Abstract: An apparatus and method for treating a plastic molded article. The apparatus includes a treatment chamber that can be closed and temperature-controlled. A vapor generating unit generates vapor of a treatment liquid. A fluid connection between the treatment chamber and the vapor generating unit feeds vapor to the treatment chamber and returns condensate back to the treatment chamber. A pressure equalizing device transfers waste air at atmospheric pressure and equalizes pressure with the atmospheric pressure during treatment. The pressure equalizing device retains vapor and prevents vapor from escaping into the atmosphere. A vapor phase is generated by heating a treatment liquid to its boiling point. The treatment liquid includes a solvent that dissolves or solubilizes the plastic. The article is exposed to the vapor phase for a predetermined time and removed from the vapor phase. Residual treatment liquid present on the article is removed.
