflection. The tools have subsequently passed through over 1000 sterilization cycles without any significant fading or signs of rusting. Ulyxe 1064 nm F-theta = 160 mm 2D resolution: 12 mils, 7 mils, 4 mils 8

8 Identification marking on general-purpose metal keys GENERAL IND. The customer request was to mark short texts and identification logos on the heads of general-purpose keys. Given the extremely high production rate (5000 pieces/day), the marking time for a single element shouldn t be more than 4 seconds. To mark short text strings, Ulyxe nm compact laser marker - with a standard f=160mm lens - is the perfect solution for both plastic and metal heads in 2 3 seconds per piece. After a later customer request of a fast way to mark complex logos and symbols, we proposed V-Lase 20 W infrared laser marker as a good-quality marking solution on all materials. Depending on the complexity of the logo, the marking time varies between 0.5 s and 1 s. Ulyxe 6 nm V-Lase nm F-theta = 160 mm F-theta = 160 mm Marking time = 2 3 s Marking time = s 9

9 Direct laser marking on silicone cattle tags GENERAL IND. The request was to provide a compact laser solution to mark animal tags in order to serve decentralized service providers for local laser re-tagging of animals. The challenge was reducing the marking time down to 10 seconds for the overall animal tag pair (the tag and the round button). Selecting the appropriate laser and filling parameters enables the Ulyxe 6W compact laser to perform a fast marking with dark gray contrast on both yellow and orange colored tags. The required marking time is 8 seconds. With the use of a higher power IR laser source such as V3+ 27W, the cycle time can be pushed down to about 3 seconds per piece, without any significant loss of marking quality. Ulyxe 1064 nm F-theta =254 mm Marking time: 8 s V nm F-theta = 254 mm Marking time: 3 s 10

10 Fast marking on plastic automotive components AUTOMOTIVE The customer needed a very fast marking solution on the plastic shell of mechanical actuators for the automotive industry. Simultaneous marking of several pieces arranged in a planar layout was required. The marking consisted of alphanumeric strings for traceability purpose. DLA s V-Lase 20 W laser marker can provide excellent contrast by changing the color of the black surface of the samples. F-theta lens with 420 mm focal length provides a marking area whose size complies with the customer requirements. The marking time per piece is less than 0.4 seconds. V-Lase 1064 nm F-theta: 420 mm Marking time < 0.4 s 11

11 Engraving on black rubber automotive valves AUTOMOTIVE The request was to engrave the product code, a bacth code and the company logo on black rubber valves used in the automotive industry. The huge production rate required a very short marking time of 0,2-0,3 seconds. Thanks to the wobble function, able to mark thick paths in a single passage, a V-Lase 20W equipped with a standard f=160mm lens perfectly matches the customer requirements. V-LASE 1064nm F-theta = 160mm Wobble = mm/s Marking time = 0,2s 12

12 Marking on electrical equipment to replace inkjet technique ELECTRONICS The customer was looking for an automated solution to replace inkjet marking on the surface of metal covers for electrical equipment. The total marking area is about 160 x 30 mm. Both text strings and numbers should be marked, as well as small geometric figures and logos. The cycle time shouldn t exceed 1 minute. DLA s V-Lase 10 W laser marker can achieve superb grey-on-white contrast and excellent readability of even the smallest features. Due to the size of the marking area, f-theta lens with 254 mm focal length is equipped. The time required to mark the complete pattern is approximately 1 minute. V-Lase 1064 nm F-theta: 254 mm Marking time: 1 min 13

13 Marking of identification labels on DIN modules ELECTRONICS The request of the customer was to mark identification and traceability labels on the surface of plastic (ABS-PC blend) covers for electrical equipment. The maximum required pattern size was 60 x 35 mm and the marking time shouldn t exceed 10 seconds. ZEUX nm compact laser marker, together with a standard f=160mm lens, perfectly matches the customer requirements. The cycle times are 1 second and 7 seconds for the front and lateral sides, respectively. ZEUX nm F-theta = 160mm Marking time = 1 7 s 14

14 Permanent marking on metal carbide tool inserts METAL WORK The customer needed to mark short text strings on small carbide tool machine inserts. The marking had to be permanent and easy to read, and the required cycle time was 0.5 s or less. Both V-Lase 20W and Violino 3+ 27W infrared laser markers are suitable for this kind of application. The higher laser power delivered to the sample by Violino 3+ allows faster marking. The cycle time needed to mark on the side of each sample is 400 ms for V-Lase 20W and 150 ms for Violino 3+, respectively. V-Lase 20W Violino 3+ 27W F-theta = 160 mm F-theta = 160 mm Marking time = 400 ms Marking time = 150 ms 15

15 Identifying brass and nickel plated hydraulic joints METAL WORK The customer request was to mark alphanumeric strings on nickel, brass or stainless steel pieces used in hydraulics. The marked pattern had to be clearly visible and resistant to corrosion. DLA s Violino W laser marker equipped with a standard f=160mm lens matches the customer requirements. The cycle time per piece is approximately 5 seconds. Violino nm F-theta = 160mm Marking time = 5 s 16

16 Identification of stainless steel machinery tools METAL WORK The request of the customer was marking the company logo and a set of symbols and text strings onto cylindrical steel tools. The samples had to be mounted on a rotating device in order to write quickly on a large portion of the surface. The marking time (40 seconds maximum) was of great interest for this application. Violino nm laser marker, equipped with an f=254 mm lens, meets the customer requirements. The amount of time needed to mark the whole pattern is 35 seconds for the steel samples and 3 seconds for the black-colored nickel-plated tools. Violino W F-theta = 254 mm Marking time 3 35 s 17

17 Marking on cylindrical plastic valves using a ring divider AUTOMOTIVE The request was to mark alphanumeric strings and small logos on the outer surface of cylindrical plastic (PBT/GF35) valves. During the productive process, the pieces were mounted on a rotating device. DLA s Violino nm equipped with a standard f=160 mm lens perfectly meets the customer requirements. A ring divider is used in order to mark on the cylindrical surface, whose diameter measures 32 mm. The amount of time required to achieve good contrast is about 3.2 seconds. Violino 1064nm F-theta = 160mm Marking time = 3.2 s 18

18 Deep engraving of numeric codes on car engine parts AUTOMOTIVE The customer wanted to replace a pin marking system with a direct part marking technique. A numeric string and an omega symbol had to be engraved "as deep as possible on an aluminium car engine part. Saving 15% of the allowed max cycle time, DLA's Sagitta 1064 nm equipped with an f=100 mm lens is able to grant good-quality, clean and deep engraving. The reduced maintenance requirements (broken pins to change, lubrication of moving parts, etc...) and the possibility to change layouts just by typing on a PC keyboard or receiving data from a server, are some of the pluses offered by a laser system, when compared to a pin marking system. Sagitta 1064 nm F-theta=100mm Marking time ~ 8.5 s 1919

19 Annealing on stainless steel immersion pump body GENERAL IND. The customer a manufacturer of immersion pumps requested to mark the information plate directly on the pump body. The expected production rate required a marking time within approximately 30 seconds. DLA s Sagitta 60 W, together with an f=254 lens, is suitable to match the customer requirements. The marking process only changes the color of the surface without affecting its resistance to corrosion. Sagitta nm F-theta = 254 mm Marking time: ~ 20 s 20

20 Datamatrix marking on silicon wafers for PV industry SOLAR Manufacturers of photovoltaic solar cells deal with polycrystalline silicon, which is highly sensitive to mechanical stress. Traceability data must be hidden in corners and involve as little surface as possible. Laser direct marking is the solution to increase productivity and throughput. It s possible to mark 1x1 mm 14x14 dots 2D codes. DLA s Green-Lase 532 nm laser marker grants both high speed and good quality. The 160 mm f-theta lens covers up to 100 x 100 mm marking area. Green-Lase 532 nm f-theta = 160 mm Marking time = 0.35 s

21 Traceability of black nylon automotive components AUTOMOTIVE Direct laser marking technique to replace inkjet printers. 2D code and alphanumeric text traceability on black thermoplastic polyamide (Nylon Zytel 0G/33) used as electric component s body in the automotive industry. Quite good brown-on-black contrast on Nylon Zytel 0G/33 can be obtained with 532 nm laser marker. All the 2D codes are easily readable with DLA s Matrix200 code reader. Depending on the font size and the graphic complexity, traceability marking requires less than 2 seconds: - 2D code 5x5 mm; - 17 alphanumeric characters, 1.6 mm high. 532 nm f-theta = 160 mm Marking time < 2 s 22

22 Traceability marking on hard to mark medical plastic MEDICAL UHMWPE (ultra-high molecular weight polyethylene) is a very important material in medical applications, like joint replacement. Serial and lot numbers are required in production: infrared lasers aren t effective because the surface of the material reacts irregularly. The marking has to be readable, permanent and non-dangerous for the human health. DLA s Green-Lase 532 nm laser can effectively mark UHMWPE in human readable applications. Small bursts are produced by the laser spot, resulting in a nice visual effect. It is demonstrated that the marking process doesn t affect the mechanical properties (namely, the resistance to tensile stress) of the samples. A 160 mm f-theta lens covers up to 100 x 100 mm marking area. GreenLase 532 nm F-theta = 160 mm Marking time: n. a. 23

23 Car window traceability using datamatrix codes AUTOMOTIVE The customer requested a laser marking solution able to grant effective traceability of car window glasses (floating glass) by using datamatrix codes. Perfect readability of the code through the entire production process (including temper), together with unaffected mechanical properties of the glass, are fundamental requirements. The customer asked us to find the best solution choosing among a CO 2 laser, a green laser and an UV laser. The maximum amount of marking time was 5 seconds. DLA s UV-Lase was found to be the best marking solution to meet the customer requirements. Unlike infrared and green light, UV light marks the datamatrix inside the glass, thus making it permanent through all the following treatments. Moreover, the glass does not lose its mechanical characteristics (e.g. resistance to tensile stress). UV-Lase nm F-theta = 100 mm marking time < 5 s 2D resolution: 12 mils, 7 mils, 4 mils 24

24 Glass Substrate Traceability on Solar Cells SOLAR Traceability through datamatrix codes, alphanumerical codes, or both, is highly recommended in solar cells glass substrate production. But laser marking on one side of the panel might affect also its opposite side, where a very thin TIN coating is applied. Thus accurate and selective laser marking is required. When DLA s UV-Lase laser marker is adjusted to focus on the uncoated side, there is no effect on the opposite side of the thin glass substrate. Since traceability marking requires small sizes, a marking speed between 50 mm/s and 150 mm/s provides high throughput, depending on fonts and graphics. UV-Lase nm F-theta 100 mm 2D resolution: 12 mils, 7 mils, 4 mils 25

25 Color change traceability code on painted aircraft parts AERONAUTICS Replacing the inkjet technology with a laser marking solution to mark a visible logo and alphanumeric codes on aircraft components. It is a critical application because the laser beam has to interact only with the paint (a special protective ceramic-based paint), without damaging the sample surface: therefore, only a change of color is required. This condition must be fulfilled; indeed damaging or removing the protective paint is dangerous for these kind of aeronautic components. The customer needed a 100 x 100 mm marking field. We obtain good results with our Violino 355 nm laser marker. This kind of radiation allows to change the color of the protective paint without removing it. A power of 300 mw is enough to reach these amazing results: - Permanent and untouchable marking - Cold process marking (no heat generated by laser beam) - 100x100mm marking field (focal f=160mm) - All advantages replacing the inkjet technology - High-speed marking (90 s for 0.01 mm-filled pattern) - Excellent contrast (barcodes or 2D-Codes easy to read) 26

26 Marking on fly on adhesive labels for pharmaceutical industry PACKAGING The customer was seeking a way to obtain thermal marking on adhesive labels stuck to plastic test tubes (Ø 12 mm). The required pattern was an alphanumeric string (patient name and identification number) and a bar code, to allow quick traceability. Additionally, marking on fly technique (30 mm/s) had to be used, so the ideal time to mark the complete pattern was 1 second μm CO 2 laser marker, equipped with an f=100mm lens, is able to mark the desired pattern with excellent black-on-white contrast. The labels are extremely sensitive to laser light, thus allowing very fast thermal marking. All the barcodes can be read with conventional code readers μm F-theta = 100 mm Marking time ~ 0.8 s 27

27 Marking of expiration date on cardboard package PACKAGING The customer wanted to mark the expiration date and the batch code onto cardboard used in food packaging. The date string had to be 5 mm high, while the code 2.5 mm high. Additionally, the customer requested that the marking be performed at a linear speed between 40 m/min and 80 m/min, which gives a maximum marking time between 185 ms and 100 ms, respectively. EOX μm CO 2 laser marker, equipped with an f=100mm lens, is capable of marking the desired information in single-line font, resulting in excellent readability on differently colored cardboard. The amount of time to mark the whole text is 100 ms, thus allowing a line speed of about 80 m/min. EOX μm F-theta = 100 mm Marking time: < 100 ms 28

28 Traceability marking on aluminum car pistons AUTOMOTIVE The request was to mark a single 5x5mm (16x16 modules) datamatrix code for WIP traceability on piston side, then to mark a 10x10mm (18x18 modules) datamatrix code on piston head together with a logo, human readable code and the company logo within 3.5 seconds. Despite the challenging request of marking such a huge amount of information in a very short time, the request is perfectly matched by a 27 W air cooled Violino 3+ laser, equipped with a 254mm f-theta lens. Violino nm F-theta = 254 mm Marking time = 3.5 s 29

29 Traceability on automotive steel components AUTOMOTIVE Direct laser marking on steel for car industry metal parts. Surface marking should be performed within 10 seconds: - 2D code: 31 characters, 10x10mm - alphanumeric string: 10 characters, 2.5 mm high The marking has to resists to a wet polishing process removing the oily protection film. The customer request was exactly matched with a configuration composed of a Violino 3+ and a 160mm f-theta lens, achieving a dark contrast. The datamatrix is easily readable with a Matrix 400 code reader. Violino nm F-theta = 160 mm Marking time = 10 s

30 Identify black PA66 car devices AUTOMOTIVE Marking black PA66GF30 car devices is a quite common request. In this case the request was to grant a quite high production rate with a marking time within 0,4s to compete against Keyence 30W fiber laser (MD-F3000W). Thanks to the excellent beam quality provided by all the V-LASE laser models expressively tied to the marking applications a V-LASE 20W equipped with a quite long F=420mm f-theta lens perfectly matched the requested marking time providing a bright white contrast. V-LASE 1064nm F-theta = 420 mm Marking time = 0,4 s 31

31 Traceability on automotive plastic components AUTOMOTIVE Direct laser marking to replace of inkjet printers: 2DCode and alphanumeric test traceability on Black Thermoplastic Polyamide (Nylon Zytel FE54/22) used as electric component s body in Car Industry. Very good contrasted white marking: 2dcode easy readable by Datalogic matrix2000. Traceability marking, according to fonts and graphics, requires less than 2sec marking time: -2Dcode 18x18 5x5mm -17 alphanumeric characters, 1.6mm highs. Green-Lase, 532 nm F-theta 160 mm Marking time: n.a. 32

32 Matrix and Bar Codes on Polypropylene car devices AUTOMOTIVE The Customer needs to write different codes (barcode, datamatrix code, alphanumeric code and manufacturer Logo) on a black polypropylene material (PP GF30) obtaining good read rate. These parts are assembled on an automatic line therefore the marking time have to be as short as possible (max.6 sec. each piece). This kind of material reacts with a very good contrast (white color) at low frequency (8000 Hz-10000Hz) and with a low laser power. For this reason why the best laser source to this application is V-Lase 10W marker (IR@1064 nm) with a 160mm lens. In this application the laser marker replaced the old inkjet technology with a lot of advantages: 1.Permanent marking 2.Reduced maintenance costs 3.Cleaner environment 4.No paint-disposal costs 33

33 Barcode marking on PV panels aluminium frame SOLAR Solar panels are manufactured on a fully automatic line. Data have been laser-marked on the aluminum frame profile, black and silver aluminum alloy anodized. After lasering the laser marking have been verified by a barcode reader in order to check the result. DLA s Zeux laser marker, 1064 nm wavelength, achieves both speed and quality. 160 mm F-theta lens cover up to 100 mm marking area nm F-theta 160 mm Marking time: ~ 20 s 34

34 Coding of Heating Elements for Major Domestic Appliances GENERAL IND. A leading company in Major Domestic Appliances and Industrial Applications requested to mark on a metal frame of the heating element a readable code together with several functional information.a key request was the longevity of the marks meaning that the marking must resist for a long time to the corrosion and still be readable. Marking time for all the task should be less then 4 seconds each piece in order to grant the expected productivity. The expected results are achieved by using a V-Lase 20W completed by the standard focal lens of 160mm length. The brown contrast text strings are clearly visible while marked in less then 3.6 seconds. The markings resisted to corrosion tests performed by the customer simulate the complete life cycle of the product. V-Lase 1064nm F-theta = 160(S) mm Marking time < 3.6 s 35

35 Metal engraving on security door keys GENERAL IND. The request was to identify the metal door keys by engraving a human readable code and optionally a barcode on the key body. The engraving depth should be enough to grant marking permanency after further polishing processes the keys was undergoing while the marking time must not exceed 3 seconds. Several runs was executed to meet the customer requirements that finally was meet by using a 27W Violino 3+ equipped with a 63mm shorter f-theta lens. Violino nm F-theta = 63 mm Engraving time = 3 s 36

36 Color change on plastic immersion pump body GENERAL IND. The customer manufacturing immersion pump was requesting to mark the information plate directly on the pump plastic body. The expected production rate required a marking time within approximately 30 seconds. The orange colored PA66GF30 immediately appeared to be very hard to mark by using standard infra red laser sources while Violino UV running at 355nm easily performed better then expected marking whit a suitable contrast. Violino UV nm F-theta = 160 mm Marking time less than 15 s 37

37 Plastic floating ball pen refill laser personalization GENERAL IND. The request was to provide a marking solution for ball point pen refills in order to permanently print on it several information (such as the company logo, the product code, etc) helping anti-counterfeiting. Marking time was a challenging constraint, to provide the expected productivity rate, to be kept under 0.5 seconds each. The Violino 3+ laser equipped with an f-theta lens of 254mm was selected to perform a fast marking with perfectly readable gray contrast within the expected cycle time. Violino nm F-theta = 254(S)mm Marking time less then 0.4s 38

38 Color Change on Medical Equipments MEDICAL Internal use plastic medical equipments marking must be permanent and smooth. No material leakage or friction is allowed inside the human body. Moreover, small size is an important requirement too. Urinary catheters represent such a case. Customer s request is to mark a readable scale, made of ticks and numbers, on these 3 mm diameter pellethane tubes. Material color is white, so dark contrast is what we re looking for, without any surface foaming or burning. DLA s UV-Lase laser marker, with its 355 nm wavelength, is able to change the surface color from white to grey. Scanhead and 160 mm. F-theta lens covers up to 110 mm marking areas. UV-Lase 355 nm F-theta 160 mm Marking time: n.a. 39

39 Logo and text marking on metal medical implants MEDICAL CoCrMo and AISI 630 alloies are largely used in medical implants. When customization or traceabilty marking is needed, after the laser process, the part must undergo special treatments and the surface must be not engraved. Nevertheless, the marking must remain visible. DLA s VLase 10W laser marker, 1064 nm wavelength, can achieve readable and treatment resistant marking, without exposing the surface to oxydization. Here s a knee part implant case and a generical part case. 160 mm F-theta lens cover up to 100 mm marking area. VLase 1064 nm F-theta 160 mm Marking time: n. a. 40

40 Marking on single-use plastic baby bottles using additives PACKAGING Our partner's customer, a main packaging company, is planning to change ink-jet marking on the bottles with laser. Our goal is to obtain the best (human-)readable marking on the bottle in the max cycle time of 1"60. Earning roughly the 10% on the max cycle time, the solution proposed is the following: Sagitta 60W + f-theta 330mm This configuration seems to be the best to join both the low cycle time and the well visible marking. Another important issue is the very light burning on the bottles' surface. 41

41 Laser soldering of power electronics contacts A new soldering process to replace manual positioning and oven-welding. Copper Top-pin or Pack-pin covered with a silver-tin alloy must be soldered on a DBC substrates (Direct Bond Copper), composed of a ceramic insulator, Al2O3 onto which pure copper metal is attached by a high temperature eutectic melting process and thus tightly and firmly joined to the ceramic. DBC High thermal conductivity prevents any contact based soldering techniques. DLA s KUBO 100 laser welding system can quickly and easily solder the pins because the high peck power overcomes the thermal conductivity effects. KUBO 100, 1064 nm Fiber delivery 42
