摘要： A molding tool and a method for producing molded parts from a moldable material with a first tool component and a second tool component are described. The first tool component has a cavity with a first molding surface and the second tool component has a second molding surface and a flexible material forming at least one portion of the second molding surface. In a first step, a moldable material is introduced into the cavity and then the second tool component is moved into the cavity. A second molding surface of the second tool component moves the moldable material in regions against the first molding surface. Thereafter, overpressing of the second tool component takes place after reaching a bottom dead center within the cavity, whereby the flexible material is deformed and presses the moldable material against a corresponding portion of the first molding surface.

摘要： A molding tool and a method for producing molded parts from a moldable material with at least one first tool component and at least one second tool component are described. The first tool component has a cavity with a first molding surface and the second tool component has a molding element with a second molding surface, which has an at least partially flexible material. Moldable material introduced into the cavity is pressed against the first molding surface at least in certain regions by the deformation of the flexible material. A medium is introduced via the molding element for this purpose, which leads to deformation of the flexible material.

摘要： The disclosed embodiments relate to a manufacturing component as a first tool in a forming station at least for endforming a preformed lid made from a material to form an undercut comprising natural fibres. The preformed lid includes a top part and a side part circumferencing the top part, where the manufacturing component is adapted to contact an outer side of the preformed lid to endform the preformed lid by exerting a first movement in axial direction along a center axis of the manufacturing component and a later second movement in a second direction towards the side part of the preformed lid. Multiple side forming elements of the manufacturing component are arranged to exert the second movement by applying an outer pressure onto an outer side of the side part to form an undercut into the side part.
