Laser inscription offers new freedoms in the design and production of toothbrushes


Custom inscriptions in the soft thumb grips and ergonomic areas of toothbrushes? This is made possible with our optional laser unit, available starting immediately, while offering previously unseen benefits in ergonomics as well as hygiene and production! A new procedure is used to quickly and precisely inscribe customer and product logos, graphics, and fonts into the hard and soft components – right before packaging, with virtually unchanged surface smoothness.

The new laser unit supports pixels up to 0.025 mm, allowing for the permanent inscription of detailed logos, graphics, and images. Contrary to conventional laser procedures, which generally only work on polypropylene hard plastics, no carbonization takes place. The surface smoothness stays virtually completely intact as a result, while also retaining its resistance against ambient influences such as wear by frequent use or the effects of liquids containing propanediol or ethanol. What’s more, bacteria have fewer spots to attach themselves onto, providing great hygienic benefits in addition to the aesthetic and ergonomic advantages.

Flexibility – even among small batch sizes

The inscription takes place shortly before packaging into a Z.PACK, which massively cuts the time it takes to deliver an order. Producers need no longer hold production until the order arrives, but can rather use stored, neutral models. The inscription process itself takes less than a second per toothbrush. Thus, in contrast with other processes, such as pad printing, this system is already economical among even the smallest of batch sizes.

ZAHORANSKY complete systems with Z.PACK and Z.LODOS allow for equally efficient production of individually inscribed toothbrushes for “professional” use (dental clinics, dental practices) as for small niche markets or even customer-specific individual production. For the inscription process demonstrated at the K 2019 trade fair in Düsseldorf, the special composition of the soft components was realized using thermoplastic elastomers from Kraiburg as well as laser additives and effect pigments by Merck. However, for the implementation, raw materials from other manufacturers were also used.
