Laser engraving and laser marking

Laser engraving and laser marking 

A laser for engraving/marking basically works the same way as a laser printer. The difference is the material. The laser printer dyes paper, whereas the laser engraver removes a thin layer of the material's surface and leaves a permanent surface, making it especially suitable for marking and decoration. 

Sheets or finished items are used for laser engraving. They all have in common that the surface preferably should have another colour than the rest of the item - painted, varnished, anodised, gilded etc. The laser engraver removes parts of the surface coating and creates a motif in the colour of the underlying material. 

This technique has two big advantages: 

- The engraving is placed inside the surface of the material and is not removeable, making it very suitable for identification purposes such as numbering, barcodes and data plates. 

- The launch costs are low. No costs for foils and fixtures, making it financially possible to laser engrave series of just one item to several. 

At Induflex, we mainly use laser engraving for identification marking and decorative purposes. 

Identification marking 

We manufacture custom-made laser engraved signs. The sheets are composed by raw materials of different colours and thicknesses. By engraving through the layers in different depths, it is possible to make multi-colour signs.  
Materials are available in numerous colours and thicknesses. 

We can also manufacture signs in black anodised aluminium, also very suitable for process diagrams.
