A non-destructive, direct method and apparatus for producing stretch blow molded articles having at least one physical dimension within a preselected range. The apparatus includes an injection mold defining an injection mold interior surface having a first differentially dimensioned portion disposed at a preselected location thereon and capable of producing a parison having a parison exterior surface including a first marker formed by contact with the first differentially dimensioned portion, and a stretch blow mold defining a stretch blow mold interior surface having a second differentially dimensioned portion disposed at a predetermined location thereon and capable of producing the article from the parison including a second marker formed by contact with the second differentially dimensioned portion. Relative position of the first marker with respect to the second marker indicates whether a dimension is within a preselected range. The method includes injection molding a parison so that a parison exterior surface includes a first marker disposed at a preselected position thereon and formed by contact with a first differentially dimensioned portion disposed at a preselected location on an injection mold interior surface, and stretch blow molding an article from the parison so that an article exterior surface includes a second marker disposed at a predetermined position thereon and formed by contact with a second differentially dimensioned portion disposed at a predetermined location on a stretch blow mold interior surface.

[ What is claimed is:] [1.] A method for producing a stretch blow molded article having a dimension within a preselected range from a parison defining a parison exterior surface including a first marker disposed at a preselected position on the parison exterior surface, comprising the steps of:providing a stretch blow mold defining a stretch blow mold interior surface having an elevated portion disposed at a predetermined location thereon; andstretch blow molding the article from the parison so that an article exterior surface defined by the article includes a second marker disposed at a predetermined position on the article exterior surface and formed by contact with the elevated portion, whereby relative position of the first marker with respect to the second marker indicates whether the dimension is within the preselected range.
