The B Case, C Case & E Case parts were marked in the applications lab. The parts were marked as specified in the blue prints included with the capacitors. The whitish parts marked very well with the 20 watt q-switched ytterbium fiber laser. The dark brown parts did not produce as much contrast, but it did still mark. The smaller parts in the A Case were not marked since the applications lab was not currently stocked with a short enough focal length lens required to create such a small mark. The cycle times for the B case parts was 0.08 seconds, the C case parts had a cycle time of 0.115 seconds and the E case parts had a cycle time of 0.2 seconds.  Read More…

Since there was not a rotary indexer configured at the time during the processing of this application, the most feasable solution was to rotate the parts by hand. The total marking area was broken into 3 sections. The 3 sections were all marked with the same parameters but did have different cycle times. The first part of the mark took only 0.96 seconds with the middle part taking only 0.79 seconds and the last part of the mark taking a 0.74 seconds to lase. Giving the total laser marking a time of 2.46 seconds. This laser marking time does not include the 2 rotations needed to complete the mark.

UID markings were marked with a 20 watt q-switched ytterbium fiber laser. The 160mm focal length lens has a working distance of 176mm from lens to part. The parts were marked with UID markings and text as requested per the stickers attached with the samples. The 2D codes were marked at heights of 0.5” and 0.75”. The part was marked on both the painted surface and the unpainted bare surface. In addition, a linear 1D barcode was marked for comparison purposes. The code was in an Interleaved 2 of 5 format. Unfortunately, the linear barcode was not able to be read in the apps lab. However, the 2D data matrix codes read very well in the lab, on both the painted and the bare surfaces. One additional note is that the data matrix codes on the bare steel seemed to read easier than those lased on the painted surface.

The part was marked using a 20 Watt Pulsed Fiber Laser using a 254 mm lens. Four passes were used to ablate the sample, 2 passes each in opposite direction. For the first 2 passes the sample was ablated using 5 Watts of power, frequency of 80 kHz, speed of 5" per second, resulting in a cycle time of 6 minutes and 54 seconds. The remaining 2 passes was ablated using 4 Watts of power, frequency of 80 kHz, speed of 20" per second, resulting in a cycle time of 2 minutes and 20 seconds. The total cycle time to mark the sample is 9 minutes and 16 seconds. The cycle time can be decreased by almost half the time if we are able to have more samples and time to be able to set up more efficiently. We did not want to damage the white base and ablate the black paint if we would have more set up time in order to do it with better quality and half the cycle time.

The various HMWPE (High Molecular Weight Polyethylene) were sent in for processing with our 20 watt fiber laser. The customer’s logo was generated and lased on all the various color samples and implants using various laser parameters to achieve the best overall contrast. Some colors responded better than others due to their individual absorption rates of the 1060-1070nm wavelength produced by the fiber laser.

By comparison to an Nd:YAG producing the same wavelength, the beam structure of the fiber laser is of a much higher quality (smaller spot size, higher energy density and is round/concentric versus a significantly larger beam size that is elliptical and not nearly as uniform). Many of the colored HMWPE parts were marked at 8 watts of power resulting in approximately a 3.5 second cycle time. The remaining colors required full power to create a contrasting mark at the 3.5 second cycle time. The orange sample did not result in any contrast.

Laser marking of the stainless steel tags was accomplished using the 20 watt q-switched ytterbium fiber laser, along with a 160 mm focal length lens. The tags marked with an annealed surface mark to create a darker mark. In order to get the sample darker with out increasing the cycle time, the amount of fill that was used to mark the logo was significantly reduced.

Two types of fonts were used one being bolder than the other. Both types of marks shared the same cycle time with-in a fraction of a second. The bolder font was marked using less passes. The cycle time for the marks were 29.67 seconds. The cycle time includes everything on the tag including the customer logo along with all variable information marked.

The parts were marked using a 20 watt q-switched ytterbium fiber laser with 160 mm focal length lens. The samples were sprayed with TherMark to create brightly contrasting marks. The marking on the cylinder had the same cycle time. There were additional marks made at a smaller size. The cycle time for the smaller marks was 16.86 seconds. The parameters were the same as the flat plates. Using the 160mm lens made it difficult to mark on the cylinder due to the roundness of the part. The edges of the mark became unfocused and caused the end result to look a little distorted. This can easily be remedied by using a larger focal length lens, such as the 254mm or 420mm focal length lens.

The parts were spread across the length of the field to demonstrate the capabilities of both the 254mm lens and the laser. Due to the lack of proper fixturing the parts were placed at the top, middle and bottom of the field. The parts were placed near the edges of the field to show that there was no distortion when marking near the limits of the marking field. The parts were marked with two sets of fonts. One font was a narrow font the other was a bolder font. This was done just to provide different options for visibility and contrast.

The high carbon steel darkened very easily using the 20 watt q-switched ytterbium fiber laser. The parts were marked using a 160 mm focal length lens. The short focal length lens produced a smaller marking area in regard to marking on the rounded portions of the part, due to the short depth of focus. To compensate for the distortion caused by marking on the rounded portions while out of focus, as seen on the second line of text on some of the previously marked samples, the text was slightly modified with the laser marking software. Modifying the text produced a mark that looked to be all marked in focus. The cycle time for the mark was 13.53 seconds. This time includes 2 passes for the logo and 7 passes on the text, multiple passes were used to produce a higher amount of contrast.

The samples were processed using the 20 watt Pulsed Fiber Laser equipped with a 160mm lens. In order to get the marks darker than what was currently being produced the beam was defocused approximately 6mm above the part. A low frequency was used to obtain the highest amount of beam intensity and a slow mark speed was used. The parameters that produced the best results were marking at 6mm above focus, 95% Power, 30 kHz and 1 “ per second mark speed. The mark darkens more and more with each consecutive pass, using 10-12 passes produced the best results during testing.

The samples were cut using the 200 Watt SMB 1200 FL cutting system. The PET film was cut using the pattern requested by the customer. While processing the samples an emphasis was placed on producing a cut with little to no residue left on the samples. The end result was a clean cut with crisp edges and minimal to zero residue. The only drawback while cutting the PET film was overcoming the air-bubbles contained in the protective layers. The drawbacks from the air bubbles were minimal and basically resulted in providing an opportunity for leaving residue on the sample, the air bubbles at times made it difficult to cut cleanly trough the protective layer. This occurance was minimal and the samples can still be easily removed once cut out. The final samples were cut out from a whole sheet using an array of 6x7 pieces.Read More…
