PTFE Coated Mandrels for Fuse Welding and Tipping

A line of medical-grade, precision PTFE coated stainless steel or nitinol forming mandrels that are designed for manufacturing stent delivery systems is available from Applied Plastics Co., Inc. of Norwood, Massachusetts.

Applied PTFE Natural® Coated Mandrels are non-flaking and provide a smooth anti-stick surface that can withstand up to 288°C continuous, with excur-sions to 371°C.  Designed to prevent sticking and simplify catheter removal in fuse welding and tipping operations, these stainless steel or nitinol forming mandrels exhibit a 0.05 coefficient of friction per ASTM-1894.

Maintaining an inventory of over 50,000 pieces, Applied PTFE Natural® Coated Mandrels are available in sizes from 0.004” to 0.070” O.D., including many fractional sizes from 0.004” to 0.040” O.D. with ±0.0003” standard tolerances, custom to ±0.0001”, and precision cut lengths to 12 ft.

Applied PTFE Natural® Coated Mandrels are priced from $ 1.29 per foot, depending upon material, size, tolerances, and quantity.  Free stainless steel samples, pricing and literature 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.
