Catheter Forming Mandrels Huge Inventory and Fuse Welding & Tipping


A full line of PTFE coated 304 stainless steel forming mandrels offered in full and half sizes for manufacturing small diameter catheters are available from Applied Plastics Co., Inc. of Norwood, Massachusetts.

Applied Plastics’ PTFE Natural® Grey Forming Mandrels are made from 304 SS and feature a proprietary surface preparation process and a zero-PFOA PTFE coating that will not crack, flake, or peel. Designed for fuse welding and tipping operations, the firm maintains a 50,000 piece inventory in full and half sizes from 0.005” to 0.060” dia., cut from 6” to 73” long.

Unlike green pigmented PTFE coatings which can flake and have adhesion problems, Applied Plastics’ PTFE Natural® Grey Forming Mandrels maintain their integrity to prevent the tubing from sticking and block shrinking to simplify catheter removal. Forming mandrels can also be produced in custom sizes and can be manufactured from Nitinol.

Applied Plastics’ PTFE Natural® Grey 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.
