A method and apparatus for producing a plastic article. The plastic is introduced into a mold that can be tempered and that has at least one hollow chamber, the contour of which corresponds to the outer contour of the article. During manufacture, the mold is heated up and removal of the article is effected with a cooled mold. To shorten the cycling time, the inner region of the mold that adjoins the hollow chamber is cooled and heated at least partially independently of the outer region that is remote from the hollow chamber, while the outer region is held at a temperature that is higher than the temperature during removal.

[ What we claim is:] [1.] An apparatus for manufacturing a plastic article, comprising:a mold having at least one hollow chamber, which has an inner contour that corresponds to the outer contour of said article, said mold also having an inner region adjoining said at least one hollow chamber and an outer region remote from said at least one hollow chamber, said inner region being made at least in part of a material that has a different thermal diffusivity than does the material of said outer region;at least one insulating layer, which is disposed between said inner region and said outer region and has a temperature-dependent heat transfer coefficient; andmeans for adjusting said heat transfer coefficient of said insulating layer.
