Cutting
Nylon Mesh
Edge view of 0.05” thick
multi-layer nylon mesh cut using Synrad 25W CO2
laser.
The multi-layer nylon mesh provided clean cuts with some bonding of the fibers. The cuts were made using 25W, at a velocity of 100ipm, 15psi air assist gas, and a 2.5” positive meniscus lens generating a 0.004” spot.
Marking
Electronic Components
0.02” Text marked on the ceramic
base of an electronic component.
The red ceramic material, shown in the above photo, provided contrasting marks using a Synrad 10W laser, a FH marking head, and 80mm lens. The marks were made using 5W and a mark speed of 10”/s, giving a cycle time of 0.2s. Black ceramic will also provide the same white contrasting marks. In addition to providing contrast, low power also reduces the amount of glazing and damage at the laser marked areas.
Marking
Codes on Boxes
Laser ablating an inked layer on boxes
is a popular method of marking date codes in the packaging industry.
This text was marked using a Synrad 25W laser, FH marking head and a 200mm flat field lens providing a 290 micron spot size with 5mm depth of focus. The inked layer was easily ablated using 18W at a speed of 45”/s, giving a mark cycle time of 0.3s. Using Synrad's WinMark Pro software users can easily change lot numbers and expiration dates. In addition to text, the software has a large library of codes including UPC, EAN, 128, 3 of 9, Code Bar, PDF 417, Postal Code, Data Matrix, and QR codes.
