Laser marking is a highly sought process of labelling workpieces in the fields of medical technology, jewellery, electronics, and automotive. Due to its versatility and precision, it is now the standard in businesses that require greater brand visibility and continuous product traceability.
The process, which is also known as 3D engraving, deep laser engraving and surface blackening, does not require pre or post-processing and delivers high-resolution finish with durable and element-resistant outcomes. It is ideal for engraving logos, instructions and texts on any type of material.
Different processes, same high quality results
Annealing or superficial laser blackening is the process in which the marking oxidises the surface of stainless steel, iron, steel or titanium through the local heating of the material, reaching the colour on the surface as deep as 30 μm. Laser engraving, on the other hand, involves the removal of materials from the surface of the metal, plastic, or ceramic. The laser beam penetrates the surface as the material is heated and reacts to ambient air.
Deep laser marketing is a procedure that is often likened to mechanical engraving but it is a highly specialised procedure than the latter. During the process, the material is removed in layers to make markings with a radius of a few millimetres. This is often recommended for difficult-to-machine materials.
