Laser Marking and Etching

  • Laser Marking and Etching

Laser Marking

Many manufactured and imported components need branding or marking in the form of logos, serial numbers, product codes or user instructions and warnings. EU compliant components need CE marking and many components need traceability. Using a laser to mark this information gives a permanent, aesthetic and non-damaging solution. Parts can be directly marked and this can be useful where labels must be avoided.

The precise, repeatable nature of lasers allow the fine detail marking required on smaller components and the accurate removal of coatings.

 

 

The laser beam width can be focused to less than 30 microns and it can be repeatably positioned to the same magnitude.

Materials which can be marked include metals (Stainless steel, aluminum, gold, silver, titanium, bronze, platinum, copper), plastics (ABS, polycarbonate, polyamide, PMMA), composite materials (fiberglass and other advanced composite and laminated materials) and organic materials (wood, stone, glass).

Laser Etching

 Very much as it sounds, a precisely controlled laser beam is used either to discolour the surface of a component or to vaporise material. The laser parameters and the laser’s position can be precisely controlled to provide high contrast marks in the form of barcodes, logos and graphics.

If a surface is painted then the laser can be used to precisely remove paint. By choosing a translucent substrate that is a contrasting colour a graphic can be backlit for night and day readability.

 

 

Common materials that are laser etched include anodized aluminium, coated metals, foils and films, or laminates and painted plastic components. 

Such process is used widely in the automotive and aerospace industries on backlit buttons and also by the general manufacturing industry on coated metal components.

Laser Engraving

Laser engraving differs from laser marking based on the fact that engraving removes material. The amount of removed material depends on the depth of your designs. The overall process is slower than laser marking but the engraved mark will be a permanent and everlasting.

The precision and aesthetic features of laser engraving permits to illustrate complex drawing on a wide array of materials.

 

 

Materials that can be engraved are ranging from plastics (acrylic, styrene, silicate, bakelite, PVC), metals (coated metals, stainless steel, steel, aluminium, anodized aluminium, gold, silver, copper) stone, wood and glass.

Such process is used in many industries from aerospace to general manufacturing, fine art and high end jewellery.

Extra Laser Services

Whilst our lasers are primarily used for marking and etching other applications include laser cleaning and laser de-burring.

Laser Cleaning

This process removes any kind of sediment deposition on almost any given material without using external chemicals, abrasives, water which could be sources of potential damage when restoring any type of item.

This process is not just sustainable by not producing any secondary waste, but also enhance historic surfaces in an unprecedented way that could not be achievable by any other methods.

 

Laser Deburring

This process enables fast, selective edge finishing on plastic and metals work pieces. Loose fibber ends are being removed by laser beams offering a precise and smooth end result.

This process is as any laser process sustainable and environmentally friendly by not using any chemicals, abrasives which could also potentially damage the item during the process.
