Laser marking leather Trainers Application – adidas UK
Most of the sports – leisure shoe manufacturers are providing custom generation within their product range. This is a good example of the type of thing we can do. Although this clearly indicates a celebrity product branding, Adidas are also offering laser marking for company and personal branding as well.
The CO2 wavelength, is the most suitable for laser marking natural organic materials such as this. The laser brands into the surface effectively tattooing the skin as a branding process. The darkness is achieved due to good contrast levels between the white skin and the burning of the leather. One major issue is the quality of the leather. I am informed that the quality of the leather is directly related to the amount of oils used in the tanning process.
The poorer the quality, the higher the level of oil content. This directly relates to the potential for flare up during the marking process. Flare up is when the oil catches fire. Normally this would only be for a very short time period, but the flame will damage the mark edge and stain the materials. This staining is not very easy to remove. So great care has to be taken when setting up and running these materials. It is important that extraction is set high, so that any flare off is pulled high and away from the materials to reduce or eliminate staining of the material.
Limitations will be around spot size of CO2 source. These wavelength lasers with galvo based beam delivery modules tend to have larger spot sizes than other wavelength laser. This can restrict flexibility especially if very small character generation is required.
