摘要： A molding apparatus is provided which is operated to mold an article having a hollow blow molded portion and a substantially solid compression molded portion. A mold is provided which has defined therein at least a first cavity portion and a second cavity portion. A parison is positioned within the mold and blow gas is injected into the interior of the parison to inflate the parison within each of the cavity portions. A compression member is then moved from a retracted position within a recess in the mold to an extended position outside of such recess. The compression member presses a first portion of the parison against the mold interior surface which defines the first cavity portion so as to compression mold a first portion of the parison. Inflation of a second portion of the parison in the second cavity portion accomplishes blow molding of such second parison portion.

摘要： In blow molding an article with a reverse fold, a profiled bar is positioned where the parting line of the mold is to be when the mold is closed. The bar provides a reverse fold in the plastic article during a pre-blow step. In operation, a pre-pinched parison is formed adjacent the bar and as the mold begins to close a small amount of pre-blow air is introduced into the parison folding it against and over the bar. After the mold is closed, blow air is introduced to form the part. A complex part with good wall distribution of material can be obtained by this method.
