Teflon® Coated Forming Mandrels Designed For Catheter Manufacturing


A line of Teflon® coated forming mandrels for catheter fuse welding and tipping operations that are designed to optimize I.D. quality and production speed are available from Applied Plastics Co., Inc. of Norwood, MA.

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% 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, Applied Plastics’ PTFE Natural® Forming Mandrels can be supplied precut in 0.005” to 1.0” dia. sizes with ±.0001” to ±.0005” tolerance, depending upon size. PTFE Natural® grey is available with zero PFOA. A proprietary surface preparation process before applying the PTFE Natural® coating assures the coating will not flake or crack.

Applied Plastics’ PTFE Natural® Forming Mandrels are priced according to size and quantity. Samples and quotes for Teflon coating services are available upon request.

Superior medical devices require superior coatings.

Our proprietary PTFE Natural® coated mandrels offer unmatched benefits.


Low Coefficient of Friction

PTFE Natural® coatings provide a coefficient of friction generally in the range of 0.05 to 0.20, depending on the load and sliding speed.



PTFE Natural® coatings can operate continuously at temperatures up to 550°F and can be used for intermittent service up to 600°F with adequate ventilation.



Non-Stick Very few solid substances will permanently adhere to a PTFE Natural® coating. While tacky materials may show some adhesion, almost all substances release easily.



Chemical environments usually do not affect a PTFE Natural® coating. Only molten alkali metals and highly reactive fluorinating agents are known to affect this coating.



The proprietary PTFE Natural™ coating process enhances the substrate bonding surface to provide optimum lubricity without flaking or cracking.



Since PTFE Natural® finishes are both hydrophobic and oleophobic, cleanup is easier and more thorough.
