Catheter Forming Mandrels Restored Fully by Strip & Recoat Service


A service for refurbishing damaged fuse welding and tipping mandrels used for manufacturing catheters that restores them to pristine like new condition is available from Applied Plastics Co., Inc. of Norwood, MA.

Applied Plastics’ Forming Mandrel Strip and Recoat Service strips the old Parylene® and Teflon® coatings from fuse welding and tipping mandrels and applies a new PTFE Natural® coating that will not crack, flake, or peel. Ideally suited for larger diameter mandrels 0.020” and up, this precision coating service lets users recondition rather than discard worn mandrels which saves delivery time and eliminates grinding; especially with complex configurations.

Featuring a smooth anti-stick surface that withstands heat up to 300°C continuous, with excursions to 371°C, PTFE Natural™ coated forming mandrels provide a 0.05 coefficient of friction per ASTM-1894. After stripping the worn coatings, the mandrels are reconditioned and coated using a proprietary process which enhances their bonding surface and prevents cracking and flaking.

Applied Plastics’ Forming Mandrel Strip and Recoat Service is priced according to coating requirements and quantity. Quotations are provided 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.
