Unalterable marking on thermoplastic materials
Unalterable colour laser marking for thermoplastic materials
The MICA Carnot Institute has combined the skills of two of its members, the Mulhouse Materials Science Institute (IS2M) and IREPA LASER, specialists in surface treatment and laser technology, to develop a marking technique that consists of pairing the marking ink and the laser to migrate the ink particles beneath the surface of the material. This marking, which requires no preparation of the surface, is thus made more resistant, in particular in the face of mechanical (scratches) or chemical (perfume) damage. This technique can now be used with colour thanks to the development of special inks, with the added advantage of 3D printing.
