ABSTRACT:
An apparatus for forming a thin-walled article comprising a frame providing a forming station for positioning a preheated sheet of thermoplastic material, first and second mold sections mounted on the frame in opposed relation with the forming station disposed therebetween, the first mold section having a forming cavity therein, the second mold section having a forming portion insertable in the forming cavity of the first mold section when the mold sections are displaced toward each other, the forming portion of the second mold section having at least one wall cooperable with at least one wall of the forming cavity of the first mold section when a preheated sheet of thermoplastic material is positioned at the forming station and the mold sections are displaced toward each other for sequentially shearing a blank from the preheated sheet of thermoplastic material and compressing the blank between the mold sections to cause the blank material to flow and form the article, means for ejecting the formed article from the first mold section and means for displacing the mold sections toward and away from each other.
