Microauthenfy for packaging: security and design integrated at the mould level

Packaging is no longer just a container. In premium and mass premium markets—cosmetics and perfumery being one of the clearest examples—it has become a brand statement, a trust anchor and, increasingly, a vulnerability. Counterfeiting, parallel markets and unauthorized refilling are no longer marginal problems; they directly affect brand equity, consumer safety and regulatory compliance.

How material and color influence Microauthenfy® visibility in injection-moulded parts

Microauthenfy® introduces a new class of integrated anti-counterfeiting, embedding a dynamic optical mark directly into the injection mold. Because the mark is physically engraved onto the tool, every part molded from that tool is inherently authentic—no labels, inks, additives, or post-processing required.

How to protect your product against counterfeiting

In an increasingly competitive global market, product counterfeiting has become a growing threat across many industries. Illegitimate copies not only lead to economic losses but also pose risks to consumer safety and cause serious damage to brand reputation. Facing this widespread challenge, which can affect any sector, Microauthenfy® offers an integrated authentication solution: microstructures inserted directly into the mould that guarantee the originality of each item from the very first stage of production.

Microscatt®: Precision mould texturing for controlled light diffusion

The introduction of LED technology in automotive lighting enabled sleeker designs, improved energy efficiency, and smarter functionalities. However, it also introduced new optical challenges — most notably, the issue of visible hot spots. Initially, some brands embraced these hot spots as part of their design language.
Over time, however, there was a clear shift toward achieving uniform, homogeneous light surfaces. This transition raised new constraints, requiring careful balance between aesthetic goals and optical performance.

How femtosecond laser is enhancing automotive lighting design and manufacturing

In recent years, there has been a clear trend towards miniaturization in the industry. Why? Because smaller means lighter, more efficient, more compact, and more sustainable. However, miniaturization comes with a major challenge: manufacturing precision at microscopic scales in a cost-effective way that ensures feasibility for large-scale production.
