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.Read More
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.Read More
Fiber laser markers, be it pulsed or continuous wave, have prevailed in nearly all industries for marking products permanently and in high quality. The fiber lasers that are used for industrial part marking usually are either Q-switch or MOPA lasers. As of today, Q-switch lasers are more common because they have already existed on the market for a longer time. That is why they are sometimes called “standard laser”. But due to their high flexibility, MOPA lasers like the FOBA Y.0201 and Y.0201-DN, are an interesting alternative for many applications.Read More
In the previous article about data matrix codes (DMCs) you learned some basics. This article addresses questions which you will come across in your daily work with marking DMCs sooner or later:
- How can you optimize the DMC to increase its readability?
- How can you decrease the marking time for a DMC?
- How can you avoid that DMCs are incorrectly marked?
A data matrix code, or in short simply “DMC”, is a 2D code. In many industries DMCs have become the preferred way of encoding data, e.g. in automotive and medical industries. Machine readable data matrix codes are marked reliably, efficiently, permanently and abrasion-resistant with laser marking machines. But what do I need to know if I would like to mark products with data matrix codes? Read More
At the start of this year’s racing season, it’s also worth taking a look at the automotive components that are under the hood. A variety of metal or plastic components are laser-marked, including brake discs, ball bearings, pistons or gears, as well as door lock or steering wheel housings, pipes and conduits. Read More
Laser paint removal is the most advanced way of creating highly precise sharply contoured symbols on coated, translucent or transparent plastics. Day-night-design components carry signs that are backlit by night and safely distinguishable in any lighting conditions. These components are usually made of white ABS-plastic, like this automotive center console (see picture in the middle).
This time of the year, driving with searchlights on lightens up the outside darkness. Inside the vehicle, we hit the right switches when they are lit up from inside out. Their transparency and the backlit signs on them are created by highly precise layer removal. The basic plastic material has been coated by one or multilayer lacquer films. Defined areas of the underlying material are made visible by removing layers in a sophisticated laser procedure, called Day-Night-Design. Visible areas when backlit become graphic displays in the dark.
With multilayer coatings, creating different colors on one item is possible. High flexibility in applying variable marking contents, easily adjusting marking parameters to different colors and lacquers, as well as FOBA’s automated vision based part detection, make laser the most effective technique for day-night-design. Especially automobile, aerospace and electronics manufacturers benefit from the advantages of laser for processing backlit displays. Demanding day-night-design applications can best be realized with Nd:YAG-laser systems or certain fiber-lasers.
