Plastic is injection-molded successively in different cavities of the injection mold onto a three-dimensional preform made from a cut of a multi-layer barrier film, which multi-layer barrier film comprises a barrier layer coated with plastic on both sides. The plastic coating of the barrier film cut is at least superficially melted by the injected plastic melt. And the preform is supported by a support formed on the corresponding partial mold on the respective opposite side.

Abstract: Methods of forming multi-component reinforced composites are described. The methods may include forming a particle-reinforced component and a polymer-containing component where the particle-reinforced component and the polymer-containing component are in contact with one another. The particle reinforced component may be formed by a process that includes providing reactive particles that have a reactive polymerization promoter chemically bonded or coated on the surface of the reactive particles and contacting the reactive particles with a resin solution that includes monomers of a polymer. The polymerization promoter chemically bonded or coated on the surface of the reactive particles may promote the polymerization of the monomers. The resin solution may subsequently be polymerized forming a polymer matrix around the reactive particles.

Abstract: A method is disclosed for producing a piston (8) having a circumferential seal in the form of a circular cup seal (16). In a functional, installed state, the cup seal (16) has a profile consisting of a leg held in the piston (8) and aligned radially with respect to the piston longitudinal axis (19) in a radial region (17) and of a leg which is bent by approximately 90° into an axial region (18) and is aligned approximately parallel to the piston longitudinal axis (19). The cup seal (16) is mounted in a mold as a flat or arched preform (21, 21a) with a radial region (17a, 17b) which forms the approximately radial leg, aligned with the piston longitudinal axis (19). A circumferential region (18a, 18b) projecting radially beyond the mold cavity is shaped into the axial region (18) after removing the piston from the mold to obtain the functional contour of the installed state of the cup seal (16).
