    摘要： The present invention relates to a process for the production of coated mouldings, by injecting a moulding composition into an injection mould and cooling the composition to obtain a moulding, and altering the injection mould in such a way as to produce an intermediate space between a surface to be coated of the moulding and the inner surface of the injection mould, and using injection moulding to charge a reactive mixture to the resultant intermediate space, where the temperature of at least a portion of the injection mould is increased for the curing of the reactive mixture.The present invention moreover describes a system for the conduct of the process described above.

    摘要： The invention relates to a device and method for producing thick-walled plastic molded parts by injection molding or embossing. The device comprises a mold for injection molding or embossing, having a cavity, and is characterized in that the mold comprises a wall region adjacent to the cavity, and a body removed from the cavity and adjacent to the wall region near the cavity, wherein the body of the mold is designed for a temperature T1 and the wall region is designed for a temperature T2 different from the temperature T1. According to the method, the temperature T2 of the wall region of the mold near the cavity is brought to and held at a value greater than the Vicat temperature Tv of the plastic molding mass before and/or during the injection process, wherein the temperature T2 is greater than the temperature T1 of the mold body, and the temperature T2 of the wall region near the cavity is brought to a temperature below the Vicat temperature Tv of the plastic molding mass during the solidification of the plastic molding mass. The result is thick-walled molded plastic parts, such as optical lenses and the like, having reduced shrinkage sites.
