In the past, watch manufacturers have used mechanical engraving or etching methods for functional part-marking to assist in identification and traceability in addition to engraving creative or personalized designs. Presently, laser systems are favored for marking and engraving due to their state-of-the-art technology.
Functional engravings such as serial numbers, batch numbers, or datamatrix codes, as well as decorative markings such as logos or graphics can be easily lasermarked on various watch components like clockwork parts, momentum wheels, bezels, crowns, housings, bottoms, or even clock faces.
Precision is undoubtedly one big advantage of laser technology, therefore, even the smallest and most intricate designs can be laser marked with high speed and precision. Galvo fiber lasers tend to be ideal for these applications, such as the SpeedMarker laser systems from Trotec.
Laser marking systems offer a unique flexibility, allowing the user to process different applications, sizes, various clock parts, as well as the ability to produce single pieces or larger batch sizes. The interface to ERP systems (such as SAP) enable the highest productivity, and the SpeedMark laser software can quickly process variable data according to individual orders with ease. This leads to shorter running times and minimum waste. There is also an option for a camera assistant system integration that enables more accurate mark-positioning.
Another big advantage of laser systems is that you can mark or engrave many different materials.
Watch manufacturers usually process:
- Stainless steel
All these materials can be optimally marked with fiber lasers.
For marking of other materials such as leather for wristbands, silicone and synthetic elastomers for seals, or indirect marking of sphire glasses, you can use CO₂ laser systems.
Trotec lasers can also be used for prototyping, e.g. for clockworks. Compared to serial production, watch manufacturers often use different materials for prototyping, and always single pieces that can change frequently. Besides the marking of metal parts, nontypical materials such as wood or acrylics are also processed.
For all these requirements of the watch industry, Trotec offers the perfect solution: Speedy flatbed lasers with flexx function, offering one laser system with two integrated laser sources (fiber and CO₂).
