FBS – Functionality By Structure


Injection moulding of sub-micro and nanostructures

We offer a sub-micro and nanopatterning service of free form injection moulding tool inserts. This allow for injection moulding of plastic parts with features down to 300 nm linewidth. The patterns are placed in a few micrometer thick hard coating on top of the injection moulding tool insert, which makes the features very durable.

The injection moulding tool inserts fits into existing injection moulding tools so no need for adjustments – but the injection moulding process must be optimized and fine tuned to achieve perfect replication of the fine features. We have named this technology Functionality By Structure (FBS®) because plastic products with new functional surfaces are created directly in the injection moulding process.
Possible application areas of the FBS® technology are:
  • Optical diffraction
  • Anti-counterfeiting
  • Labelling
  • Holograms
  • QR codes
More applications will be developed in the future.
The technology has been demonstrated for more than 100,000 injection moulding cycles without sign of degradation – even for the very fine 300 nm features. The FBS® technology is offered in collaboration with CemeCon Scandinavia (, a global market leader in the field of advanced surface treatment of tools and components.
