    摘要： A lamella block is provided for a calibrating device for calibrating an extruded profile. The lamella block includes a lamella structure, which has a plurality of lamellae that are spaced apart from each other by grooves and arranged in the longitudinal direction of the lamella block. The lamella structure has two lamella sets, wherein the lamellae of the first lamella set are arranged offset in relation to the lamellae of the second lamella set in the longitudinal direction of the lamella block. Further provided is a method for manufacturing the lamella block mentioned above as well as a calibrating device, which includes a plurality of the lamella blocks mentioned above. Also provided is a system for additively manufacturing the lamella block mentioned above, a corresponding computer program and a corresponding dataset.

    摘要： A system and process for forming an impact absorbing vehicle headliner extrusion including feeding a viscous polymeric material to an extrusion chamber, introducing a vacuum into an interior of the chamber, progressively forming the material into an extruded shape by subsequently passed through a series of sizer dies positioned at communicating interior locations along the chamber, and drawing an extruded profile out of the chamber prior to bending and forming into an overall closed profile. Pluralities of structural supporting ribs are formed within an open interior of the extruded profile. The chamber is separated into a front vacuum tank incorporating a first plurality of sizer dies and an interconnecting rear vacuum tank incorporating a second plurality of sizer dies for assisting in the formation of the ribs within a hollow interior profile associated with the extruded article.

    摘要： An extrusion die for forming polymeric foam sheets includes a first die body, a second die body, and a manifold within the first die body and the second die body, wherein the manifold includes an inlet to receive polymeric material. The extrusion die further includes a die exit formed by opposing die lips in fluid communication with the manifold and a temperature control zone adjacent the die lips. The extrusion die further includes two generally planar shaping surfaces in proximity to the die exit and place one above and one below the die exit. Adjustable shoes are disposed in proximity to the die exit on each side of the die exit and between the planar shaping surfaces.
