摘要： The invention relates to a method for injection molding a plastic molded part in an injection mold, comprising a) injecting a specified amount of plastic melt into the injection mold; b) introducing a compressed fluid between a part of the wall of the injection mold and the injected plastic melt; c) allowing the plastic melt to cool until the plastic molded part is self-supporting; and d) removing the plastic molded part from the mold. The invention specifies that, during or after step a) and during or before step b), the cavity of the injection mold is sealed against the environment, preferably by activating at least one seal.
