Quantum–Cut Polymer

Polymer removal from metal substrates is a common requirement in the medical device and micromanufacturing industries. Using advanced laser processing techniques it is possible to selectively ablate a material from the surface, without damage to the material beneath.
Used in conjunction with laser annealing technology it is possible to produce a perfect cut on braided structures without unravelling.

  • Selectively remove material from the part without causing damage to the structure
  • Cut braided structures without unravelling
  • High reliability and yield
  • High speed, high throughput
  • Flexible & Customisable
  • Fully CE compliant
