Title: Alfred Krahl: Innovator in Polytetrafluoroethylene Joining Techniques
Introduction
Alfred Krahl is a notable inventor based in Eschborn, Germany. He has made significant contributions to the field of materials engineering, particularly in the joining of polytetrafluoroethylene (PTFE) materials. With a total of 2 patents, his work has advanced the methods used in industrial applications.
Latest Patents
Krahl's latest patents focus on innovative methods and apparatuses for joining edge surfaces of polytetrafluoroethylene materials. One of his patents describes a method where abutting surfaces of PTFE are placed in a chamber bounded by clamps. These clamps press the surfaces together while heating elements in the chamber heat both sides of the material. This design inhibits the volume expansion of the material during heating. Additionally, pressure generated in the chamber can be controlled by adjusting the position of the heating element. During the cooling phase, extra pressure is applied to the butt joint by moving one clamp towards the joint. A thin foil of a fluorine-containing thermoplastic is used to facilitate the joining of the surfaces. Another patent outlines a similar method, where heating means are spaced from the clamps and heat the material by radiation or convection, with a cooling arrangement to remove heat from the clamping zone.
Career Highlights
Throughout his career, Alfred Krahl has worked with prominent companies in the field. He has been associated with Sigri Elektrographit Gesellschaft mit beschränkter Haftung and Sigri Elektrographit GmbH. His experience in these organizations has contributed to his expertise in materials and joining techniques.
Collaborations
Krahl has collaborated with notable colleagues, including Gunter Freitag and Gerhard Ullmann. Their combined efforts have furthered advancements in the field of materials engineering.
Conclusion
Alfred Krahl's innovative work in the joining of polytetrafluoroethylene materials has made a significant impact in the industry. His patents reflect a deep understanding of material properties and joining techniques, showcasing his role as a key inventor in this specialized field.
