Latest Patents

Lehnen's latest patents include a process and apparatus for molding elastomers. This process involves the production of compact, shaped articles from vulcanizable rubber mixtures in powder form using a screw plasticizing unit. The method begins with the introduction of the powder-form rubber mixture through a delivery-active feed pocket into the extruder. The mixture is then plasticized in a mixing zone, compacted by combining the plasticized rubber particles, and subsequently shaped in a plasticized and homogenized form. Another significant patent focuses on the compaction of pulverized rubber mixtures. This involves forcing a vulcanizable mixture of rubber and additives through a diminishing cross-section, resulting in a granular, compact mixture with specific density characteristics.
