LASER METAL MARKING
This section can be split into three main processes called Additive and Subtractive
and Reactive all of which can be used to produce text, graphics, logos and Photographs on many different types of bare and
This method is so called because the process involves adding
another material to the work surface.
The bare metal is prepared by coating it with a silica based compound then we lase the details directly onto this, the heat of the laser fires the compound changing it to a ceramic material and fusing it to the surface of the piece on a molecular level. This produces a very durable almost indestructible black ceramic mark which is solvent resistant, abrasion resistant and UV resistant making it useful for marking medical instruments and manufacturing industrial serial or VIN plates; in fact it is so resistant that it is used by Space Agencies and the Military for marking their parts.
Enamel brass for example, which consists of a highly polished brass sheet covered with an enamel coating, then processed using the laser which removes the coating anywhere it contacts, resulting in the exposure of the polished brass below.
The availability of many different metallic sheet materials and coating colours on the market make this a very straight forward and cost effective method for producing very striking products such as dedication plaques, signs and promotional items.
ANODISED AND COATED METALS
Anodised coated aluminium is a very popular material at present and
can also be marked using laser processing.
This material consists of a very robust, resistive coating which is applied to aluminium sheet or finished products. The coating is available in many vibrant colours often used in the manufacture of flash lights, key rings and other promotional items. Standard matt finish colours can be used to manufacture industrial serial or VIN plates and signs.
When the laser strikes the anodised coating it
bleaches the colour from that point leaving a high contrast white mark without removing the actual coating or diminishing it’s original protective properties.
Laser Metal Marking is an extremely flexible process with many options and materials available so we are confident we can address any of you requirements, if you have any questions or would like a quotation please feel free to contact us.
