Marking applications on aluminium

Marking and engraving on aluminium

Aluminium is a very common metal. Malleable and not very dense, it is a silvery-gray metal that does not alter very much in air. Some aluminium has surface coatings to improve resistance, but these do not exclude permanent dot peen and laser engraving.

Technomark Marking can produce laser and dot peen markings using its aluminium engraving techniques, without altering the properties of the parts, unlike chemical engraving. “Ablation” engravings range from superficial to deep (from 0.01mm to 2mm), and renderings can be light or dark, depending on the settings and the type of aluminium.

Dot peen engraving on aluminium

Dot peen technology is ideally suited to engraving aluminium. In fact, dot peen is a mechanical engraving technology that can produce markings on materials with a hardness of up to 63 HRC. Aluminium is less hard than this, and therefore tends to deform more easily than some other materials. This makes it easy to make deep markings quickly, without using the maximum force of your equipment. Recess engraving lets you add texture to your part with an aesthetically pleasing finish.

Laser technology for aluminium marking: embossed, black or thin.

Laser solutions are also ideal for marking aluminium parts. The different types of marking, whether annealed or material removal, work very well on aluminium parts to achieve high-contrast results. Moreover, renderings are even more contrasted when there is a coating on the part such as anodized aluminium, burnished aluminium or even painted aluminium. The laser can remove only the lightest layer to reveal the material in its raw state. This provides perfect legibility of the marking for easy proofreading by the operator or any other automated system.

Marking on treated and/or coated aluminium parts

Marking aluminium parts is a crucial step in the finishing process, with the aim of improving both the aesthetics and durability of components. Among the various coatings available, anodizing stands out by creating a protective oxide layer on the aluminium surface, offering corrosion resistance and an aesthetic finish. Zinc plating provides corrosion protection by depositing a layer of zinc on the aluminium surface. Nickel plating provides a bright finish while improving corrosion resistance. Polishing gives a smooth, shiny appearance, while chrome plating adds a layer of chromium for a tough, attractive finish. Sandblasting creates a matt texture by projecting abrasive particles onto the surface. Painting offers aesthetic personalization and additional protection. Finally, shot blasting involves projecting particles at high speed to clean the surface and improve adhesion of subsequent coatings. These various marking techniques contribute to the quality and appearance of aluminium parts, meeting the specific requirements of each application.
