With a total of six patents to his name, Raczkowski has developed innovative methods that significantly enhance the characteristics of extruded fluoropolymer tubing.
Latest Patents
Raczkowski's latest patents include a "Method and apparatus for drawing thermoplastic tubing." This specification discloses a new method and apparatus for treating extruded Teflon tubing to significantly improve its dimensional and optical characteristics. The diameter tolerance achieved is ±0.0002, with concentricity rising to 95%, and optical clarity reaching the theoretical transmittance of the material. The process begins with cleaning the tubing, followed by heating it to a transition temperature above 150°C to soften and further homogenize it. The tubing is then drawn through a polished diamond die and rapidly cooled. Additionally, the cooled tubing may undergo an annealing step for further stabilization. Both batch and continuous modes of operation are disclosed in this innovative approach.
