Foba C.0020-uv laser marks sensitive substrates without damage
1 min read
Foba's V.0020-uv ultra violet marking laser achieves high contrast marks on various plastics and highly sensitive products and substrates. Materials that were previously not damage-free markable, such silicones or white polyamides, can now be laser marked and remain undamaged.
The energy of the short wave UV laser light (355 nm) causes a photochemical reaction on the processed product. The product surface is altered with very little heat dissipation – a process referred to as cold marking. This makes Foba's V.0020-uv laser marker suitable for marking products such as aircraft cables, translucent or coloured tubes used in various industries, medical plastics for invasive applications, flame-resistant plastics for electronic housings and for glass.
The marker alters the product surface photo-chemically (instead of foaming the material) so that the product remains essentially unharmed. This is how permanent laser marks, resistant to typical sterilisation processes, can be achieved on medical devices such as catheters or insulin pumps, and this is also how filigree and brilliant laser marks can be applied on glass without breaking it.
Durable optical components and an efficient air-cooled design make the device both a low maintenance and an economical method of laser marking, says Foba. The possibility of marking products solvent-free and without additives also makes it an eco-friendly and consumable-free marking solution.
