Smooth from Applied
A line of Teflon®-coated forming mandrels for catheter fuse
welding and tipping operations that are designed to optimise ID
quality and production speed are available from Applied Plastics.
Applied Plastics’ PTFE Natural® forming mandrels feature a
smooth surface that provides a 0.5 dynamic coefficient of friction
to prevent sticking, block tubing from shrinking, and simplify
catheter removal.
Allowing over 25 per cent elongation without flaking or failure,
these extrusion mandrels are chemically inert and can operate up
to 315°C (600°F) continuously.
Offered in stainless steel or nitinol, the mandrels can be supplied
precut in 0.127mm to 25.4mm diameter sizes with ±0.003mm to
±0.013mm tolerance, depending upon size.
PTFE Natural® grey is available with zero PFOA. A proprietary
surface preparation process before applying the coating assures
the coating will not flake or crack.
