Fine Tubes

Outer diameter: 4 -0.25 mm / 0.157″ – 0.00984″
Inner diameter: 2.9 – 0.05 mm / 0.114″ – 0.00197″
Wall thickness: 1 – 0.04 mm / 0.04″ – 0.00157″

Our long experience in the production of wires allows us an upstanding fine tube manufacturing. This fulfills the wishes of a large number of customers who require a reliable quality for their products.

In addition to the various stainless steels, which are especially used in medical applications, we can also process other materials, such as tubes of precious metal alloys, gold, platinum, etc., but also non-ferrous metals such as brass, nickel, nickel silver, copper or different copper alloys.

High-quality precision tubes can be seamless and welded. We supply both versions with an accuracy of up to + /-0.001mm, straightened in defined lengths or in coils. We follow international standards and customer requirements.

Electroplating

We can apply the same metallic coatings as on the wires. Again, we have the possibility to reach acid resistance, biocompatibility, or to affect the electrical properties of the tubes.

Metalls: Gold, Nickel, Platin, Silver, Tun and many others…

We can electroplate Tubes and wires endless (reel to reel). Polyfil AG is very efficient and can garantie coatings to be homogeneous, without porosity (pinholes) or cracks.

Plastic coatings

For probes or catheters, it is often important that they are coated with with plastics. As for the wires, we can apply different types of insulation or biocompatible materials on the fine tubes.

With our multi-layer coating process, a 100% coverage is guaranteed. Pinholes can’t emerge with this technology.
