Nitinol Forming Mandrels Kink-Resistant For Long, Small Diameter Tubing


A line of bendable, PFOA free Teflon® coated nitinol forming mandrels for fuse welding and tipping operations that withstands high temperatures is available from Applied Plastics Co., Inc. of Norwood, Massachusetts.

Applied Plastics Nitinol PTFE® Natural Forming Mandrels are kink-resistant, making them ideal for fuse welding and tipping operations for long, small diameter medical tubing. Featuring a smooth surface with a 0.5 dynamic coefficient of friction to prevent sticking, these highly bendable forming mandrels are chemically inert and can operate up to 500°F (260°C).

Available in 0.0003” to 0.035” dia., with ±0.0001” to ±0.0005” tolerances, depending upon size, Applied Plastics Nitinol PTFE® Natural Forming Mandrels can be supplied in custom lengths. A proprietary surface preparation process before applying the PTFE Natural® coating assures it will not flake, crack, or peel and PTFE Natural® grey has zero PFOA.

Applied Plastics’ PTFE Natural® Forming Mandrels are priced according to size and quantity. Samples and quotations 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.
