EMI uses holographic marking

In partnership with Morphotonix, a company specialising in nanotechnology and product-integrated brand protection, we have implemented holographic marking in some of our tooling.

We'd like to tell you more about this technology:

• What is it? It's a physical nano-engraving process that produces diffractive patterns with a precision of 130,000 dpi, without the use of inks or additives.
• How is it integrated? The pattern is engraved directly into the mould or insert using microstructures capable of reflecting light. During injection moulding, the pattern is replicated on the plastic part.
• What's in it for you? It guarantees the traceability of a part and identifies its route to the production site. Above all, it certifies the authenticity of the part, thereby helping to combat counterfeiting.
• What are its advantages? On the technical side, there is no change to the purity of the material, and no need to adjust injection parameters or the production cycle. What's more, engraving can be carried out on curved and inclined surfaces and can reproduce any colour, even complex designs or text. In terms of use, authentication is immediate and visible to the naked eye. The part can therefore be identified by consumers, manufacturers and control authorities. As for the environment, this technology uses no consumables and withstands more than a million injection cycles, so its carbon footprint is very low.
• What are the constraints? They only concern the quality of the steel and the finish of the initial surface of the insert. It must be mirror polished.
