Extruded Tubing

Core Mandrel 

Used as a manufacturing aid for braid- or coil-reinforced catheter tubing, our core mandrels feature extremely tight tolerances to maintain consistent diameter and roundness for catheter manufacturing.

Core Mandrel

PEI acetyl core spool

Core mandrels provide enhanced frictional properties and significantly improved release characteristics resulting in a lower release force for catheter development.

Material Options:

  • Premium plain acetal
  • Premium acetal blend with silicone surface
  • Acetal or silicone acetal with stainless steel wire reinforcing
  • Economy version

Specifications

  • Sizes range from 0.010"–0.250" (0.254 mm–6.35 mm)
  • Finished mandrel tolerances from 0.0005” (0.0127 mm) on small OD mandrel to 0.003” (0.0762 mm) on large OD mandrel
  • Highly consistent diameter, roundness, and smooth surface for easy removal
  • Optional level wind on mandrels >0.070" (1.778 mm)
    • Level winding maximizes the amount of material on the spool
    • Assists with consistent flow and improved process performance when unwinding the core during the braiding process
  • Samples available
