Aluminum is often anodized, i.e. provided
with a ceramic-like oxide layer to protect the material from abrasion or
natural oxidation. The layer also has a decorative
character, since it can be anodized in many colors.
CO2 or fiber lasers are suitable for
labeling the anodized surface. Classically, the CO2
marking laser creates a bright lettering (by bleaching), while fiber laser
systems mark dark as well as bright. In both cases, the effect
brought about by the laser is a color change.
Small defects in a ball bearing are often difficult to
detect, e.g. if single rollers
are missing , wrongly mounted,
or if a component is of a different size. If the undesired part is then labelled with a laser marker,
this causes unnecessary and relatively high costs. FOBA’s camera-based marking
solution offers an economical solution that integrates part detection, marking and validation of the
marked characters in a single, safe
Is your project time schedule tight? Do you want to get things right the 1st time? Then look at the following guidance what information to provide your laser supplier with to increase your chances of getting relevant and meaningful laser test results with the 1st trial:
Anodized aluminum appeared to be the perfect material for the FOBA application lab-team to create this year’s Christmas tree decoration. The glittering stars now contribute to the brilliant appearance of the fir tree in the entrance foyer at FOBA’s Selmsdorf headquarters.
There is a difference between marking time and cycle time for industrial parts marking. “Okay”, you might say. “So what? Does that matter?” The answer is simple: Yes, it does. At least, if a realistic throughput calculation matters to you. For example, in order to validate if you can meet the target output with your equipment, stay within the calculated costs per part, and plan your internal resources such as required production people correctly.
On January 14, 2020, Microsoft will end the support for Windows 7. After that you won’t receive any technical support or software updates via Windows Update for the protection of your PC! After January 14, 2020, your system as well as the application and production files on your PC will be more vulnerable to security breaches and viruses. Read through the frequently asked questions before you upgrade your system to Windows 10 to avoid data loss or failure of your marking system.
Hidden on the inside of a bottle cap you will often find laser-marked characters and codes, e.g. production data. An end-user might be much more interested to look “under cover” once there is a code to be found for participation in a sweepstake.
Due to traceability reasons, many parts and products have to be marked with codes. Finding room on a product to place traceability content is often a challenge. Manufacturers and designers tend to use every available space on the part to squeeze all tracking information required.
With the beginning of the cold and dark season, the heating needs to be turned on and the lights burn longer. It might be worth to take a closer look and discover how many of the operating elements inside the house are labelled with a laser mark.
For high-quality labeling of cardboard or packaging cartons, the marking field can be coated with a laser-sensitive lacquer. The additives contained in the paint react to the laser light with a color change. This results in high-contrast markings, usually in black on a bright surface, but also in white on a dark background.
