Title: Walter Knoess: Innovator in Sintered-Iron Technology
Introduction
Walter Knoess is a notable inventor based in Weissensee, Germany. He has made significant contributions to the field of sintered-iron technology, holding a total of 2 patents. His innovative approaches have led to advancements in the production of molded parts with enhanced material properties.
Latest Patents
Walter Knoess's latest patents include a groundbreaking process for producing sintered-iron molded parts with pore-free zones. This process allows for the creation of molded parts that are pore-free in specific zones while remaining porous in others. By utilizing conventional powder pressing and sintering processes, the molded part achieves a residual porosity of about 10% by volume. Additional steps, such as zonal introduction of materials or local mechanical recompacting, enable certain areas to reach a residual porosity of 5% or less. This results in a closed pore structure in those zones, ultimately allowing for a final HIP or sintering HIP process step that achieves 100% material density in the pretreated areas, making them substantially free from pores. The advantages of this process include improved material properties and the calibratability of the finished sintered molded part.
Another notable patent is the development of a heteroporous form tool for manufacturing casting molds. This innovation further showcases his expertise in enhancing manufacturing processes.
