CuttingTip FormingSide HolesBonding*
Clean & square Closed tip Burr-free drilled round, through one or both walls Tube mat’ls of differing hardnesses heat fused together giving seamless transition
2D & 3D angled Open tip Skived, burr-free with sharp edges Surface activation of low surface energy mat’ls with corona treatment*
Laser cut to maintain micro-bores below 50µm Soft tip Thermoformed with soft rounded edges Plasma treatment*
  Flanges: circular, elliptical, square, oval Punched, round or oblong Plasma etching, all with USP Class VI medical grade adhesives – UV or air curable*
  Irregular 3D shapes    
  Mushrooms    
  Atraumatic ID/OD radii    
  Tapered tip, L50mm max    
  Dilator tip    
  Flares, funnels    

*Tubing assemblies, of which the above tip formed tubing components could form a part, are possible. Suitable surface treatments can be determined by Polyflon in-house experimentation should bonding be required.
